Razza, heres what I did. I was in a similar situation as you. I use promix. On day 1 of flush i took them into the bathroom and in the tub, i flushed them with about 2-3 gallons (2g pots) of water. I figured this rinsed all the fert out of the soilless mix. Then, for the remaining dys, i just watered them with a little more than usual amount of water. So, really, i only dealt with runoff once. Who knows if this is the right way, but my buds tasted just fine.
dusto2k3 Reviewed by dusto2k3 on . Flushing Hydro style? I am growing in SunShine #4 right now, a little over five weeks into flower. I know I have to flush for the last five to six days, and I am curious how much needs to be given to the plants? My bud sites are becoming a bit too heavy, so the plants are going to be tied to PVC pipes and unfortunately are not on a tray or anything like that right now. Trying to make some sense of what is going to be a tricky situation here shortly, due to the fact that I have no good drainage system. I guess Rating: 5
