Hello Everybody, I want to start my thread by saying that everyone is invited to comment on my grows and give their critiscisms and observations.

Now for a one comment:
"Every theory and setup shown here is purely fictional and is not really happening. And the information in here cannot be used by anyone or against anyone as any other work of pure fiction."


VARIOIUS CHALLENGES:
WOULD AN LED AND FLUORO SETUP WORK AS WELL, BETTER, OR ALMOST AS GOOD AS MY LAST GROW USING THE SAME CLONES?

WILL ORGANIC SHORT CHANGE MY CROP TOO?

USING ORGANIC SOIL. FOR MY ORGANIC FERTILIZER, I AM BOILING FISH HEADS, GUTS AND SKIN, AND LETTING THE LIQUID THICKEN UP, ADDING BAT GUANO AND AN ORGANIC FERTILIZER TO MAKE SURE I GET ALL NUTRIENTS. I AM ALSO USING LAKE SILT AND COMPOSTING IN THE BACK. I ADDED EARTHWORMS AND VARIOUS DIFFERENT CONCOCTIONS OF ORGANIC INSECTICIDES READY.



I am setting up an LED/t5 fluoro setup. This will be a scale of about 60 plants when done. I bought The HPS's anyway, in case this fails or doesnt flower properly, inject it with either full HPS or maybe 6 hours out of the 12 hours when flowering, keeping my costs down and still giving me the FLOWER POWER. This is not my first grow, and I have used HPS grows with a good amount of success using regular grows.

And this is not my first LED GROW, this would be my second attempt. My first wasnt very good and I think for certain reasons other than the obvious HPS is for flowering. Ill give my reasons later, but in this I will explain my setup of LEDS and FLOUROS.
First I bought two types of LEDS, RED(630 NM) AND BLUE(475 NM).
I own now 30+ reds and 30 Blues. That would be good enough for 30 plants, one of each and could also have potential overlap if built in close enough.
My theory is, that LEDS and FLouros combined can effectively challenge HPS all through the plant cycle.
The flouros I bought were from Ebay and are plant specific. Since I already had two frequencies my theory is, that plants need plenty of the other light too. And with this will allow the plant to function properly with all necessary nutrients at the right dosages. (Iron is good for you, but it doesnt mean you going to eat a nail) and when all conditions are correct, give the plant a protein drink dosage of the blues and reds with the LEDS.


I ordered 4 sets of fluoros, with two sets of bulb configurations. I got the 2 cools Narrow spectrum bulbs, 1 red and 1 orange. My other kit has all red and orange. Which I will use for flowering including the RED LEDS. I will stay away from HPS and will only use at last minute if crop is not flowering well enough. I may be experimenting, but I am doing it on a larger scale and I am investing quite a bit more and at the end of the day, I have to get my money back for the grow. I will post and ask as much to avoid this and i will keep this journal updated.



For this I bought a few necesities at the hardware store.

My inventory included:
30 floodlights, WALL mounted, two lights model as long as its directional, so You can aim the beam, something i didnt do on my previous grow) and something I noticed from TM21thc with his thread and his successful setup so far.
https://www.rollitup.org/indoor-growing/14441-50w-killer-setup-god-knows.html

Two sheets of 1/4 inch plywood 8 x 4
Some good nylon solid rope about 75 ft long.
4 good metal cast pulleys
8 machine cut eye bolts with nut and washer
4 machine cut eye bolts screw tip ( to screw in to wood.
2 x 2 to be the support ribs for the 1/4" plywood to prevent bending with weight. 1?4 " plywood bends without supports, but If you buy 1/2 " plywood, its just oo heavy and it still bends. So put the 2 x 2 surrounding the frame.

I screwed in the 2x2 and then drilled straight through in eight holes and drilled holes at the same spots a pool table hole would be, all corners and two sides. For safety I added 2 more bolts on the sides. I cut two pieces of rope about 5 ft long each, burned the tips on the ropes and tied one piece of rope on one coner and tied the other end of each rope to the pertaining side eyebolts.

I drilled two holes into the cieling at 3 ft from wall facing the long side and at 28" from the wall on the wide side. Drilled another hole at around 7 ft from the first wall you measured. This will allow for the plywood to be on foot from one wall and 4 inches from the backwall, saving space, becasue with this setup I can move around closesly set lights. It doesnt matter If the cieling is vaulted, you just need more rope. Screw in the hook screw and hang the pulleys non business end into the hook. Tie a rope that goes from the floor, where the plywood is at present, and then thread the pulley and make sure that side reaches the floor, cut the rope and you should have about 16 ft. Burn the end and tie the rope using any marine knot that says would work for permanant knots in the little book that comes with the rope. I can guarantee that the knots that say (for temporary uses) will actually work as specified and even better.

