Ok, well I would look it up, can't remember who did the write up on it.
I put a little root stimulator, and cal-mag in the water, then ph it to 5.7.
Soak the cube for a few mins shake out excess water, drop the seed in the hole rip a
Small piece of the rooter to cove the hole with, and let them go.
Make sure that the plug isn't to tight of a fit so they can pop through.
The mistake I made my first time was I messed with it to much.
Check out my journal.
