If you can, go to an Agway dealer instead and get the composted cow manure with humus and mix it 30-50% with perlite.

The manure/humus is only $2.50 for 40lbs and pH buffered beautifully.

The perlite is I think $17 for a bag the size of ME. lol it's HUGE. You can get smaller ones too obviously.

I use this soil from seed to harvest. You can add different things at different life stages too if you like, but you don't have to. For example you can add a little bone meal if you are potting into flower.
