Question
I've read through many Q&A threads regarding the king sundew, and a common tip I've come across is to make sure the plants are in an environment where nightly temps drop fairly significantly from 75-80 to 60-65.
In my setup, my regia is under a HID light and the temps get up to around 82-85 in the immediate area during the day. At night, when the light is off, I keep the house at 72 degrees.
Do you have any suggestions on what I could do, that wouldn't cost a fortune, to drop the temp in that immediate growing area by another 5-10 degrees at night? I suppose I'm specifically hoping you've come across some novel techniques you (or your customers) have used that do not require additional air conditioning expenses.
Thank you,
Tom
Hi Thomas,
There actually is. Pot the plant in a large, unglazed, terra-cotta pot. The terra-cotta has an evaporative cooling effect, so a small fan on the pot will help that. Also, water the plant with cold water at night before bed time. I'm assuming your house is air conditioned during the summer which will help with dropping the relative humidity.
A small window AC unit might be a consideration also, especially if you have highland Nepenthes in there too. The little 5-6,000 BTU units are not terribly expensive to operate.
Good Growing!
