rockwool SBS propagation tray

I read the cannibis grow bible and I need to to find the best rockwool SBS propagation tray I can get, could someone send me a link or something. I just bought fem seeds from attitude but there is only one per pack, no room for error. I am looking for something with a heating element that can keep a constant temp and has a cover for future cloning. Thanks guys. I really do not want to have to resort to using Gibberellic Acid-3.

Hey man do a bit o reading, the grow bible is good and all but the advise here on RIU is better and more up to date.
Welcome to RIU btw.

Happy reading, it's long but VERY informative.

Are you saying that a rockwool SBS propagation tray would not be the best method because it is out of date?

no not at all,
there are several ways, others make work better for you.
Rockwool is a great way to start clones and seedlings, I use it, not with a prop tray or anything tho...
