Bookmark or Share- How do I properly use supplemental UV/IR light? - THCFarmerAs others have said, wavelength with uvb is key. I never heard about using IR, but I use mine with a timer for the middle of the light cycle. T5 or t8 bulbs are the only way to go for uvb. Led's are not there yet in efficiency or cost, but they sell uvb bulbs that offer uvb and uva, which should work together much better.
- Should I add UVB Light? - THCFarmerThese UVB bulbs will definitely effect the amount and consistency of trichomes. (notice I did not say THC) They will make you turn cloudy and then amber pre-maturely I think the overall effect on the plant is detrimental. TLC testing the resulting harvest DOES NOT show higher total cannabinoids in my grows.
- Do You Run UV Lights at Late Flowering? - THCFarmerUVB is the light that triggers an increase in terpene/oil production. It also has some antimicrobial properties against pm/mold and some insects. Unfortunately, most manufacturers are not offering lights with UVB. Only a few companies are selling UVB fixtures for cannabis.
- Use of UVA and UVB light! - THCFarmerUVB is quite a range of spectrum and there are currently no LEDs that produce it well or for long - they burn out quick. UVB can damage plants or can improve cannabinoid profile depending on use. The addition of trichomes via UVB is a common statement made by people that use it, I found no evidence to support this.
- using uvb lights during flowering - THCFarmerI know using uvb in the early stages makes the plant produce more resins .. to protect itself from the uv radiation .. i know of a grower that uses it for 4-6 hrs a day with his 1000w .. but only for the first 4 weeks of flower .. after that it does something to the trichoms ( his observations ) thats about all the help i can give ya .. happy growin
