This DIY grow tent has a few benefits. My aerogarden is in my small apartment so the light is intense at night. I’ll probably cutout one side of the box and add a mesh film similar to this one on Amazon. Then put the mesh side facing (but not touching) a wall and put a small fan on my plants to improve air circulation. It helps plants grow quicker. It also prevents bugs and cats from getting into my plants.
As my plants grow and I have to raise the light I’ll probably look into finding a taller box. https://www.amazon.com/aerogarden-Harvest-Hydroponics-Observation-Growing/dp/B09MK3RXKK
Saw this on Amazon specifically for the Aerogarden Harvest:

Have not tried it but looks like a good option. You could also DIY something with reflective material on the inside and and cardboard on outer.
