Can you show us a picture of your set up and how far the lights area above the plants? What kind of lights?

Mike

They are these lights off amazon and are 12inches above the plants

Ugh I cannot get the photos to upload I will try again later

12" above plants is way too far. You need to lower them, at this point they make no difference at all. Amazon say 20-30cm (7.8"-11.8"), and I believe that is too far. I have lights as close as approx. 10cm (4") - depends on plants. Start lowering them slowly in order for plants to acclimatize to better light. It doesn't matter where the window is and facing (I keep many succulents in windowless basement space and lights are on about 12hrs), supplemental lighting supply enough light if used correctly.

You didn't answer question: what plants?

What kind of media are they potted in? Are there drainage holes in containers?

What are the plants that are ..."almost doing better and not stretching"...?

The light is driven by USB which is maybe 2.5W or less. As the others have mentioned, with these lights they need to be very close to help improve your growing.

For reference, I'm using 12W LED lights and they are maybe 6" or so away from my plants.

oh wow thank you so much guys all of this is very helpful information!
