Sorry just saw this!
I only clone in rockwool. I soak my cubes in the following per 5 gallons:
1 tsp rapid start
4 tablespoons
clonex
1 tablespoon bleach
pH to 5.5
I let them soak in that preferably overnight.
I use a mondi clone tray and I use the
grodan orange plastic insert for the tray. This keeps the cubes off the bottom of the tray. I fill the tray with some tap water, about 1/4 inch.
I shake the cubes with one downward motion to remove some of the water so that they are not saturated. Then I fill the orange plastic holder every other row so the cuts arent too overcrowded. This method will fit 42 cuts to a tray.
I put them under a t-5 fixture but I only use one philips bulb in it, instead of 4 bulbs. 3500 K you can but it at home depot. It's a way better spectrum for rooting than the spectralux blue t-5s that come with most hydro store bought fixtures.
I use
dip n grow. fill the cup up halfway with tap after adding the
dip n grow to the concentrate line. Soak for 20 seconds and place in the wool. Put the dome on with both vents fully open and dont water until the cubes are almost dry. You should already have roots by then if you are lucky!
