Whats the best way to get rid of an aphid problem, I have washed the plants on two different occasions about a week to two weeks apart and they keep coming back.....arghhh!

First get yourself some lady bugs. After you're out of those then try a HotShot Pest Strips. They have worked well for me with fungus gnats and kill just about anything that flies. You should be able to get a grip on them with that.

I am starting up my room which is 10X10 with the Ebb & Grow system running 12 pots. I am planning on using MH for veg and HPS for flower with 1000watts. I have a Raptor hood and an XtraSun ballast.

I am wondering if anyone has ever used an XtraSun ballast and if they work good or are a piece of junk? I havent been able to find any review on this ballast yet.

I am also wondering if I have to vent the room or will the fan in the room be enough?

Also any info on vegging plants under MH?

Thanks!!!!

If you do not air condition the room (5,000BTU) then you will need to ventilate it. No info on the ballast, sorry.

Also, a 1000w is good for, at best, a 5x5 space. You'd need at least Four bulbs in there to actually fill the room. I think two 1000w systems would be better suited to that number of plants. Perhaps you'll manage to put together another $300 between now and the beginning of flowering when you'd really benefit from the extra wattage.

You need to be aware of amperage. Most residential circuits are only good for about 1800 watts. If using an AC system you'd need to be aware of that, as a 1000w lamp, 800w AC unit, plus fans, will probably trip your breakers or present a fire hazard.

I veg with a 1000w Metal Halide. Works wonders.

I am not planning on running AC because the room is in my basement and it is pretty cold down there year round. I guess I will have to run some kind of ventilation. Do you have any info on how I would do this? I was going to do a tent and the ventilation for that was easy because the holes were already there....Then I decided to just build my own room because it was cheaper. Would I set up the ventilation the same? Run the intake at the bottom, then through the lights, then back out the top of the room? How soon will this have to be done?

The dude at the grow store said the 1000watts would be good for a 10X10 with 12 plants with the Raptor hood because it is so big. That raptor hood is a monster! lol

More wonderful news I hadnt thought about really....amperage! There is only 1 outlet and I was going to have to run an extension cord over to the room to power everything up probably with a surge protector. Do you think that will be ok? Or is that dangerous?

As for vegging with the MH...When do you put your plants under the MH and how far away do you keep the light? I know MH is a lot stronger then the flourecent lights and cant be kept to close or it will burn the plants.

Thanks Snow Crash!!!!

I've managed to keep my 1000w lamp and 5x5 tent at the perfect temperature so long as the intake temperature is beneath 72 degrees year round.

Passive intake at the bottom of the room, connect ducting to one end of the reflector and leave the other end open (or connected to a carbon filter) and pull the warmer air from the grow room through the reflector and then exhaust either back into the "buffer" air room (where you are intaking from) or directly outside.

Everything should be in place before you start growing. So... you need it done now.

The size of the reflector doesn't make the bulb stronger. What you need to understand is the rule of squares. Basically, every unit of "1" distance you are from the bulb the amount of energy available is reduced exponentially.

At distance "1" you would divide the total lumens [145,000] by 1x1. 145,000/1=145,000
At distance "2" you divide the lumens by 2x2. 145,000/4=36,250
At distance "3" you divide the lumens by 3x3. 145,000/9=16,111

Get the idea?

For HID bulbs the distance of "1" = ~6.8 inches.

Photosynthesis requires a minimum of 2,000 lumens to maintain life. 5,000 lumens is what the plant really needs.

The maximum distance you can stretch a 1000w lamp is about 58 inches. So... yes, you can cover your entire 10x10 area with just barely enough energy for life to be sustained outside of the inner 6x6 area. Inside the 6x6 you are working with 5,000 lumens.

Just understand that at 5 feet from the bulb you are working with about 1/80th of the energy. I do not agree with the grow store guy. Mostly because to light an area that wide you would need to have the bulb at least 3 feet above the canopy. A little trigonometry and you'll see that the hypotenuse representing the distance from bulb to top of the canopy at the edge of the garden exceeds the maximum distance. Even with a great reflector.

I prefer my 1000w lamp in a 5x5, you might be able to push it to a 6x6, but I don't think going much larger is going to help your final harvest weight much.

I move my plants from under their CFL bulbs at around 15 days into life. I start with the lamp about 30 inches above them and just let them grow into it. Once they are 30 days old you can push them pretty hard with light and nutrients (so long as everything up to that point goes swimmingly) and you can keep the 1000w lamp about a foot up by that point without damaging them.

