I’m using this one. https://www.amazon.com/gp/aw/d/B07NN6SVG6?psc=1&ref=ppx_pop_mob_b_asin_title

This seedling just showed its newest leaves two days ago. I took off the done (plastic bottle) yesterday. It's in a peat pod in cup of soil. I currently have a 9 watt GE LED Grow Bulb on it. The temp has been staying at a sensible 74 degrees F

Should I turn on that side lighting strip here? It's "cool" white and it gives off a little heat.

FWIW: I also have a 18w 1200 lumen CFL bulb that I can swap with that GE Bulb.

I have the exact same greenhouse. I use this grow light on the top shelf and these lights with these covers clipped onto the shelves

I used something similar to this but it does have pink and blue settings. I used white for 12 hours, can you tell me what to do for next time?
