I say no. Because the soil contains nutes - and if it is feeding up to 9 months then its going to be slow release nutes. Growing even for two weeks IMHO is not a good idea because even when you transplant, the root ball will still contain these slow release fertilizers. If these dont burn your plants right away, they may mess with your feeding when that begins in a few weeks. Seedlings need no nutes until at least the fifth set of leaves, from what I understand. This is what I did, and although I am only on my first grow, I am almost finished and I had relatively few problems. I really liked the soil I used - I used a perlite, light seedling mix for the seedlings, then I switched to Fox Farm's Happy Frog Soil. I also understand (from what people have said) that pro-mix (which is readily available at the the depot, or wally world) is also able to be used. If you want happy frog or any other fox farms stuff, I do believe your best bet would be a hydroponics store. Hope this helped ya bud, just don't want anything to go wrong for ya ! :rastasmoke:
