Question

Plant setup  

Wilting Drosera Int.   Here's what you requested:
 My drosera Intermedia is in a small back bathroom in a plastic tray of rainwater.  Its usually around 70 degrees with about 68% humidity. The room has no windows, but I have a 6500K and a 5000K daylight spectrum CFL on them about 16 hrs per day. Other small plants do fine here. The plant is in peat. I had just bought it and thought I would harden it off first. Would it help to cut it back? Here is a picture of the setup as well as the plant in question.

Answer
Based on your questions, I will assume you are talking about the wilting Drosera in the second photo. First, if you just bought the plant 3 weeks ago, you should contact the original grower immediately. Only that grower can confirm its original growing conditions.  He may also guarantee the plant for 30 days.  That should be your first step.

What you do next depends on what he says.  If he's going to replace it, then just chuck the plant when you get the replacement.  Sometimes it's not worth the effort to salvage a plant that far gone.

You should also clarify whether or not this is a tropical variety of Drosera intermedia.  If it's a temperate variety, the plant might be going dormant.  If it's a tropical variety, there may be something pathogenic in the soil.  Again, you should check with the original grower regarding this information.

So I can't help you much with only the information you provided.  Cutting off the dead leaves is always a good thing to do because that will reduce the risk of mold and fungus.  However, whether you should chuck the plant depends if the plant is actually going dormant or if it's diseased.  Your photo of the wilting plant is also blurry, which doesn't help me very much.

So first contact the original grower to figure out the variety of intermedia you have, temperate or tropical.  Then ask the grower about the original growing conditions and for his advice on what you should do for the plant.  After that, if you need further assistance, write back as a follow-up.  Please include a clear photograph of the plant and the wattage of the lights you're using.

Good growing!
