So I have had this dripper in this rockwool medium for its whole life (3 1/2 weeks), and i was just wondering if this was bad. the rockwool is getting this dark spots where the dripper is and its the same in the whole garden. Any help? Here are some pics.
Ok, so this is my first time growing weed. I chose to do it from a drip system i made at home. I used a bus tub for the tray and made some holes for drainage, bought some flouresents and nutrients and some more little things and just chose the best seeds that i had and began growing.:mrgreen...
