I don't know. I have never used LED's.
Your two grows are looking good.
When it comes to light and plants, things act a bit differently. Plants have some unusual properties that makes light interact in different ways, not unlike how some metamaterials act. I had good airflow, however I don't think it was the issue though more was likely needed. The problem I had was I was simply pushing too much power in such a tiny case. As light hits a plant, most of it is never absorbed, it's either reflected off or radiates back off the plant as heat. What I'm betting on was the plant itself was getting too hot from the bombardment of pure usable power it couldn't absorb and thus it turned itself into a krispy kritter.

These things happen. I was so busy focusing on one thing I totally neglected my favorite scientific laws of thermodynamics and as a result, you see the suffering I had to go through.

SWC Micro Grow Member for years, finally deciding to post, with a starting project - a converted A/V Workstation case (larger than your typical PC case) into a growing box. It takes up just over one square foot of floor space, and I have about 1.5 cubic feet of growing space inside. I am using a 6-quart container modified into an SWC container for two plants. For ventilation, I have a 120mm computer fan powered by a 12VDC wall-wart from some random electronic equipment. I am using an over-sized air pump Rating: 5
