Thats good about the glass , yes let those girls get all the lumens they can outta those lights. From the pic they only looked a couple of inches away from the lights now that im not high I can see there is still some space left , lol.

How are the buds on your girls forming? Its kinda hard to tell from your pics. I do see some white pistils shooting out in various places though. It amazes me how nice cannabis looks once it starts flowering.