Yo crash, I got my plants back to guzzling nutes and here are the latest pics of my himalayan gold. im using AN Connoisseur flower, AN Big Bud, AN Bud Candy, Botaincare Sweet Berry Carbo, & Emerald Triangles Snow Storm Ultra at the specs you suggested before. im at week 5 of flowering and running Connoisseur at 10ML of each A&B in 4gal of water, 6ML of each B.B., B.C., & Sweet Berry per 4gal, and 2.5ML of snow storm mixed to 1qrt in spray bottle i spray each night. i have to refill the dwc about 2gals every 2 days. should i add same amount each time? the water is staying healthy and clean. i add about 10ml of hydro peroxide each feeding. is that too much? being a lil more knowledgeable i see i chose a medium strength strain & i shouldnt expect an amazing outcome but its an easy strain to grow and very very durable to hiccups. ive actually just ordered tangerine dream from barney's farm and an ak47 x jack herer from sensi seeds. now those i have a green thumb stiffy just thinking about them.

Combat Veterans For Cannabis - Recon!!!

These are in a 3x3x8.5 room

now that i sit back and look how much im feeding it does appear to be quite a lot...im gunna check the ph level....

well i just got my ph meter and calibrated it the other day...the res was at 6.8ph level and well i see that using tap water is detrimental to maintaining the correct ph level considering it comes out at 7.1...what can i use to lower that number to around 5.8? the ppm after i just filled the water up to bottom of basket is 220ppm and before i filled it was at 660ppm. i added about 5000ml of H2o to the 4gal res...whats thats about 1.5 gals, i think..i also think i read that around 600 is the target number...???

Hi all Just started my first grow am going with soil to start,, all ready burnt my clones in rockwool, but not the soil???strange!! have been getting clones from all kinds of freinds, strains I never even heard of, but the going is really slow, to much nuts i think, just moved the 1000 watt hps's together from 4' apart to 2.6' the shed is 28'x16' with a 12'x8' veg rm inside & slopping roof, an 8'x16' sealed room for ballist, elect. vents, airconditioner, fuse box & more and am thinking about getting tubes in the veg rm, the mh 1000 is to hot, and am going to put a co2 gen. in later $$$$ is a prob, so what do i need to do or change???, would love some input. also am a card holder for myself and another so 12 biggies and 36 small 1'x1' at the most. MUST STAY Legal.

You seem to have a lot to say... but without asking many questions.

You need to maintain as constant a pH and PPM as possible in your reservoir. Every time you top off the rez is an opportunity to manipulate the EC, pH, and nutrient ratios.

Hydro pH is 5.5 to 6.0 with a focus at 5.8 being ideal for most plants. Ideal Hydro EC range is 1.4 to 2.4 with a focus around 2.0. If your nutrients do not lower the pH enough then you'll need to use a pH down solution. There are many on the market and they are affordable and long lasting.

You are using good levels of nutrients though, 2.5ml/gallon of A+B, 1.5ml/gallon Big Bud, 1.5ml/ gallon Bud Candy, and 1.5ml/gallon Sweet sounds actually a little lower than what you "could run" but based on the look of your plants I don't think you should go changing anything major at the moment. There's the slightest bit of burn on your leaves which could be from many things.

Of any suggestions to make as the grow continues, you could drop your Connoisseur down to 2ml/gallon and increase the Big Bud, Bud Candy, and Sweet all up to 2ml/gallon as well. That will create a gentle increase in the P,K, and Mg ratios against the N and Ca ratios which is ideal for weeks 4-7 of flowering.

Watch the plant for deficiencies. If you start to see leaves draining of color without burning then that is a good indication that a touch higher EC will help the plant.

Looking good.

I'm not entirely sure what you just said... Might do this... Might do that...

Whatever the case your grow room looks baller. Get everything set up and test out the temperatures and humidity before you get knee deep into flowering and you need to make changes. A dehumidifier would be a good addition if you didn't list one. They do need to exhaust heat so you'll have to accommodate that.

hello- need some help on what is wrong with my plants and how to fix them- i ll start with i think it was overwatering but not positive - my ebb n flow kept overfilling and not draining all the water out, we have corrected this problem, i believe by adding the anti sipons -they where missing from my order and i didnt know- now my plants look very wrinkled one is still only about 10in tall comapred to the rest, they all had this problem and finally started growing tall, the leaves curl in all directions and yellow and brown and break off. leaves on the bottom and under are very small, it seems the fan leaves yellow more than the other leaves. i have one stinky pink it was doing the best and then i took clones from it and since then it behaves like the others, except she is not budding at all. yesterday i removed most of the damaged leaves so there are before and after pictures no more than 10 days apart, the thing is they keep growing -i just dont want them to die and i want the buds to get big, what can i do? the ph i 5.6-5.8, i only added stardust to this last water change and two days later added micro by GH, yesterday i added sea kelp per my local gro store, the water temp is 78-80 and the room is between 80-85 with lights on light off 72-80, i run a 1000watt hps with an open hood -just the metal reflector. the ppms are between 1700-2100, the alkalinity is done with a test strip so i cant say the exact but it is where it should be less than 90(also per my local gro store) i run a floor fan on max not aimed at my plants, i want to start nutes up again but am afraid to any suggestions? i have the 3 part GH and also the technaflora starter set to use, i have some b-52 and revive. i was using some of these during the veg. i am about 2-3 weeks in to the bloom stage, the plants are 1 stinky pink, 1 white widow, and then the 4 blue dream ,and the small one is a maui waui we had more but they didnt make it-the BD shows the most damage but they all are doing it, the tops of the plants are also discolored compared to the rest- like the green is more florescent green. take a look thanks for any help-sandee

