are you talking about the rapid rooter plugs? if so, i'd wait until you can see roots emerging from the plug. it should only take about 1-2 weeks. remember, 1/4 strength nutes at first!
GoldenGraham84 Reviewed by GoldenGraham84 on . Ebb and Flow Water Schedule I have a 3x4 foot growing tray, filled with hydrotin and rock wool cubes. I was wondering how many times a day i should have my tray flooded? Also how long should it stay flooded each time? Thanks :rasta: Rating: 5