Tie the two ropes attached to the eyebolts to the rope hanging from the pulley. Make sure you tie a nontightening knot, or use a rope ring that will hold the weight. Do this to both sides, (RECYCLING TIP)drill a hole into an excess piece of the 2 x 2 and thread the hole with the rope and use the 2 x 2 as a handle.
(I am definitely a tree lover)

Now that you can comfortably handle both sides and you notice the plywood is suspended and balanced nicely. Now I added the other plywood, setup the frame and drilled the holes on the roof, so both sheets are next to each other. If your worried about bumping and the just clamp both ends together. Dont fix both sheets together, cause then lifting would be tougher.

Now that both frames are hanging from their pulley system and you get a grip at what speed I should pull or let go of, I pulled the plywoods to about waist level and measured 6" from one corner and 6" from the 90 degree corner and drilled a hole at 6", then counted 12 inches away from the hole and drilled following the hole across the short side at 18". Then I added a 4 bulb 4 ft fluoro after the first row of leds then two more rows of leds bulbs, the one more fluoro, then one more LED.

At 6 kits per row of leds, im up to 4 rows of leds at 24 led lamps and I still have to hook up the fluoros. For the extra 6 inches left over, if you do it my way, you will have 6 inches left over, i addded a two bulb t8 fluoro.
As far as my knowledge goes, the two flouros I purchased are 400 WATT HPS equivalents on LUMENS and have 93% reflective hood. Again thats what the manufacturer stated.

By adding a two bulb t8 I cover the dark area in the room. I wired all the cables with high grade romex and tied all cables together. I figured with my math this setup would be about 150 watts total enery and very little amps. Plus I have had the bulbs on for a week, without the flouros to test heat and the room stays as cool as a cucmber. With no huge AC on. an 8000 BTU that runs during the hottest time of the day and when the lights are off. ALL WINDOWS ARE SEALED and using insulated reflective 1/2 " thick sheets on the walls and window, after covering up and adding a motion controlled night light, that gives the appearance of someone turning on and off the lights at random times through a thick curtain. TOTAL ISOLATION.
I have only 18 baby clones now and one mother. I only kept the mom from my last grow when I moved all my things "in the cover of night" to my present grow room.

Wish me luck everyone, and if anyone has any questions, you are more than welcome to comment and I will have some pics soon, but not until my damn t5's.

ONE SIDE NOTE. I am using YEAST, WATER AND SUGAR AS MY carbon dioxide machine. I just got a little electric warmer and put it under a 2 gallon pot running around 105 degree F. Very safe and pretty reliable. I dont have a gas tester to calculate exactly how many exact PPM I have in the room. If someone wants to test this method I am using simple active yeast from the supermarket adding water and sugar.

The reason for this specific setup is for one theory I have is that plants may survive and even l;ook normal with only red and blue leds, but the plant still needs a full PLANTFULL of the FULL useable spectrum, but limiting the harmful and useless ones to a minimum and maximizing the light consumption of the good spectrum, therefore giving a balanced diet but always making sure they are still eating healthy. Plants absorb, not only water as when people call them thirsty babies, but also need a good dose of light. SO MY CHALLENGE IS ON, I BELIEVE USING THIS COMBINATION I WILL BEAT OUT A SIMLAR HPS GROW WITH TWO 400'S. I have grown under HPS sungrow before and took out some delicious colas my friend does the same. I think I can match or beat the performance.


I WOULD LIKE ANYONE TO COMMENT SO FAR.

you got any pics of your setup?
You're obviously using a lot more light than any other LED grow I've seen, and it will be interesting to see how the LED's act as supplemental lighting to the flouros. This is obviously a test of LED's, but it will be difficult to pinpoint what exactly their effect is with another light source present. What LED's did you grab? Been looking at luxeons and other high power led's, but the wavelength is not worth the price in my opinion. will be following anxiously...
Good luck!

This will realy show what LEDs can or can not accomplish. I too will be looking forward to see this thread develope. Good luck bro!

thats gonna be a nice setup. you got 30 of those grow bulbs? that must of cost a bit. I'm glad to see that more people are experimenting using leds.

