The hydroponic system I mentioned, wasn't made specifically for marijuana. It don't look like the grow sites are 15 inches apart, but the pipes are not directly over the tub. It could be scaled for any size plants. And cheap to build.
Interesting idea for someone wanting to grow small plants for sure.
That was my original plan...the problem is, I live in southern Spain and apparently there are no buckets with lids here. I can't even find a plastic tote that isn't see-thru. :/
Buy a Ice Chest ....then your reservoir temps will stay at desired temps.
Styrofoam painted black might work also... Styrofoam ice chests are cheaper.
You could make one......... but thats a whole nother thread good luck bro!!
haha yeah it's kind of ridiculous here. I started out wanting to do a dutch pot system but decided that finding a bucket with lid would be easier after looking 2 weeks for dutch pots. Apparently I was wrong. Best I could find were Mayo buckets (1gal aprox) without lids.. Ice chests are about €50 because of tourists and every storage tote within 50 miles of me is clear heh Just my luck eh?Also the flip top lid hinges can be cut so that you can remove the lid easily. the only hard part is going to be cutting the holes in the lid and getting net pot of about 6inches. If you can find a bucket lid, I dont know where the hell your gonna find a net pot.......
