The underneaths has coal tar epoxy on them,I didn't want the tops black cause it would heat up to bad so I left the tops yellowI was going to paint it black but I was wondering if it's really needed considering I'll be laying reflective bubble wrap over it which is completely light proof?
I guess it would be smart to have some extra protection just because. I was surprised when I see grows without painting them. Wasn't heisen's cloner run with just the plain yellow lid? I was wondering why it wasn't a big deal.
hold that wrap up to a good light and see if light comes through,The wrap i got from lowes leaked lightThese reflective wraps I have are and I only know because I tested them. They used to be cooler containers for food shipping. I put one over my head and the only light that came through was at the seams.
I like the black epoxy on the inside a lot! I'll steal that one, thanks!

Leaf tip yellowing doesnt necessarily mean it is burn,It could also be a deficiency.Not always burn.i noticed my highest ppm requirement has always been during the stretch and when the colas are building and stacking bud sites.After the stretch and stacking is finished it seems like the ppm levels off at around 700.I mean think about it,look at how much plant mass they are creating during the veg and early flower stretch.I dont think plants need as high an EC as what people claim during the flowering process.Most of my friends that also grow in dwc say the same.EC drops off after the stretch and your basically just maintaining a number at that point.My plants reacted quite strange, to my limited understanding, through the flowering cycle.
I ran a pretty high EC with 2/2/1 ratio, dry nutes, but the ec dropped steadily every day during veg. During flower I dropped the ratio to 2/1/1, to lower Nitrogen, but no matter how much I lowered the ec it continually raised the ec and drastically. You could see the burning in the tips of all the leaves.
Why is it that when the plant should have been requiring higher EC during flowering it actually ended up needing not even half the ec as in veg? The Masterblend is 4-13-38 with cal/nit and Epsom for the grow.
