UVb an experiment

[Rusty Trichome]

Nice setup Rusty

Thanks. Necessity is the mother of invention. :thumbsup: Plus, I'm a woodworker and have the tools and stuff.

I may try to do a run substituting UVb bulbs with some actinic whites. I realized in the one grow I use a super actinic white (435nm peak) for clones and seedlings 'cause it really helps with root production, and if we veg under the combo of 6500K fluros and that actinic the young plantlets stay short and compact.

I have a dual-bulb Sunpaq ballast from coral reefing. Plant's don't do well with just the "dual actinic" bulbs at all, and the times I've tried, quickly switched back to either the dual daylight bulbs, or CFL's. (dual actinics: square 4-pin 32w bulbs, 420nm and 460nm)

Plus another experiment I want to try is using some UVb during the vegative growth to see if there is an improvement. Only problem with that here in my personal grow, since I grow SOG, they are only vegged for 2-3 weeks, the time it takes to transplant the clone plugs and establish them into the delta blocks.

I've been giving around 4-6 weeks veg. Any longer veg than that, and in flower the plants will stretch way beyond my 3' effective light range and is pretty much a waste.

I'm all set-up for UV in veg, once the clones root. I do have a couple of mom's in there right now, but way too early to expect a difference.

Weezard: Sorry. The picture of the outdoor plants threw me. :thumbsup: A nice nugget in the pocket is always a "10". :jointsmile:
