Do you use a terrarium?

Night temperature drops

Saturday, September 25, 2010

I have been growing my plants on a reverse night/day schedule because my lights were blinding me during the day. I realized that this created the reverse temperature conditions, it was cooler during the "day" and warmer during the "night". I wasn't sure how big of an issue this was so I posed the question to the experts over at Sarracenia Northwest:

"Hi Adam,

You bring up a very good point.  We generally recommend nighttime temperature drops for highland Nepenthes because that's what they often experience in the wild.  However, it doesn't necessarily mean that the plants absolutely needs it to grow properly.  Overall, it depends on the species you're growing.  Ultra highland species tend to produce more pitchers with nighttime drops.  Other highland species, such as N. sanguinea, do fine without them.  

The point about growing these plants is always observing their growth and making necessary adjustments to the microclimate to achieve the growth you want.  So if you notice that the plants are not producing pitchers, then you may need to go back to daytime lighting to allow the temperature to drop at night.  That's what it essentially comes down to.  There's no hard and fast rule about growing in cultivation.  Our recommendations are starting points.  After that, it's a matter of fine tuning your growing conditions so your plants look their best."