I'm also doing a LED grow. My girls are going into their third week of flowering using about 92 watts of CFLs and 35 watts of LEDs. I have several hundred red (625 nm) and a couple hundred blue (472 nm). I've had great results so far. I plan on posting the grow journal at some later time.

Sorry if im hijacking your thread. but here is some pics for ideas :D There are four LED panels now and also 4 CFLs. currently 3 plants :blsmoke:

Hello Everyone, before I post and comment on questions, thanks for the support.
And I hope this will be a worthwhile experiment.
Updates: I just got my fluoros and hung one side up, since I still have about two to three days before I pot my clones. Guys, I am starting this grow journal from the beginning.

Hey Ad, awesome setup and I must ask what reflectors you are using. The only dislikes I have with CFLS are three: They crack sometimes when just doing the mundane task of screwing the bulb in. They are hot. Hotter than t5's since they are more tightly wound and the whole interior of the light spread is lost and not very useable. But otherwise, I have used CFLs even until today for cloning. So hey.

On the LEDS, I just ordered a PAnel Board to build my own LEDS. I am not starting that until I am finished receiving a spectrometer which I will use with the results I get to try and see If I can get better results.

On the luxeon Led bulbs, I didnt buy any and I didnt buy one either. They may be onto something, but I have to finish up my setup and then give them a test.

Luckilly, I have LEDS from different suppliers with different Frequencies on the blues and reds which I happen to have enough of to put one row per Light Type. If there are vast differences in performance, I should notice it within a couple of weeks. I will label which row is for which LED Type.

It would be nice to test out solaroasis and the Luxeons, but hey, I got anough skin in it to qualify my grow as AN authentic LED ATTEMPT. Maybe next grow, I will have some other setup on another board.

Here is one of my 4 t5 fluoro lights. Hung up and shining brightly on my recently moved clones.





And here is one of the other ones right out the box witht the blue plastic still on to protect the reflector.



Here is a picture of one of the LEDS from the same ones from justblissful on Ebay but they come double colored . Just got it from ebay:



These are the GRO TEK 8 packs on Ebay they are 662 NM have a reflective backing and supposedly range all up to 680 NMs. They look good and sturdy. Btw, This will either help them or sink them, but I am here to test and I have no skin in any of this to protect but my own:


The Blue one I have is from my first person whom bought the LEDS from. I am using only their Blues now, because the REDS come out of the sockets when you run it 24/7 even when I reglue. They are from USGrowlights.com, but it goes under the 168 RED LED Kit from justblissful in Ebay. Theyre Red and Blues are Red 670 and Blue 430 NMs.
Here is a pic of all the different models


from left to right GROTEK nice looking bulb next two Just blissfuls second order bulb which looks different from the first ones this is the two toned.
The lower content LED is from usgrowlights.com first order. And the right one is another from GROTEK.

More lights to put up


spot Light kits I purchased from hardware store:


Yeast, sugar and pot with evidence of bubbles. CO2 bubbles to be exact


Pulleys and frame and BABY CLONES, filter and A/C. One note, the ac wasnt on and the room stays pretty cool at 80F. With the CO2 bubbling the plants should be ok.









******quiz question of the day******ONE LAST QUESTION FOR ANYONE OUT THERE. IF MY ELETRIC DIAL DISC WITH THE BLACK STRIP TAKES 48 SECONDS TO MAKE ONE REVOLUTION WHEN ROOM IS OFF AND 31 SECONDS WHEN IT IS ON INCLUDING FAN AND AC, WHAT IS MY EXTRA KILOWATTAGE BEING SPENT?

tHANKS AND SORRY IF THIS PAGE COMES OUT ALL MESSED UP.

I have posted this thread update 3 times already, and each time it never gets added. Third times the charm?

Thank you to everyone who has read and commented on this website.
AD I think you got a hell of a grow room and hopefully you can tell me what reflective material you used? Is it mylar? The only thing I dont like about CFLS are:
They are hot, hotter than fluoro tubes, because they are tightly wound up.
Most of the lighting action is going to the lighting the light itself(just look on the inside) If only we can make a CFL with a twist large enought to fit a tree inside. Like an Atom. Stoner moment...
And they tend to break easily in the base when screwing in.


Well, I got my T5 fluoros, but they came in without the special bulb request. GRR. But then again, who am I to demand they get the order right when I paid only 160 a piece for these lights? Thankfully my babys are small now. I just put them under the fluoros for the next couple of days while I finish.



Alright I will try and copy and save what i write, cause I dont want to lose it again, literally.

These are my t5s they come in 4 bulb units and they are about 10" wide. Not the 20" originally thought. They are thought to have the output of a 400 HPS. I got them from great lights 4 less. If you do buy from them, make sure they get the bulbs right. NOTICE THE ROW OF LEDS IN THE BACK


Other fluoro ready to install still with protective blue coating.


I will be setting up the LEDS by row, only one type of led in each row. To make sure I get a reliable comparison that if any one light is better than the other, I should see a result. If not then, they will be equally good or bad.

I got the these red ones from GROtek, they go from 662 NM to 680 NM.
I have enough of these to set two rows.


These LED Double lights go from 430 NM blues to 670 NMS, red. They come from usgrowlights.com
And they pulsate under the camera.


These older ones I got, also seem to be from usgrowlights and are solid red or blue. The only problem with them, is that when they heat up they tend to fall out of their sockets, and they also are not to clean, with lots of the white enamel still stuck to the bulb decreasing light output. The newer ones are better, but the old ones I am going to put up anyways are not too good.


Here is the room setup. NOTE I have not put the reflective material yet. I am literally starting from scratch.
Pulleys, frame and rope Note I am only using one side while I finish the rest of the wiring.





More LEDS going up




LIGHT KITS AT HOME DEPOT. VERY ADJUSTABLE AND MOVEABLE.


MY CO2 GENERATOR :)
WATER, SUGAR, YEAST AND A POT $20 co2 generator, no risk of blowing up too.
NOTICE THE BUBBLES? These are good bubbles. they are co2 bubbles


my a/C I rarely turn on since the heat inside the room is about 81 82 F.

Check in tommorow, I will have some more updates, since I plan on finishing the frame tonight.

****POP QUIZ FOR ANY MAJOR TECHIES****
AS A TEST TODAY I WANTED TO CHECK WHAT ONE T5 4 BULB, 12 LED LIGHTS A AND 52" CEILING FAN WOULD CONSUME. THIS IS WHAT I DID
MY ELECTRIC DIAL DISC COMPLETES ONE ROTATION EVERY 48 SECONDS WHEN THE ROOM IS OFF
WHEN I TURN ON ALL THESE DEVICES MY METER STARTS ROTATING ONE TURN EVERY 31 SECONDS. CAN SOMEONE CALCULATE THAT AND GIVE ME A ROUGH IDEA OF HOW MUCH KILLOWATTS/HOURS THE SETUP IS SPENDING SO FAR?

I ALSO BOUGHT AN LED PANEL KIT AND A SPECTROMETER. I AM BUILDING MY OWN LEDS BASED ON INFORMATION I WILL COLLECT ON MY GROW.

tHE BABIES WILL BE ON POTS IN ABOUT TWO TO THREE DAYS. When I said, I was starting up from scratch I meant it.

looks like a setup similar to what I have. I used plywood and erector set for my light fixture :D.
The CFLs have coke can relectors on them... not hte best, but does make a difference. For reflective material i used mylar. works the best and can withstand heat pretty well.

If you are building your own LED arrays, I found the best way to power them is to use an old computer power supply. group them into a combination of series and parallel. its very tedious soldering all those freekin leds. lol

where did you get you leds set up from. or was that something you build yourself

sorry I got a little distracted with computer issues and laziness :roll:

where did you get you leds set up from. or was that something you build yourself
I got the LEDs from ebay, the soldered them onto pref boards and whatever I could find. I must say though that after soldering hundreds of LEDs like xmas lights together... I should of just bought the premade ones. although I did save a couple hundred dollars doing it myself... it wasn't that bad after a bowl or two. lol

would there be any way you could get me the link or the spec on the led supplies (nm , bulb ,housing ect)you used. im have some good soldering skills and dont mind it if i can save some cash.

have you any idea of the lumen output of that LED setup?
Lumens don't matter. Lumens are how bright humans see the light... plants see different colors stronger. (see pictures)

Humans see green/yellow the most, and plants see green/yellow the least. Many lights that are designed to be bright in Lumens are strong in colors that plants don't even use.

I'm not in the growing stage yet, but I've designed an LED light that has some color in all areas plants use, throughout the spectrum. It's strongest in the red & blue ranges that plants use most, though spread out wider over that range... like HPS. You can see my LED design at: https://www.rollitup.org/indoor-growing/186051-my-lighting-project-will-custom.html

Best of luck... I'm subscribed. :leaf:
