Lighting for D.Capensis


Question
I was wondering if I could grow a Capensis with a 26 watt and 13 watt bulb, please tell me how much watts are required for it. I am trying to grow it freom seed, and here it is 40-60 humidity, 60-75 F, 1/2 sphagnum, 1/2 peat, and going to grow it indoors with boiled water {cooled of course.} Texas is the place i live. Please send me a reply.

Hi Yoshi,

If the "bulbs" your talking about are compact fluorescent lights (CFL's) they will work fine.  It's best to use 6500K color temperature (Daylight) CFL's since those are closer to natural sunlight.  If your bulbs are incandescent bulbs, they will not work.  (If they get real hot when you have them on, they are incandescent.  CFL's will be warm, and have glass coils, but not real hot.)

Your soil mix is fine, although I prefer for sundews 1/2 peat moss to a rock ingredient like sand or perlite to give the media better drainage.

Your water may be a problem.  If you are talking about taking tap water and boiling it, all that does is kill bacteria, which isn't a problem for the plants anyway.  What you need for carnivorous plants is water that is low or free of minerals like calcium and magnesium.  Water heavy in those minerals (which is the case in most places in the U.S.) is referred to as "hard water".  It's an old urban legend that boiling removes minerals; it doesn't.  You need to use either rainwater, distilled water, or water purified by reverse osmosis.  There's also one filter pitcher that removes minerals.  It's called Zero Water.  It's the only one, however, that does that.  Brita, Pur and other don't.  

Purchasing a Zero Water pitcher can be helpful since not only will it take minerals out of the water for small quantities of water, but they include with the pitcher a TDS meter which you can use to test other water.  In general, if water is 50 parts per million or less in minerals, it is safe to use on carnivorous plants.

Good Growing!