sorry the pictures are not in order but the orange ones are with the lights on and taken before i cut the bad leaves off or most of them off.

Just got these plants... Do they look healthy? Should I repot them? How much water should I give them, and when? And what strain they look like? Also I believe they're female clones, but can I get a second opinion?

Your ppm's are WAY too high. An EC of 4.0 is not normal. Also, you shouldn't be just adding a little of this, and a little of that, a dash of micro and a dollop of kelp... You should be mixing up a balanced nutrient solution and using that to keep the reservoir full. Then once a week (or so) you drain the reservoir and start fresh.

Revisit how you mix and prepare your solution, drop your ppm's in half, and it may help to flush your system. Clear-x would be a good addition.

You are burning the shit out of those plants with too much food.

They are female... And flowering. You should definitely transplant them as the clear cups are terrible for the roots.

Water when the soil becomes nearly dry. Use the weight of the planter to determine when to water. It should feel feather light before you water it. Always water completely to saturation, with at least 25% draining from the bottom of the planter to ensure you are washing out any build up and to have evenly watered the entire media.

Transplant to an organic soil, or coco mix, and be sure to incorporate at least 25% perlite in your mixture so as to maintain a proper aeration of the media when saturated.

Do some homework. There are many books and resources for you to read so that you can act for yourself in your own grow room.

i think u mis understood- i did drain the reservoir and on the advice of my local grow store i added the sea kelp, his suggestion was to not immediately start up the nutes - I listed the nutes that i have at home but in no means did i say i use them all at the same time or even any of them at all- i bought different products 6 months ago to see what i would like the best, the only thing they have had in the last 2 week is the star dust and micro and that was added the day i changed the water -so 10-12 days ago and the sea kelp i added yesterday, my next water change is thursday or friday, so are you saying use the regular 3 part system which hasnt seemed to be working, and as far as ppm i dont know much about that only that from day one mine have always been at a steady incline from 0 to what they are now, how exactly do i lower them and when? i add nutes per directions to a gallon or so of water from the reservior pre mix it and then at it back to the reservoir and check the ph and make adjustments if needed, wait a day and then do the next as it says not to add them together because of lock out. im looking for suggestion and advice- thanks

Growing isn't for everyone...

How do you lower your ppms?

Did you even bother to ask this question of yourself? Less nutrients, it is that simple.

I question your dedication to the craft. Nutrient systems are available for a reason, and you are fucking with ratios and adding shit because the "dude at the store said so."

I'm also unfamiliar with Stardust, or its NPK ratios.

You need to do a lot more research in how to feed plants, especially in hydroponics. Find yourself a good nutrient system, or begin using the Lucas Formula if you have the GH 3-part system. The best investment for your room right now is a good grow bible. Take a look at what other people do with their nutrients. There is a wealth of journals and knowledge here for you to learn from when it comes to mixing nutrients.

Hell... There's an entire subforum for nutes. I can't tell you what to use when I don't know exactly what you have. Stardust is a mystery to me.

GH 6/9 micro/bloom works very well for a lot of people. Again, I recommend you drop your ppm levels to at least beneath 1500 or, more ideally under, 1000. A 2.0 EC (double the ppms to get your EC, probably) and now you are in the right range to grow plants in.

Also, in order to resolve your issues and questions it would help to be a little more formal in your grammar and articulation of ideas. Don't just spew stuff out. Organize your thoughts and formulate a proper question. Paragraphs and complete sentences will go a long way to helping you, help yourself out.

I think you are making this harder than it is. Mix your nutrients on the side. Use a known effective formula that you have access to in the GH products. Keep your ppm levels where other people keep their ppm levels. Keep an eye on your pH. Then just let the plants grow. Up to this point you've been using far too much nutrition and it is evident on the plants. The fact they are even alive is testament to just how resilient a plant Cannabis is.

