I'm slowly thinking about the dormancy period of my plants, in particular, my collection of Sarrs. I had some limited success leaving them on a sunny but cold windowsill last year, but when the time came for some fairly active growth (in Feb.), the sun's orientation had changed, leaving them without adequate light. Being in a ground floor app., I had no other suitably sunny window at that time of year.
I'm considering getting MH or HPS lights, and setting them up in a large closet. I would fabricate some kind of temporary cover or terrarium to house the plants.
This would be my first time using such lights, and would appreciate any tips from someone who has used them before. I realize heat and humidity will be concerns, but what else should I need to know? How far away should the plants be from the lights? And just out of curiosity, could fluorescents be setup to do the trick?
The whole thing would only be necessary for a couple of months, until I can start putting the plants outside.
