Maybe good for supplemental and side lighting....? Good for the plants being able to touch the whole fixture and light. Not good for projecting the light into your plants.

no penetration I hear

Ok. My plans were gonna be for my clone room as i am sharing with my veg room as of now and needing the extra room in there lol.

If anyone has used these chime in, please n ty!