'growing isnt for everyone,' -no its just not for you alone- growing isnt your invention- you are not the grow god or the know god- if you where you would be more articulate- you know much more of an educator than someone how woke up on the wrong side of the bed or got dump by his girl, cursing at complete strangers for asking for your help. funny your unfamiliar with stardust as if thats ok but its not ok that i'm not unfamiliar with something. oh this 'who needs help ask here is for people who know and just want someone to back them up? or its only for people you like, and i took the information from greenfire-look it up top hydro store in sacramento-just as i would have from you- but with your attitude if you yelled fire i would nt blink- if thats what you wanted to accomplish you did and should be ashamed of yourself.-the only one spew shit out is you and no matter who grammar efficient you are it still sounds like shit, just because you can place a period and a comma doesnt mean your not an asshole. your a true fucking poser who thinks that they are the only person in the world who knows shit about shit and in reality you are shit, if you where trully dedicated to the craft as you say you'd be more informative and helpful, not angry and vengeful. your like the hippie that likes to fight and beat people down, you go to a concert light it up but don't pass it around, you grow your hair long but roll your windows up when a rocker walks by, THANKS YOU'VE BEEN SO HELPFUL

LMAO!!! Wtf, right?

Whatever lady. Keep burning your plants up. You totally seem to know what you are doing.

Interesting how angry ignorant people are when you rub it in their faces. Asking how to lower your ppm levels is what gave cause for my reply. Of all the things to ask... the answer is simple and obvious. If you don't see how obvious it is... this is not my fault. I assure you though, lowering your ppm is the answer to your problem.

I don't believe the purpose of these places is for people who don't know what they are doing. It is for people who know what they are doing but have reached an impasse and require a little advice. I spent years in research and growing before bothering to even try to help people.

Everything you need can be downloaded in the Growing Marijuana torrent. Contains DVD material, multiple books, bibles, and articles. Once you read through that torrent then you can start researching what other people do and what works best. Then you can try to imitate. Then you can try and do it all on your own.

Basically you've jumped to doing it all "your way" depending on advice from store employees who aren't in your garden.

Asking the questions you ask is the only reason I chose to address you in such a manner. Had you done the proper amount of research you would be asking much different questions.

You have your answer. Doesn't really matter if you like the extra you needed to choke down. I don't care what your Sacramento Grow shop claimed. Stardust is a 12.5-12.5-33 nutrient. It is very likely you are running entirely too much potassium.

Have fun acting a fool and alienating people. I'm putting you on ignore. Ignore means that no matter how much you cry, I'll never, ever, read it again. You will probably still bother to try and get in the last word but at the end of the day... It's only going to raise your blood pressure. Take a hit and chill out on your nutrients.

Take it or leave it...

newbie central- implies NEW-you're an idiot- if it is such knowledge than why is it listed as #17 of 101 already asked questions? you make a great teacher-only ask what people haven't already asked and if you ask something that I already know than you're dumb, you have a great mentality with that. you open your reply with hostile comments and got mad when i asked you more questions- i tried to ignore your first rude reply and tried to understand what you where saying so i asked about ppm's as does 100's of other newbies do here everyday -but i' the stupid one right, now you want to go back and answer the questions no thanks- as far as research i thought that was what i was doing now but i got you answering on the forum instead. no need to reply i wll come back when you aren't answering questions.

Thanks Crash, not much of a typest, can only make these two fingers move so fast, so by the time I finish typing my mind is on another question. I have been checking the temps every two hours and am dialing in an exhaust fan on a timer, just picked up a dehumitifier at harbor freight for $109. on sale "cool" the light in the veg room needs to be cooler!! Tubes?? less watts?? 1000 mh, flood table is 4'x8' with a little tilt. Guilty I did not know these sights even exited untill I found this sight almost two weeks ago, so not much research done outside of testing bud which got a little spendy.

As long as the intake temperature is maintained beneath 74 degrees you should be able to manage the heat with an appropriately sized exhaust fan.

In my ~150 cuft space my 400cfm fan (with carbon filter and about 8 feet of ducting) keeps the area about 2 degrees warmer than the intake temp. I'm probably venting the tent twice a minute.

If you are having problems with keeping the room cool I don't think less light is going to be the resolution. Upgrade your ventilation fan if need be and ensure you have access to plenty of cool air.

If the temperatures in your area exceed 80 degrees there's very little chance pulling in 80 degree air and keeping the room cooler than that. This is why it is important to use a buffer room to condition the air to the proper intake temperature before allowing it to be pulled into the grow space.

Intake temps and ventilation. Thats all you need to manage excess heat.

Air cooled reflectors will help prevent the "bubble" of heat from the bulb which allows you to keep the lights closer to the canopy but they don't do much for keeping the room cooler on their own. Any one reflector will be as good as any other at keeping the heat from escaping into the surrounding space.
