UV radiation comes primarily from the sun. It comprises UVA, UVB, and UVC rays, each with unique properties. While some types of UV radiation provide health benefits, they can also pose risks.
The sun ... For the UV part of the light to promote resin production, it should be UVB light at roughly 310nm. I believe that SpiderFarmer UV/IR supplemental light is providing UVA at 380nm and above. Is the light capable of running UV and IR at separate timing?
uvb and uva meaning, I have 2 sets of Grower's Choice UV/IR addon bars on my two ROI-E720's. The sun emits UV light, which is then categorized into three types: UVA, UVB, and UVC. While UVC is mostly absorbed by the Earth's atmosphere, UVA and UVB can reach the surface and play a crucial role in various biological processes, including cannabis growth. I been using UVA and UVB lights for them and moved them up from a 14/10 to a 17/7 Light schedule. A mix of Purple Runts, Gods Gift, Scarface OG, whatever came from the shop I was smoking on.
uvb and uva meaning, UV light is typically divided into three categories: UVA, UVB, and UVC. Among these, UVC is harmful to plants and is not recommended for cannabis cultivation. The Effects of Blacklights on Cannabis Growth Blacklights primarily emit UVA light, which is a part of the ultraviolet spectrum that has minimal effects on plant growth. Starting Out ($50-200) A reptile UVB bulb in a basic fixture runs $30-50 total and gives you a way to test the concept without major investment. Far-red LED strips for DIY setups cost $40-80 for a 4x4 area. Reality check though - you'll see some improvement, but don't expect dramatic transformations with budget gear.
Serious Implementation ... I want to use UVB lighting because I've heard some good things about it. Does anyone know what type or model I should try. Also the wattage, how far above the canopy should the lights be.
