No Title
Howdy Tat6870, I soaked the rockwool cubes overnight in 5.0-5.5 pH'ed water. I do not germinate my seeds directly in the cubes now. I use the paper towel method now. I fold a paper towel into an aluminum pan, put enough pH'ed water (5.5-5.0) to come up to the top of the towel, place my seeds on the towel and cover all with plastic wrap and aluminum foil. Set the pan in a warm (80°-90°F) and wait. This allows me to see which sprout (and when) instead of waiting and guessing. When the seeds sprout, I transfer them to the previously soaked rockwool cubes (with a little rooting gel in the holes) and into the net pots.
Good luck with Your grow.
P.S.
Here's a photo of what I mean.
