    I would still keep it a couple of feet away at first. I kept mine 2 1/2-3 feet away at first.

    I was having problems, then i got a Hydrofarm Germination with heat pad for $20 on Amazon, now I only soak the Rockwool for about 2 hours, 3-4 days and all is perfect in a dark room in the germination station and you have beauties every time

    How far away are your lights? They look like they are stretching.

    That is too far, get them down to 2". They won't stretch so much in between nodes.

    Yes. yours are also stretching. This can be a common problem using HID lights for seedlings. I use flouros when they are that young. The problem with the HIDs is if you get them close enough to not cause a stretch you will burn them up. I keep flouros a couple inches away and the plant doesn't stretch. After the root ball is well established I slowly bring them toward the MH until they are happy..

    I dont see how a coty seedling can be stretching...? isnt stretching when the space between nodes is increased? I see no Nodes...

    4/20/2011 - UPDATE: the (3) seeds never sprouted. The one that did is doing fantastically. So, rockwool did not work for me to germinate seeds. My buddy Doug just germed 5 master kush seeds in rockwool. He told me they grew to approx 5 inches with the cotylodon leaves showing only and after three days they fell over and died. I have successfully cloned using rockwool, but that is the only use I have for it.
