Did it say which kind of UV light? UVA, UVB, or UVC?I've also been seeing people starting to use UV light to kill/ward off spider mites so i did some checking. From a reliable source:
"UV treatments had a negligible effect on survival of adult female spider mites, but killed more than 99% of larvae and nymphs, and 100% of eggs, both in a laboratory strain and a wild-type strain collected shortly before the experiments were conducted."
So you should be able to get a handle on them by just killing the eggs and babies. Males generally live about 7 days, females about 11 days.
Hey Sshz are you going to upgrade to those Spider Farmer 7000's anytime soon. They are getting 3.57 pounds per light if my calculations are correct.
Pretty cheap to.im amazed how much can b grown over an 5x5 6x6 footprint..they are 800 to 1800 cheaper than the lumatek zeus and gavita here..huge savings.do they throw out pink colored light...Hey Sshz are you going to upgrade to those Spider Farmer 7000's anytime soon.

Ah, then yes. That explains it.Gavitas not avail here...whats happening is they are coming up on evilbay for these ridiculous prices.ive tried to get a sunsystem light from growers choice posted to here and was close to 900 bucks. lol.
Great read. Interesting addition to ipmI've seen both UV-B and UV-C mentioned as the UV to use......... but not UV-A. @Aqua Man posted a report in July in another thread.
Physical Control of Spider Mites Using Ultraviolet-B With Light Reflection Sheets in Greenhouse Strawberries - PubMed
Development of spider mite management technology other than chemical control is desired because of the serious development of acaricide resistance worldwide. Recent studies have evidenced the lethal effects of ultraviolet-B (UVB) radiation on spider mites. To develop the technology on how to use...pubmed.ncbi.nlm.nih.gov
I'm assuming both are somewhat effective at this point...............
How are you liking the Gavita? Have you used any less expensive LED options to compare to?Sshz:
Curious if you ended up keeping the Gavita controllers and adapters in play, or are you just running full power and adjusting light height on this run?
im on a 2nd run of gelato mint, but this is the first time I’m using the 1700e lights (with controller) and there’s a bit of a learning curve here with the new lights. I’m playing around with the Korona light app to help set power levels/ppfd. But haven’t compared it to a fancy meter for any accuracy. Not much posted by folks running these lights yet so I really appreciate you sharing your experiences and knowledge. Your last thread helped me immensely.
I’d been running two 4x8 tents pretty continuous, each with 6 600w galaxyhydro blurple lights for a few years. I ditched the tents and just converted the entire room about a month ago. His far, I like the gavitas a lot more and being out of the confines of a tent makes it a lot easier to work.How are you liking the Gavita? Have you used any less expensive LED options to compare to?
