Sorry I scrapped that project. It's too hard to get enough nutrients without harming the fish. The fish did seem happy but seemed a bit small. I put the fish in a bigger tank where i'm sure he liked the extra room. He was king shit in the tank and liked to hide in this decoration. other fish would try to stop by and buy dope off him but he would get all pissed off, flair his gills, and chase them away. He lived a happy life but died from a lengthy battle with ick which came from other fish that were added.
Cloning this works amazing. I had a friend cut a clone and put it in one of those small rockwool plugs. then it was placed in a net pot. there was a perfect opening by the filter on my aquarium so i stick it in there. I put a small desk lamp above it on 24/7. It had no problem at

Also you can drop seeds in an aquarium and they will sprout. sometime the seeds float and other times they stay low. I've seen most sprout no problem either way. Once they sprout they only live so long though and need transplanting.
