you grow some seriously good looking shit.... respect
i tried the wilma with clay pebbles using a 15 minute feed 3 times a day, like a top feed flood. IT grow really well with the oxygenated roots. Are u using just coco,.? im sure it tastes better with coco... I think the wilma has its main benefit for recirculating systems .
I normally just put a pump on a time witha bit of hose and plug in drippers, that way i can keep the res in cooler place that will ensure it doesnt get too warm.
peace..
fucking awesome collection btw
