Yo How should I construct a circuit (for a micro grow-1 plant) for an LED grow light, but using a Joule thief system (powered by batteries) to grow this plant? I had a look at this tutorial: LED Grow Light using Joule Thief Battery Power in a Wick Gardening Container for CHEAP! I'm gonna try growing with different lighting, for eg. using LEDs for vegetative then switching to CFLs for flowering, and vice versa. I'll post a Journal after I'm done with results, I just need help with the circuit. I want to drive the LEDs as much as possible. I will be using full (not depleted) batteries. And if I can, more than 1. All help appreciated!
