I grow my plants under two 18 watt cool white fluorescent tubes 18 hours on 6 hours off. seeds are under one 18 watt light until they start to shoot then i move them to the 2 x 18 watt set up. lights are about 15cm above plants
I have just started adding Thidiazuron (TDZ) to my media for callus formation in nepenthes. I have been using BAP from the start and had some good results but nothing consistent. on reliable information i have changed my media for callus formation adding TDZ to it. I will add up dates on how things go.
