personally, i've eliminated rockwool from my garden almost entirely.
i still germinate my seeds in rockwool because i've had 99.9% pop.

anyway, i built myself a bubble cloner that i put 2 drops of Superthrive into
and, like 7 days later, i get roots. it usually takes about 2 weeks to get a
solid little root system established and ready for transplant.

when they are ready, i just put them into pots filled with hydroton.
like this.

lol, justanother2cents, fwiw
justanotherbozo Reviewed by justanotherbozo on . Alternatives to Rockwool I have been using rockwool for two years now for my clippings. My problems with using rockwool is that the cubes dry out quickly requireing ongoing watering and it has been taking two weeks or more for roots to show. Temps are in the high 70's to low 80's and humidity is fine. They sit under T5's in their dome for three days and the dome is removed and they get misting every second day. My question is this.... What do you use and what sort of results do you get? Suggestions, and Rating: 5
