ok they are frosty just not sticky as they could be, mind u ive 650 watts belting down on it and its about 90 degrees.. doubt that helps. i think its fert locked too.. i added the food i knocked up yesterday anyway and i do flush with plain sometimes til it runs clear. Im growin in a record box basically,, square foot and a half all round. my water is always a fair green colour wen i test it so i thought ph shudnt be a prob.. but then i dont get into microscopic detail.. how do i test coir for ph? wat about epsom salts to fix it? i hav some of that, i heard that corrects ph,, in soil.
