Switch for last 2 wks. back to MH from HPS ??

[sky_blue]

I've read and heard that going back to MH for last 2 wks. of flwr. increases THC production because of the extra Uv-B. Supposedly, the HPS doesn't provide UV-B, but the 600HPS is definitely more efficient and produces more light/ higher PAR.

Anybody want to chime in? Does switching to MH work? Is it worth the potential shock to the plants??

Thanks everybody :)...

Thanks, Pauly. Have you personally noticed a potency increase due to the MH switch?

Your welcome :) I can visually see a difference. For potency i believe so imo. Just kinda hard to tell. Need to get them tested for real true results

this may seem like a stupid question but can i just switch out the bulbs in the same hood?

No such thing as a stupid question. The answer is, no you cannot, unless...
You have a) switchable ballast or
b) a conversion bulb.

I will be doing this the last 2 weeks with my OJ's Haze. Supposedly brings out an LSD quality to this strain. We'll see.
