There are some in hydroton balls hydro and others in Biobizz light mixHow high from canopy are the bulbs? How far apart?
I noticed the size of flowers on tomato plants higher up that appeared since I got these lights on them are double the size before they open and you see the yellow flower as ones before lower and previous to using UVB. I have grown tomatoes outside many years and I have never seen that before.
My only concern is keeping light the over same area(top of your buds) but I suppose that is when the THC is supposed to help the plant fight it off but leaves may take a beating but if go slow I doubt it the one plant I mentioned just check look great but leave the plant exposed like that again but good to know there is leeway.
I should check the spread with meter once I am all hooked up as a cheap lux meter will pick up some of the visible light I tried already.
Grow looks great!
What temp/humidity level do you run in veg/flower?
Coco?
is that a 6 inch ocsilating fan ?
Looks like it. Not sure what kind that one is but vivosun has one on amazon for $30is that a 6 inch ocsilating fan ?
Fair enough but why not use a timer and not go near it?I'm not comfortable with discrete UV, few percent extra THC vs added chance of getting cancer, after all the shit I did my odds are high enough as it is.
@pulpoinspacei just unplug it if i have to go in.
i am midway thru my first run with UV. still figuring it out. right now i have two 36" 12% arcadia bulbs in a 4x4. running middle 6 hours of 12/12.@pulpoinspace
I am very inserted in your experience so far if any with UVB light before and after kinda thing?
I think that why many suggest to wait till half way through flower, but if it is just head stash then I don't care if it's super dank!i am midway thru my first run with UV. still figuring it out. right now i have two 36" 12% arcadia bulbs in a 4x4. running middle 6 hours of 12/12.
i am growing two strains that i just ran without UV, and so far, one of them seems to have an increase in trichome production and smaller buds.
the other strain looks similar to when i ran it without UV, with maybe more trichs (ill have to examine pics at the end)
day 49 right now so plenty of time to go. i'll post some pics and stuff when they're done.
i think thats what the extra strong agromax bulb is for just, headstash. running it through veg & flower shrinks yieldI think that why many suggest to wait till half way through flower, but if it is just head stash then I don't care if it's super dank!
Hit em on side of canopy if you can make room.
Would it not be better to force the plant to produce THC-terpines to combat the UV light that give it what could be called as plant suntan lotion ? Have you tested it with UV? Are you suggesting using it or stay away?not paying attention but knowing it works i decided to google benzyl salicylate... and come to find out its a uvb absorb er...View attachment 4334822
Same reason I don't use microwave ovens or cell phones.personally risks don't justify it
