This weekend I set up the winter gardening project, and moved some plants under the lights. This is an experiment. I'm using online resources from other folks who care for plants under LED lights.
At the moment I have a very crowded couple of trays under one metre of LED lights on a flexible ribbon or strip. The strip is designed to be a grow light, and has eight red for every blue LED, with 60 LED lights/metre. The light strip uses 12 Volt DC and draws approximately 14 watts. I have a second strip which I will need to install soon, give the amount or growth I've noticed in just 48 hours. I'm also making arrangements to purchase additional lighting; two more one metre strips, but with five red for each blue, and LEDs that are placed on a 0.5 metre solid metal strip.
As I said this is an experiment, I'm relying heavily on online resources to glean from the experiences of others.
My trays are a home to several dozen kale plants, half a dozen spinach plants and a variety of brassicas (Bok Choy and Chinese Cabbage).
