You really have a great system set up indoors. The previous failure may have been due to poor quality soil. Other than that, could the ambient temperature be important? If the ambient temperature is important, I assume you will also set up a heating system inside. I hope the plants germinate as soon as possible.
Ah thanks.. I may need to get some heating pads for the pots when using LEDs. But when the big lights are on, the tent stays around 80-90F which is great for them.
