tea is pwnage , makes the single weakness DWC into nothing. DWC is great b/c it has its own resevoir. plants all require different nutes esp. diff stages of growth. the DIY grower can easily make a brewer and be very successful in DWC with no problems at all. the last problem in DWC is resevoir temps. these are kept down by other methods. the basics being keeping that nice open layer between the bucket and the canopy, allowing the heat to stay at the top of the room and not heat up the buckets.
