Hey just wondering what UVB bulbs are appropriate for increasing cannabinoids/terpenes during late flower?
1) I noticed there is 2.0 UVB, 5.0 UVB, 10.0 UVB AND 20.0 UVB on Amazon. Is this number important for selecting a bulb?
2) I run 2 400w HPS in flower. What wattage is appropriate to complement the bulbs I am using?
3) What distance from the canopy would you place a UVB bulb?
