PH?
And it sounds like your germinating them in too much water.ket it start to dry out a bit once the seed cracks.Like you would with soil...water let dry water...but you can't let it get too dry or the seed will die.Let dry to a damp feel not dry.
The tap roots should grow to about 3/4 s of an inch then put in rockwool and wait a couple dayz.
J DOG 6000 Reviewed by J DOG 6000 on . stems turn purple then die greetings all,,,,, I am a newbie and this is my first attempt at a grow. been having terrible success in gettings seeds to germinate.... I have a germinator with the heat pad and dome, using rockwool cubes. out of 15 seeds I have gotten 3 to sprout. on most, the seed cracked and the taproot was evident but but didn't get any longer than a quarter of an inch and didn't make it to the top of the rockwool......... The 3 that did sprout seem to be doing fine for the first 3-5 days. The first set Rating: 5
