Hey afroman35, Im in the same sitc as you. This is my first grow/dwcgrow and cant get clones. Figured I'ld lend a hand.
I started 5/21/10, last Fri. I placed my beans in a cup with h2o and covered it; placed it in a dark place. Waited 8 hrs poked them down into the water, the ones that sank can be placed into the medium you choose right then. I waited until they crack while at the botton of the glass before puting them in rocwool, might take 12-24 hrs to crack and show some white.
Before you put your seeds in the rocwool, seriously soke/submerge the rocwool in 5.2-5.5 ph h20 for like 30 secs then very very gently squeeze the top of the rocwool so the excess h2o drips out the bottom - repeat 2 or 3 times. Brand new rocwools natural ph is like 8.5, ouch! Try not to butcher the cubes like I did. I used like 2 for practice/recked them
.
Its now 5/27/10 Thurs. and I have 2/3 beans that I placed in the cup are now an inch tall with 4 sets of leaves (2 are seed leaves). As soon as I put them in the cubes they went under lights - 18/6 schedule with 6500k flouros. So far so good. Hope this helps. I will be watchn lets help each other out on this!
