Id say it depends on how the rest of the enviroment is. Make some homemade co2 bottles and lower the lights that will make them hungry as hell. In return fast growth!I've did 3 grows in DWC using Dutch Passion seeds and Fox Farms complete line of nutes. I'm extremely happy with the results. Getting ready to start my fourth grow tomorrow. Be aware though that you really have to back down the nutes. I use somewhere in the neighborhood of 20-25% of what Fox Farms recommends. Anything more and the plants burn and start spotting.
