Thought I'd show my method for growing U. nelumbifolia, since I've had a few requests for info.
Nothing special really, just a couple 5 gallon buckets. The orange one has some holes drilled in the bottom. The black one is for holding RO water.
The media is pure live LFS. The plant grows in the orange bucket, sending roots/bladders into the black water basin below.
Growing in the corner of the HL greenhouse.. it flowers non-stop year round for me.
