Happy Frog Soil for seedlings?

To prevent shock I am considering using the plastic cup technique with happy frog soil (the soil I use for mature plants) to germinate seeds. However I think their is a small amount of organic fertilizer in the soil. Any soil growers have any advice on how this might work out?

Thanks for the help!

for what its worth roots organic, and happy frog are the two most recommended soil mixes to use. I still like adding perlite as i believe MJ wants a better draining soil.
id add only some perlite to it to allow for the better drainage. stay off the nutes for a week or two. see how they react.




EDIT: yeah i must have skipped right over the germinating seeds part, i only saw seedlings...Paper towel method always works for me for germinating. I hear straight perlite will work also...

Should work transplanting into, just not for starting seeds.

I agree with uno and moon. perlite gives good air and moisture control. Try avoiding over nute's, less nutes=better control, too much nutes=out of control.

yeah made the nute mistake once already

I have been using rockwool to sprout though (after taproot comes out), and as soon as a transplant (clones or sprouts) the shock is immense. My clones teeter on the brink of death before recovering. So I'm looking for a way to reduce the shock their exposed to.

I figured maybe I could germinate using the traditional methods. In a jar full of water overnight till they sink, then after they sink on a heat mat with some paper towel. Then once they need to be planted instead of using rockwool, and making them undergo the shock later, I could use happy frog soil with maybe a 50/50 mix of vermiculite. That way when they finally get planted into pots they are already used to the soil as apposed to adjusting from rockwool or peat pellots.

Less shock = Happier plants?
