appropriate lighting


Question
QUESTION: Dear Jeff,

   I have 1 nepenthes(poi dog), 4 sundews(capensis var., aliciae multifida), and 1 pinguicula (gina). I grow them with Primo water and I grow them on an east window and grow them about 12 inches away from a 18watt, 120 vac, 60z 260ma compact fluorescent light. The sundews are pale and gangly and the nepenthes hasn't grown pitchers these past 2 years, so I am starting to question the lighting for my plants. I was considering to buy this light:
https://www.1000bulbs.com/product/1601/FC40-FEIS40W27.html?utm_source=SmartFeedGoogleBase&utm_medium=Shopping&utm_term=FC40-FEIS40W27&utm_content=2700K+-+150+Watt+Equal+Compact+Fluorescents&utm_campaign=SmartFeedGoogleBaseShopping&gclid=CjwKEAjw1MSvBRDj2IyP-o7PygsSJAC_6zodZyPxnuRIBUi5fOTCwb9270whRFOcbQkraj6ZbFEwcBoC7gfw_wcB. Please tell me if this will be right for my carnivorous plants.

         Thank you
         David

ANSWER: Hi David,

The signs your plants are showing definitely sound like too low light levels.  If you're going to use an CFL, use one of these:  https://www.1000bulbs.com/category/150-watt-equal-compact-fluorescents-5000K/  It's a much better spectral output.

Since you have several plants, here's a much more efficient way to do this.  Use a simple two-tube shoplight type fixture with either T-12 or T-8, cool-white tubes.  If you can find a way to hang it you'll have much more plant growing space.  They also make some T-5 type units like this now that are much stronger light output.  Here's an example of the more common type:  http://www.homedepot.com/p/Lithonia-Lighting-All-Season-4-ft-2-Light-Grey-T8-Str

Good Growing!

QUESTION: Thank you for your information! I bought some T12 40 watt flourescent lights. I couldn't find a way to hang them though. So I put the light fixture on the side and I was wondering if light coming in sideways is fine.

         Thank you,
         David

ANSWER: Hi David,

Do you like your plants growing sideways?  That's what will happen if you illuminate them from the side.  Plants do what's known as phototropism; the bend toward light.

If you could send me a photo or two of the type of light you have and your growing area I might be able to give you some better suggestions on how to get the light over your plants.

Good Growing!

QUESTION: Here is my light fixture.

Answer
Hi David,

You just need to find a way that works for you to suspend the light over the plants.  That can be done with longer chains from the ceiling, a small frame you could build or purchase, or even blocking the light up with bricks or other objects.  I've also used small shelving units for this purpose.

Good Growing!
