Hey everyone! I'm new to these forums and in the few hours I've been here I've found so much useful info, it's amazing. I've been growing CPs for years now, but I guess you could say I've never really gotten it right. This year is the first time I'm trying to grow my plants in a terrarium with artificial light (they have been on a window sill in the past). I managed to find an 18 inch reptile flourescent light for my 5 gallon tank. On the box it says it gives off both UVB and UVA, and the guy at the reptile shop said the light was sufficient for plants (some of his customers have used them for less-then-legal growing). So I have this light on top of my terrarium, and after reading about putting foil along the sides for light retention, I did that. I also have water in the bottom of the terrarium (my plants are all in pots standing in it) but until today I didn't realize that the bottled water I'm using probably isn't distilled. I think this is part of the reason my plants aren't doing so hot. Many of their leaves are turning black, even the new ones.
So, my questions are: Do you think that my light will work for CPs? If not, what are some good alternatives? Also, as far as humidity goes, should I leave the top open?
It's really nice to be here and I think all of you for your help in advance!
