Almost all of the 2.0 going in looks like this. And I was wrong on my height estimate.
Closer to 2 ft going in. View Image
Ha! I've prolly never seen an untopped 2.0 before, all my clones get topped while in solos...
Actual OGKB phenos I leave alone but I should probably try your style grow someday with 20 plants or so under a light.
I'm super pleased too with the results from my DE CMH thousand and 630.
$50 Chinese DE 630 bulb with conventional high frequency ballast killed it just like the $575 Nanolux low frequency thousand.
I had my lights up nine feet and lit room at 30 watts per sq ft with great density and penetration but the smell and flavor are much improved and I took everything at sixty days too.
So glad I switched!
