In curious what uva/uvb bulbs Canadians are using and at what distance’s.
I looked into one brand everyone recommended on here and i could only find it on Amazon.ca for $90 for a 4ft bulb, I never pulled the trigger

I used the hlg uva bars last round. Definitely improved on potency and taste compared to Previous runs. I turned mine on last few weeks of flower for 12 hours. But I did intervals of 2 days on, 1 off.
Someone over in The bean basement posted a video with some professor referring to study’s showing how uva intervals was more beneficial. I may try 1 on 1 off this next round. See if I notice any difference.

I'm interested to see the results. I have read some good things about uv supplements. Not only is there a spike in potency. The increased resistance to disease is a huge bonus.

Cutter makes these, I have 4 of them just haven't got around to hooking everything up
i know nothing about DIY led's.
what kind of coverage would say those 4 get you? what kind of distance would you mount them and how long would you feel safe running them daily in flower or every second day?
 
I run my HLGs in 3*15 minute cycles in veg and flower and for the last two weeks i run them on 3 hrs, off 1, 3 times. First run with them but I can already tell plants are shorter and more branchy/less internode spacing.
