GRIM REEFER. i believe it does contain perlite. and needs no help with drainage. my pots drain in llike 5 secs.
also they say, u dont need to fertilize plants for 30 days :} And I didnt and mine grew pretty good. towards the end of veg, i gave them minor ammounts of ferts, but they really didnt need em.

heres a link to ingrediants i think

bob bobbinson Reviewed by bob bobbinson on . What soils NOT to use? OK, so Ive got a few more Lowryders on the grow and also a White Rhino. Theyre under a 250w HPS, and considering the Lows grow a lot faster than the WR... theyre a helluva lot smaller (considering one is the same age as the WR). Now the only thing I can put this down to is the soil Im using, because before theyve been fine - good enough to pollinate a female for seeds, so that must be something. Buster was having some problems with Lowryders aswell, though I think that was down to germination. Rating: 5
