ive just read some where that i shud just place them in the rockwool, then into my propagator, keeping it sealed and heated and place in the shade until it pops out. if i do use the light, how far is a gd distance for a 400 watt lite for this job, considering i dont want to dry the cubes, i have to leave them for 9 hours a day. thanks again
arthurjob Reviewed by arthurjob on . water problem hi, ive just recieved my gro tank 205 thru the post. the problem i got is the instructions say to soak the rockwool cubes over night in ph 5.5 - 5.8ph water. the supplied ph graph only shows up2 6!!! how am i meant to go lower. also, the measuring beaker supplied doesnt have any mls on the side and it doesnt say how much the beaker holds lol. i tried a little tap water to 2 drops of ragent or watever its called and it came out the worst (highest on the chart) which is 7.6. wud i be better using Rating: 5
