Yeah, intend to have it covered properly. Was outdoors but stuff weather/people interveined, atm I have just a 240v 25W house lamp and you can see the light gaping through. That pc grow looks like something to try at some point but at this point in time I think just a mess would be made of it.
I have 2x 18 day old PJEMs 5-6 inches, each in 400-500ml(about 16oz) pots so kinda stuck with this set up now. Where they are has 4 sides white, hopefully that aids some. Have a big clothes cupboard could use but its beautiful wood. Is the lightness damage done just to the eyes and plant or are you implying like wall paint pealing bad?
