I have some questions regarding the lighting for my pepper seedlings. To start, let me say this is my first year gardening and I went about a few things the wrong way and am now trying to correct those mistakes as I learn more. I initially got some bad info that I could grow my seeds in a window sill. After I started doing this, I noticed that the seedlings were getting very "leggy" and were stretching for the light (some fell over and died), even though they were in a very sunny, south-facing window. Now, I have purchased two 30 watt LED grow lights from Amazon (link) and have arranged them around the seedlings in such a way that is shown in the attached images.
I leave the lights on for 12 hours a day and water enough to keep them moist. The seedlings are still very thin as of right now, but it has only been a few days since I started using the lights. Will this setup be sufficient to grow them until I transplant outside, or will I need to make adjustments?
