Just got back from the agway (farm/feed store) with ~8cuft of perlite for ~35bux. They have everything needed to grow start to finish (maybe sub out castings, and sub in composted manure/humus), and CHEAP.
For the stuff that I HAVE to have (fishing lures catch more fisherman than they do fish, lol) like crabshell, plant success, coco, bottles, ladybugs, room equip, etc... 4hydroponics.com (growco in MI) has great prices, and the shipping is free over $250. Plus if they have to ship something direct from a manufacturer, THEY pay to have it plain boxed.
