3) For all other Grodan products- SOAK, FLUSH, then PLANT!
Soak in plain water (pH 5.5) for 1/2 an hour (longer if soaking granulate).






I was confused because they directions on grodan says that you don't need to soak the cubes that long. I followed the directions and don't hae thse crazy swings. My PH typical runs from 5.5 to 6.0

Great information +REP
4) Flush through with pH 5.5 water mixed with some plant food. Make sure the flushed water goes to waste. Then plant into your prepared Grodan block, slab, Grow-Cubes™, or granulate!

DO NOT SQUEEZE the cubes or blocks. They are designed for the perfect air/water ratio. When you squeeze the product you may ruin the good structure.
