I want to grow large cacti, see my previous question. So I start with small plants and to keep them growing in winter time I want to give them LED (special grow) light.
I was wondering about the best light periods for the small young plants. I am interested in finding the best daily light period (how many hours per day?), and as well on when to start giving them artificial light (which months?). I was thinking of starting to put them under a light from November till February? Does that seem right?
I live in the Netherlands (latitude 52). I hope anyone can share his/her experience with indoor light regimes?
