Grow room eye damage
Feeding done, excess runoff removed from trays and all is right with the world. Time to sit back and take in the beauty of the green canopy you have created. Temps look good, leaves are healthy, now all that is required is patience and vigilance. Unlike the California hippies from the 60s we have an unbelievable amount of knowledge at our fingertips.
Youtube video tutorials and chat forums all guide us as we pursue the perfect bud. Trial and error growing has been replaced by clear advice and insight handed down through the generations and finally placed on the internet.
So what could possibly go wrong, right?
Indoor growing requires strong lights. These metal halide and high pressure sodium lights have done wonders for yield and quality, but they are doing slow, permanent damage to our eyes. I have always felt a strain on my eyes when in a grow room but I guess you are distracted by much more important things. After meeting with the Method Seven guys at the recent cannabis fair in Prague I became aware of the problem and also the solution.
There is quite a bit of science involved in all this so buckle up!
Daylight has UVA and UVB radiation in it from the sun. A good pair of sunglasses will filter out this radiation and protect your eyes, but there is a third form of radiation called UVC. The ozone layer very helpfully filters out this radiation outdoors so sun glasses manufacturers do not concern themselves with this filter. In the grow room however those magical MH and HPS bulbs crank out UVC radiation. Good for plants, bad for eyes. Now for the really frightening bit, prolonged exposure to these grow lights can lead to permanent loss of color perception, it can mess up your night vision and give you cataracts.
I got a pair of Method Seven glasses over the weekend. In a few months time I will do another post on how they are working for me, but initially I can feel they take the strain away and let you look at your plants with much better color perception. Marijuana has many health benefits, if you grow it you are helping others but you also need to protect yourself from the harsh working environment. Go on the internet and get as much information as you need and then get the protection. The glasses work and are just as important as all the other vital pieces of equipment in your grow room.
