Since you're having temp problems (I'm assuming you're talking about water temps) you'll probably want to get some Hydroguard to guard against pythium and some Hydrogen Peroxide to replace the dissolved oxygen your water cannot hold at the higher temps.

I wouldn't try to grow anything very big with it. It's a deep water culture system, and you'd be amazed at the speed of growth you can get if your air pump is pimp enough with a DWC system. I'm with Moose on the 12/12 thing. There's not enough room in the res for big roots, so you'll have to go...

One thing you may want to consider is to stay away from brands that are marketed specifically for cannabis, covertly or otherwise. Buying these nutrients is a dead givaway as to what you are growing. Examples would be B'cUZZ and Advanced Nutrients. But hey, level of risk is a personal choice...

Thanks guys! I lost a few more plants since my last post, but I think things have stabalized somewhat now (I hope), and I'm 6 weeks into flowering now, so hopefully I can nurse what's left along for another 2 weeks. The peroxide seems to be working great as far as pumping up the plants that were...

Aaaaaaaaahhhhhhh. Thanks Moose.

OK, I couldn't wait for a response because I am absolutely freaking out. I was going to go to the hydro place and get some 35% hydrogen peroxide, but they were closed for Memorial Day, so I went to the drugstore and got some 3%. I pulled the other 3 wilted and now dead plants, and of course the...

Thanks RaceFan. Can you be more specific on how to effectively and safely apply the hydrogen peroxide treatment? I was considering getting this pesticide called Gnatrol which is supposed to be safe to use, but I would much prefer not to have to resort to that if I can get rid of the larvea with...

I don't have a hyrdo thermometer, but I do have a heater with a thermometer in it that should keep the temp within aquarium range. It does not feel extra warm or anything... You think I might have a gnat larvae problem? Would I be able to see them on the roots?

OK, here's my setup: I've got a 6 trough NFT system with a 35-40 gallon resevior. Each trough holds 4 plants. I'm using 2 1000W HPS Hortilux lights in Vertazontal reflectors. Here's the deal: My plants have been flowering for 4 weeks. About 3 days ago, I noticed that the first plant in...

OK, I'm on my second round now and I've changed up a bit. I'm now using Ionic Bloom + Eco Bloom and a house-brand "body builder" silicon/potassium suppliment, which I also used in the veg stage. I'm sold on using a silicon suppliment now. My plants look much healthier and sturdier this time...

I agree about the PH being too high. The 6.5-6.7 range is less than optimum for marijuana. You should try to keep it right around 6.0.

What say you? Anybody got a good before/after experience to relate?

Thanks guys. I'm putting them on a 20/4 cycle today. You got any info on the less than 12 hours of light final period I mentioned? Would 10/14 be too little light for the last 2 weeks or so, or is this just a bad idea alltogether?

You mean it creates a longer flowering cycle?

I know that veging with the lights on 24/7 achieves faster growth, and therefore gets you into the flowering stage sooner, but does anyone know if there are any disadvantages to veging 24/7 instead of on an 18/6 daily cycle? Also, I have read that some varieties won't fully mature unless...
