I am currently new at this whole growing scene and want to make sure i focus on the most important things. Me and my friend built our own bubbleponics system with foamcor, a 12 gallon storage bin, airstones, 150 watt flourescent fan (with venitaltion) and plenty of nutrients. we have the grow room then the budding room. Our budding room is 22"/25"/41". What is maximum plants i can fit for optimum growth and how important is pH. Also i need a cheap lighting system for the grow room and a way to get CO2 involved. Any suggestions.

PH is VERY important. If its off one way or other it will cause nutrient lock, where the plant will not uptake nutrients. Keep it about 5.5 to 6.5 for best results.

5.2 to 5.8 is what you want anything higher is not good and can cause root rot

I have been hearing lot about T5 bulbs you may want to give them a try. Garden Known has also had a lot of luck with CFL bulbs So you may want to put a post in to him.

I dont think you can use co2 and cfls, correct me if i am wrong. You need more lights. Got any pics?

surely you mean it can cause lock-out? Which it doesn't, you're fine in DWC up to 6.2... although I'm not saying this is good... it is doable. The plants will absorb nutrients better in the 5.2-5.8 range. In fact, there is evidennce now to suggest that even 5.8 might be too high, and out of the optimum range to uptake nutrients.

In DWC your roots will rot if you allow light onto them, or the res' is too low... or too warm. Plants prefer a colder res, as this helps in the uptake of nutrients too. in fact the temp' of the res is more important than the temp' around the plant...

Here's the money shot for grow lights! Theyre actually really inexpensive for a 5 pack, which supposedly equals a 400w HPS. Another benefit is that they have extremely low heat output.

They're new, and I would love to see someone take a stab at a grow op with them.

I'm dutchmastr partner in crimw has anyone trien these new LED's because if there legitn we'd rathe get thm then the HID's(lower the elelctricity bill) Anyobe thry them yet???

I've put a fair bit of thought into light... and I can tell you (as far as my logic tells me) that light spectrum is not the only important aspect to growing weed, but also light intensity. The more intense the light the more potent your plant will be.

LED's are very similar to fluoro's in that they put out very little intensity. You might get it to grow, might even one day pull a decent yield, but it'll never be as potent as the same plant grown under a HID.
