New UV Supplemental Light Bars

Ciao Chucky guarda io le ho messe 2 barre marshidro e devo dire che un minimo di differenza nella potenza dei cannabinoidi l'ho sentita...quindi come dice qualcuno. sperimenta più volte con le stesse piante e vedrai sé senti qualche differenza. Ma un minimo sicuro lo fa... Buona fortuna

They overpromise as far as yield and probably most of the other things listed, and that's giving the benefit of the doubt to possibly increasing trichomes, which would correlate with higher potency, but don't expect that you can polish a turd. genetics are still going to be the greatest piece of that puzzle. If this has an effect it's small. Probably not worth the cost. Plus, you really don't want to be exposing yourself needlessly to UV, and you will forget to turn them off before entering the tent, lol. Definitely have an off switch accessible before you have to open the tent, lol. The idea behind UV is that it causes damage to the plant, and the plant reacts with 'extra' trichomes among whatever other adaptations take place to mitigate the damage being done. It's hoping the stress reaction is greater than the damage done and whatever ramifications come from it. Not unlike how a split branch will heal even stronger than it was before, if mended - or, a snapped branch forming a huge knuckle etc. "Field" tests never showed a statistically significant effect, but bugbee mentions indoor research crops potentially show an effect - this sort of stuff always requires redundancy and proven repeatability, as 80% or more of initial research is later proven false. "Initial studies" means take it as a grain of salt. This being a fairly simple context, it must be a small effect of they'd be more confident about it. So, still not a 'fact' it increases potency, but is possible. So, definitely should not be used in vege which will reduce the hours used per grow. From what i've seen these types of lights last 10,000 hours? That spec doesn't mean much without the %-dimming attached to it. In the end it's a hobby. If you want to experiement with it, have fun. Keep expectations low. Be safe with it... don't give yourself cancer or destroy your eyes.

From my understanding they degrade faster then any other LED as UV is destructive, They can help with WPM if you have that issue and you should not use them when the tent is open, It will also degrade anything in the tent faster like the tent walls and any plastic adaptors if they don't have any UV protectants in them. Other wise they where only good if you exposed them end of flower vs all the time if I remember correctly.. That extra bit of w/e it does vs its cost is the main draw back. I still think a good clone is better then UV. I'm forward this Q onto the peeps who thought me about UV and they can shed some light on it. Good Luck!
