Rockwool Germ and Rootstim??

Hey guys, I‘m starting my grow and I‘m about to soak my rockwool cubes for the second time (5.5 PH water only the first time) and I wanted to know how much root stimulator I would need?

Well of course you won‘t know the strength of my stimulator, so rather, can too much damage the seedlings?

Also, do you recommend the paper towel method first and then drop them into the rockwool or straight into the rockwool, but won‘t the rootstim hurt the seeds?

Any info on root stimulants and seedlings/seeds would be great and the amount to be used.

As far as the rootstimulants I don't know much about it never ever used it before, but I definetly recommend doing the paper towel method first and then drop the seeds into the rockwool

I start all my beans in paper towel. More for just a good soaking. Some sprout some dont but I only leave them in for a day. Then they go into my cubes. My seedlings dont get anything as far as nutes or stimulants until the 3rd week. Even then they only get a little thrive alive b-1 red. Used for cuttings and transplanting usually but 3 week old seedlings seem to love it. Never used any other stimulants though. Root structure isnt usually strong enough for much.
