Dirt bag needs to read the tou. if the insults and trolling, aren't edited, ill be cleaning up, by deleting the whole posts.
regarding coco. you can reuse coco multiple times. as long as you have no medium based pest infestation you can reuse it at least 3 runs, have experimented with up to 7 runs in the same coco slabs. nowadays i will not use the slabs more then 4 times. you just have to maintain it properly by flushing it here and there if it gets too salty. to be honest when saw your trays i was thinking how easy it be for you to go to automated coco slabs with that base set up. just need some drip lines to hook to your pump instead of flooding the table you just drip feed till a bit of run off, from 3 to 7 times a day. i like 4 watering during lights on period and no watering during lights off period, but that side of it is very much up to you. seen coco rock with just a plain 30 lt pot full of coco set on the floor, guy was watering by hand once a day, gets great results and maintains a much lower plant count then i do. but you will need to lower the table as low as it can go, right down to the tank, cause they will stretch like hell in the first 3 weeks of 12/12
