IF using the SuperThrive crap (editorial opinion ), only use ONE DROP per gallon ... no kidding, it IS that concentrated, more can kill your seedlings ... secondly, cut your lights back, in brightness, not hours ... just use a single cfl or something like that ... without bright light, the plant can focus on root-building ... when the roots start appearing, you can bring the lights back up ... this seed-starting log I made, is also beneficial to cloning, in some instances - http://boards.cannabis.com/basic-gro...ml#post1967488 ... I really like the Rapid-Rooter plugs, and my bubbler setup ... they are excellent for cloning :thumbsup: ... happy gardening :smokin:
