Hi mate, This is something I have been planning on using for my own grows. Just never had the cash to buy the fitting. The solar cure and migro light UV-b light fixtures will be perfect for a 1mx1m. Its a 2ft light, sitting at the top of your tent. About 2ft from canopy. Using the light for a max 2hrs in the middle of the light schedule, in the last three weeks of flowering...only!. You are trying to simulate high noon sun. You are right with your suspicions, UVB is dangerous so you should never open your tent while the light is on. It will damage your plants if too much is used. Check out Bruce Bugbee of Apogee Instruments on you tube. He is a professor from Utah state University that has done a lot of research on this matter...Lots of videos about light on his page. I hope this helps, good luck and happy growing. Feel free to Dm me if you need any other help
