My current grow should be done in 5-6 weeks. I might want to try my 5 gal bucket DWC again for my next grow and if I do I'm probably going to try out the ph perfect again myself. The only time I did a grow with my DWC bucket was with a LED light, a 180 watt jumbo ufo from pro source world wide. The plant just grew tall with lots of stretch and didn't bud very well. The plant grew so tall that it was up past the led light and the light was hanging as high as I could get it. The leaves even got fried by the led light which was one of the things specifically listed that the led lighting was not even supposed to be able to do. The light was advertised as supposed to give better trichomes because the led light is low heat and can't burn the plants. But somehow I was able to burn my leaves to a crisp. From that grow I was a bit turned off by led lighting, that and I hate the color of the light. My led light always left me with a green hue in my vision after looking at my plants. It was better suited for vegging in my opinion, but even 100 watts of T5 can veg even better then the led did. My light might work fine, in the right setup. I just haven't really used it since then. Nor have I used my DWC bucket with a better lighting system. Now that I'm setup with 600 watts hps and have a few grows under my belt with hid, I think it might be time to try out that DWC again. Someone told me that the DWC is too much horse power for the LED light I was using to keep up and that's why it stretched so bad, and I also got slime on the roots which didn't help. What I really might do is take a monster crop cutting from my plants in bloom now, and re veg the cutting, then use that as my plant for the DWC, use ph perfect and see how things work with a better lighting system. I really do think advanced nutes has some great products. If I use ph perfect I don't think I have to chase the ph. Sorry a little off topic but that's what I'm thinking about doing, and a brief explanation about my bad experience with led.
