I live in the UK and have been growing some Carolina Reapers from seed using Hydroponics..It's been going pretty well and I have some small plants and larger ones. Here is a larger one sitting on my window ledge:
In the past I haven't had much luck using lights so I was reticent putting my best plants under the lights; so I put a couple of younger ones under two different LEDs and both within a day starting smelling sour and died pretty much straight away (very sad):
I put my hand just above the plant when the LED was on and it was slightly warm if anything...I was hoping to get some fruit going during the winter but instead have dead plants. The others I'm over wintering giving them kick start for summer. So my question is what am I doing wrong?
