did you soak the rock wool before the grow?I'm starting some seeds,in 1"rock wool cubes....I spary the cubes,with water,to keep them moist,the seeds are growing,but the tips of the roots die,is this normal,or should i spray a mist of water on the roots too....all advice welcome
I plan on putting them in ebb & flow..they not even an inch tall yet,they just have that main root,so i still have them under light,i'm just trying to get them to have a good root system,before i put them in ebb & flood,but like i sayed,they growing but,when i look under them,the root tips turn brown or die,i was thinking it was air....And yes i soaked the cubes, 5.5 ph.
