Man I have been trying to find a way to get the agromax pure UV up here to Canada. So cheap and such a good bulb by specs. I still think yes UVA is helpful to photosynthesis but UVB is where the trich production and THC increase comes from in terms of UV. And led is just not there yet with UVB.
And I'm growing with v1 288 3000k boards
i still love them but feel like I could be doing significantly better. First decision here will be fluence or
gavita... So sorry for the brain picking and thread clutter
@sshz but your grow is important to me.
I can sit quietly if ya like
