I currently use reptile bulbs which barely get into UVB (on all the time) but think I am switching to the agromax bulbs. Ill be watching your thread but if you're asking, would begin my dosage (unless determinate data was provided) measured in μmol/m2/s of UVB correlating to any measurements available of the suns relative intensity (and corresponding UVB intensity) at the location to the species I'm growing. Like in the distribution you posted, there were different UVB readings at different parts of the year, I'd use the max level during summer or June and start there. Is MJ native to the UK?Thanks again!
I specified relevant sample info...one sample does not a t-, f-, or other distribution make...
Yes lots of caveats: location, angle of sun, cloud cover, reflectivity of surroundings...

But bottom line is that mimicking the sun is a logic pathway frought with deadends when growing indoors...
if uvb were so easy to deal with people like @Randomblame would have already nailed it...
What schedule, duration, intensity, equipment do you propose when using uvb for growing in a tent?

I didn't mean to come off as a know it all and am enjoying your grow/test!
With respect I disagree about mimicking the sun, but I have no clue! IMO, the plant that we know has been naturally selected to produce the best under the suns conditions and its native environment. We add WV to LED because we found plants have evolved to like certain WV, due to what the sun produces.
I do see your point though, that you're not looking to reproduce the sun, rather measure and test to figure what's best or optimal, not attempt to make an artificial sun. I'm completely on board and am excited to see what you find. Idk randomblame and am a new member so not familiar with all the history and testing and who did it but am enjoying the site so far. Ill be watching
I dont post pics although perhaps my paranoia will subside one day lol. I live in a medical state but was reluctant to even make an account (and now I'm addicted!) lolDiode limitations and wise use of resources require picking and choosing what is best benefit vs costs...
Random blame is a master grower and all around tecnical expert on rollitup, you can take what he says to the bank.
Got some grow pics? feel free to post here, i like a free wheeling growthread...my grasscity thread for this grow (which technically doesn’t start until 12:12) already has over 1500 posts.
that was the thought at the time. the uvb to build the resistance one week, then follow it up with the deep red to help the swell, it wasnt that hard using only one 2ft bulb in the middle hung high in the 4x4. now i have changed to using the uvb weekly, kind of alternating it in veg with the blue agro bulb 6400k.Logic? 660 promotes photosynthesis, which heals damage?
There is a lot of 660 from these 96s (huge blue too), 18 hrs everyday...

How would you work that? Uv every other week, 96s on regular schedule?
What happens when plants that were on uv, are shut off from it every other week? They maintain current level of resistance or have to start lower/over again? They keep putting on new leaves; one week later the top leaf sets haven’t had uvb, then you hit them with uvb?
Good work, that's a lot of time and effort, respect. Plants look good, they looked good before, but much better now.Day 31 from 12:12: Moms get 5th major defol.
