I have a strangely set up terrarium made of a 44 gallon pentagon. It has a hill at the back corner, and it slopes dramatically to the lower mound of dirt.
However, it is only lit with a 100w ebay cool white led panel and a 24w CFL bulb. I think this is not enough light, as my plants survive, buy barely get by because there is about 1.5ft from the lights to the lower tier of plants. Is this too little light?
P.S: the plants are slowly turning brown, or becoming green.
