I have a friend who runs bulbs with contacts on both ends... some special kind of "festoon" HID bulb, HE SAYS it increases thc quantity and quality...
Yeah those are those gavita bulbs, double ended.. closer to full spectrum made by philips agri division.. off the top of my head.

Oh well.. not a big deal if you havent run the high kelvin MH bulbs.. just looking for people pushing potency or quality with these..

Chemdog. 35~ days into flower. 3rd day with high kelvin bulb. (1.04KW/Scrog) Previous bulb Hortilux 1KW HPS EN.
Blue tape is my reference point, just to make sure I take the same picture a week from now.

Observations: The high kelvin bulb makes it easy to identify problems, slight overfeeding, on some leaf tips, nitrogen was reduced, ph was bumped up and new growth is a lighter green. Leaves to the center, showing good development of trichromes. Few red pistils. No insect activity observed.

Well I wish I had a day 60 shot.. somebody cut the piece I was documenting. Anyways, rock hard nuggets, and I had some people compare against some blue dream that was tested at around 20% THC. They said chemdog and the C99 (their favorite). Was easily as good .

The only bad thing I noticed is ripening of trichromes takes longer. Reds and cloudy took longer to develop.

Hello, all..

Anybody been experimenting with 10,000 Kelvin? in the 1KW range?

I was thinking of doing a mixed spectrum, HPS/MH but I pulled out the bulb and swaped for the high kelvin bulb. I got about 2 weeks to go to finish,.

Yield isn't a huge concern, just wanted to see if this will push potency up or tighten up things.
Ive ran a 10k as a finishing bulb for the last 2 weeks of bloom. Solistek ballast and bulb is one of the only true finishing bulbs on the market spec. designed for ripening and finishing during final 2 weeks of bloom.

It claims to increase resin and trich production 5-8% during final weeks. I honestly cant tell u that it made a difference. Ive only done 3 runs using this bulb in final weeks, I cant say I noticed a dramatic difference in quality but they def came out very frosty.
