Oh Jojoe, your growlight question...first of all I'm the wrong person to ask about kelvin!!
Since the plants are in my living space I thought it'd be nicer to not have long florescent bulbs and structures so I bought a lot of clamp lamps (16 of them) and I use florescent microbulbs with 5000 lumins of light each, so its pretty bright. I have those on for about 14 hours each day in the winter. People on ATP (in your other thread) were saying that one could do it cheaper, and with less mess by using shop shelves and florescent lights T whatevers for whatever fits your needs, If its for plants for pleasure I would say start with the cheaper ones, or mix cheaper with something midrange! These plants can go through a lot during the winter and bounce back when they're back in the sun! And where you live sounds warm and sunny and they love that! Here in Seattle we very often have low 60 degree weather at 4th of July, so the succulents need more during the winter since it is so out of their norm! Its funny though I just looked and you and I are both zone8 you in A and me in B, I think though that you have humid and hot summer weather, and we really don't have that! Anyway, its all exciting, I love plants and enjoy seeing what other's plants look like, what they enjoy and what they find challenging!
