4 hours a day x 2 days with two 4ft pure uvb agromax bulbs about 3 feet off the canopy. Moved the purple kush into the flower room on 2nd day of uvb supplemental lighting. That's when I noticed the blueberry acting stressed with curled leaves. I shut them off and noticed the damage to the purple kush the next day. Waxy dark green, curled leaves. The blueberry never fully recovered. The PK looks good 2 weeks later.

I was just one click away from placing my order to buy these. But thought, my last run turned out wonderful. Maybe I shouldn't get em. I dunno... there something I've always wanted, but I just haven't seen enough on them to be super beneficial to buy them.

If you do buy them and you've run reptile bulbs before, then consider the reptibulbs as a childrens EZ Bake Oven, and Agromax pure UV as a microwave. I'll still be using mine but very very carefully

I know how weak and basically useless the reptile bulbs are for adequate UVB exposure. I haven't ever tried even those. Im still debating if the $120 is worth it

I'm thinking hardening plants off to it is the big hurdle for most.

They make (2) different UV bulbs and the % of A/B are not the same between both. Guys keep buying the stronger bulb not meant to be on more than about 15 minutes or so and run them with the light schedule and it causes issues.

Sorry about the sunburn @vhawk, but there's the magical 15 minutes I am talking about guys.

Ya you wanna use the uvb bulbs for 15 mins of the middle 4 hours of your 12/12 cycle.

I've got them on a separate timer now. I would rather burn my hide once, then fry anymore plants. If I didn't buy into the UV hypotheses I wouldn't risk it. And though it goes against my example, I wouldn't recommend adding these lights until someone has several grows to completion. There is soo much other shit to dial in, adding the lights will complicate things if something goes wrong.

I definitely think that is is very strain dependent. Ive had a few UVB bulbs. the Agro max was the latest. Twice it really fired up indicas even with good spacing ~28". Other times it looked as if the plant was barely affected. I did exposure on several different intervals. Some of the indicas seemed to suffer with even 2hr daily exposure. Sativas fared far better. I also noticed that plants in much larger pots managed far better under intense irradiance in general.

I ended up switching out the agromax and dropping in the Hortilux Uvb. The plants love it. It's not as much UVB exposure but they respond to the spectrum and it gives some uvb. In a few weeks, closer to harvest I plan on getting the Agromax back in there.

I know that this is an old post but did you ever switch back to AgroMax pure UV?
I'm gonna try it out to combat any PM spores. Just curious about setting up a timer for my indoor grow.
Any information is greatly appreciated.
Cheers
