No if you read sub cools revised super soil thread on the first page he says not to put seedlings or clones into this mix......he vegges for 60 days before transplanting into 7 gallon pots half filled with super soil.....some people have said they grow in super soil directly but most strains can't handle it......too hot...as far a veg nutes...there are many on the market....pureblend pro works good for me.....or aact teas....but most soils (like roots organic) will get you by with just water unless your containers are small.....I veg in 3/4 gallon pots.....at about 30 days or so give or take depending on strain I will have to give them a dose of nutes....if I veg in bigger containers I don't have to feed so early.....
