hey potman listen..im doing this hydro unit with ebb flow etc etc and ive bought also the co2 tank kit as reserch told me it could be good for plants(ive tried the cheap baking powder method and it worked) so i figured i would but a good 1 for my big ass new room..could i use it directly in the water connected to the ph controller to mantain good ph levels??? , because i think (and also some have told me) that roots dont need co2 and it could be irrelevant to use it that way....
should i just diffuse it infront of a fan just to create co2 for the plant leaves
or should i 'waste' it on ph matter? (although i think ph is the biggest matter )

also i was thinking of buying a 3 slot nutrient feeder Aqua Medic : Freshwater Catalogue : Dosing : Reefdoser to brag about how hi-tech my shit is!!! (Actually because i suck in this shit and i want it to be easier for me since ive got a big budget to spend on something that might not yield!! lol ) would you reccomend it??

......one last thing , i currently am on the 3rd starting week of a single female plant its a white widow female sensi seed... when the leaf is small it has a rich green colour..then as it ggrows it loses the colour (as in light green not pale) ..is that why they call it white widow? or is it because ive got a problem???

Extra CO2 is good for your plants, but only if you leak it slowly over their foliage. It is heavier than air so will sink, so an oscillating fan on the floor will stir it up. You still need to control the exhaust and temps in the room.

Check out the automatic nute feeder after your 20th crop.

I can't tell if your White Widow plant has a problem, you'll have to keep a close eye on her.

Hey Potroast, great thread. I have a drip sys. in rockwool. I have 6 ww girls going into there 4th week of flower. I have a strange problem and can't put my finger on it. I have 2 girls that are driving me to a nervous breakdown. I wish I could take a pic. of this but my camera sucks on any kind of closeup. The problem started about a week ago. They started flowering big time and getting cola's under my 400 hps. I had one plant get too close to the light and got some burning. I move the light up everyday but leave some close to accomadate the lower buds. Well the buds tric's stopped growing and the buds are becoming some what packed with unusual density. I have 3 other girls looking perfect but I don't know what to think of the 2. I am using floranova bloom with florilicous plus and Koolbloom. My question is if you burn the plants what is the condition of the plant. Can it come back,will it come back this late into flower. I really am not sure this is the problem. Only thing I can come up with. I already have made this a long post if you need more info for diagnosis let me know. One other thing Iam losing A LOT of lower leaves a fistfull every couple of days. Most plants bottom half leaves are now gone and more on the way.

Just thought of some additional info. I am having a slight humidity problem with summer here. The humidity keeps at around 35 to 55. Mostly in the 40's. every once in a while it gets up around 60 to 70 never more than a couple of hours. I have 1 pu fan on the bottom and a intake about 70cfm for the tops and a clip on fan blowing on the bulb usually around high 70 to low 80's. Constant fluc though. Thanks

WWgrower, a 400w HPS without an air-cooled hood should be 15 inches above the plant top to keep from burning the plants.

When you add Kool Bloom, you need to cut down on your basic nutes, so the FloraNova should be less than 10ml/gallon, maybe 5-7ml.

As plants flower, and get taller, the lower leaves get less light, and are used by the plant, so naturally yellow and die. At this point, you can only let your plants mature as best they can. Give them more fresh air, and more circulation, because in late flowering they need it.

Thanks potsoast, Did not know that about the floranova but I keep my PPM's at 1300 before I add the Koolbloom. Also I thought or was using 12 inches away from light I will move it to 15. When a plant gets overheated and burned how long will it take to recover if at all. Two plants this happened to over a week ago have not recovered the buds are not fruiting up,like the others. Thanks

sorry to change the subject but I flush after 5 weeks of flowering,I want that white ash bra.my 2cents peace PH2

The FloraNova is a mostly organic nutrient, so it's more forgiving than a strong chemical nute, but you still want to use less with the Kool Bloom, and the plants don't need as strong a nute mix in late flowering anyway. Also the Kool Bloom is strong stuff, so use no more than a level teaspoon per 4 gallons of soup.

Once foliage is damaged it won't recover, and the bud amount around there will be less.



You can flush after 5 weeks, but you'll want to feed them again in the next 5 weeks.
Unless you're growing some kind of Haze, then you'll have another 7-8 weeks.

Hi potroast im new to growing an i got some skunk#11 feminised seeds, planted 2days ago and already hav 3 little sprouts. how far away should my 250w MH be?
and can i clone feminised plants cos ive heard they die off pretty early is this true?

OK. Switching to hydro next grow. Lots of questions. I will be doing an ebb and flow setup in a 3' by 3' tray with a res that can hold 49 gallons... I will be using a 1000 watt hps lamp for most of the grow. Perfect grow room as far as temperature and air flow go. First, can i get away with 25 gallons in the res. Second, can I follow the GH Flora Series Keep it Simple Recirculating Program at recommended strength? It's an 8 week program from seedling to ripen. Third, I'm not close to a natural spring or creek so i have to use tap water. Will this be ok to use? Using 6" net pots with hydroton and growdan cubes for the clones. Any thoughts or responses will be very appreciated. Leaving soil because i'm tired of the mess and buggies and all that noise. squawk squawk...
