we were asked this i believe a bit earlier in this post, id suggest looking at the system that grower had mentioned to see if its the same.. wicking from the bottom with our system isn't something i personally recommend. As i stated with then a drip top feed is fine but keeping the hot soil soaked isn't going to be beneficial. you want your media to properly dry especially with organic growing, the media needs to properly breath and wicking keeps the media too moist generally
