I don't see any blue spectrum lighting, all they have is Mars stuff and the blues aren't there. Thanks though, I've never bought off Ebay, I never even think of looking there.

They have them...I only see in combination with the red now though.

2 minutes too late, a much better price too. I looked but all I saw was the reg Mars stuff without any blues so I bit on the Tarantula booster bars at 5x the cost....heavy sigh

Yeah multiple experiments.

UVA tended to bring out colors like the purples and tended to color petioles and such. Had pics of a tiger stripe petiole where it was obvious that the shaded parts were green and the parts that got uva were purple. Anthocyanin response.

UVB was tougher on the plants. Reduced harvest weight. Could not prove or disprove more frost because of mistakes made in the setup. I put pins in the buds and took pics from the same spot over flower but the buds swallowed the pins so I lost my reference point. My gut told me there was no significant impact I just could not prove it.

UVB seemed to make the plant finish faster but was damaging.

There was a correlation with higher CBG production but not enough data to prove causation

Under uvb I got measurable THCv on white widow that never expressed it without.

All that said I decided it would take 10+ experiments to find the sweet spot of power position and timing for uvb and didn’t think it was worth it. Went to the next shiny object.

UVA seemed like it didn’t really help or hurt but again more testing would be needed to say for sure. I was only using (2) 30 watt bars in a 4x4 space lots of room to increase power there and see what happens.

Did not fuck with uvc and don’t plan to.

What time did you have the UVA on? 10/50 or 15/45 (minutes) or constant? Wondering if I can turn my cycle time up and what signs to look for if too much

Well, this was years ago, going from memory.

UVA was like 8 hours during flower. UVB was only 2 hours or less. Middle of lights on.

When I couldn't time my uva and ir separate I just ran them for 2hrs on 1hr off. If the plants started pointing at the supplements I backed it off a little.
I noticed a need for more magnesium with the uva.

Ok, I think I will bump mine up tonight

I'm thoroughly enjoying reading all of the incredibly detailed info @MiGrampa is sharing with these experiments. Ditto for all of the what-ifs. knowledge, links and thoughts shared by everyone commenting. This is a great thread that really gets the gears in the old noggin' turning.
