2 bags Fox Farms Ocean Forest
1 Bale
ProMix (HP) (BX) what have you...
1 Large bag of small-meduim coarseness perlite.
(some add lime/pH buffer of some sort to mix, some do not. all personal pref.)
^^
is a great mix that will go a long way to filling many holes. and isnt all THAT pricey beacuse the
ProMix is relatively cheap per bale and that bale can make 2 bags of
FFoF seem like 4. (without any adverse effect on soil or soils behaviour.)
also, home de-pot does sell black gold and "orchid mix" at all, or most, of their stores. Good soil for the price, as well. But the bags are usually smaller than the FF or
ProMix bales......
miracle grow works, in an absolute pinch, but you most likey wont be happy with the results, or, results could have been alot better.
imo, save the MG for the pretty flowers or anything else non MJ and vege related.
(just let it be known, if your purchasing true organic soils....gnats are a real possibility....ive got em from FF as well as cheaper soils. just a fact of life and honestly the fungus gnats are harmless other than flying up your nose when youre trying to breathe. :D)
if ya got more questions or want us all to expend on our opinions, just let us know.
