how often should u flush? should u just flush towards the end of the grow? should u flush every other week? or every month? just a question i been wondering.
Hi uneek, I'm in coco, Botanicare, Ready Gro, aeration variety with about 25% pearlite. I flush monthly after the start of nutes & I make sure there is plenty of run off from my watering. At the end of flower I run about a couple of gallons of water a day through my 2.5 gal superroots airpots for the seven to ten day flush period. Works for me. Cheers
What are you growing in ?????? the above post mentions he grows in coco which has a shit load of phos so he has to flush but if your soil grower Flushing should be done as a last resort from either nutrient burn or vegging so long that salt build up has occured flushing can lead to a world of problems from yellowing to actual osmosis issues
