So at 8 inches it would be roughly a 4 uvi with your fixture and 5.0 t5 bulb. If you want my absolute honest opinion I would personally not have a free range without having a solarmeter 6.5 to know exacts in the set up. I know they are expensive. But that is my 2 cents.Hey! Just curious if you think this is OK!
The closet vine to the light is 8in. I know that's kinda close but I'm still waiting on the new bulb. I can lower it when it comes in. The main vine shes been sitting on is 13in then the ladder is 25in. I feel like this gives good levels, yeah?
I have another strip of vines and ivyto hang all around it too
