I've always wanted a go at hydro,but things can go wrong very quickly if you don't spot any fuck ups coming lol.so I went with coco,piece of piss man lol.you can't over water in coco and if things look like they are going tits up,just chuck a few litres of ph'ed water through the pot.nice and easy.so you check your ph and ec levels every day? I check my run off once a week,if alls good I'm happy,if they not feeding,I give them a small rinse with ph'ed water,and lower feed slightly.everyones got their own way of doing stuff man,I just love growing weed lol
