Thanks Chinaman I'll check it out . I've been hearin a lot lately about how flushing doesn't do anything for the plant. Also, these same people are sayin that drying and curing is how you can bring out the max taste and smells. DUH !
Photoperiods stop taking in nutrients through the roots in water grows no matter what you feed them. I flush because I dont want to waste the nutrients since they wont be used anyway, but I do notice the Brix goes up if you flush so it should taste a little better and store for a lot longer. Bottom line for me is it doesn't hurt anything in a water grow.
