It's been asked before in the past but quality does seem to change with these. What is everybody using to grow their pereskiopsis and cacti seedlings under lights? LED? CFL? Fluro T8 or T5s?
I have a square meter I would like to light artificially, how many watts and what type of light would you use for this? I currently have 2x 35w and 1x 24w CFL cool daylight spectrum to work with. Would this be sufficient? Also, does anyone have experience heating things with a heating cable? Just interested in safety with one of these compared to regular heating mats.
