I have been very skeptical about LED for years now, but after reading through several LED grows on here by people that know what they are doing, it really does produce when you use high quality LED's!
There is a guy on here getting great results with his Vipar and another using the Solarstorm. They just keep getting better! Do an RIU search for VIPAR and Solarstorm and see what is out there. For me 2K is about what a good HID+AC+Chiller+Edison would cost me for one grow. For that kind of money you can get some killer LED setups.
On my next grow I want to try a shorter veg and concetrate the plant in a 2 foot circle to see what I can get this 90 watt LED to do. Right now I do not know how much I have messed things up with nutes, CFLs, topping, landrace sativa... I need to get a PO Kush clone and give it a try!
What the hell is wrong now? Where's my user panel?
