So I have a modified greenhouse (solid walls 7 feet up and have been using the regular greenhouse film for the roof) I wasn’t getting the results I had been used to getting with either my indoor room nor my outdoor plants so I decided to break out the par meter. I was shocked to see that Inside my greenhouse I was only hitting about 600 on the par meter and outside the meter was banging between 2000-2100 so I knew something had to be done so I bought some crystal clear hard panels and started replacing the roof. The results are mind boggling. Now that I have the clear roof it’s literally so damn bright I need sunglasses and I’m hitting in the 1800 range on the par meter. I’ll show photos of the difference below. First and second pic is when I just started the panels and you can see I’m standing under the plastic and you can see the obvious difference on the floor. The 3rd pic are my wet walls and the last pic is new roof all installed and getting ready to reset. You can see just how bright it really is now. I have plenty of ventilation as well as wet walls so I can control temps and humidity fairly well. I’m just wondering is it possible I’d get light burn from the sun in the greenhouse even though I’ve never seen light burn on any outdoor plant? Maybe I’m too high and over thinking now that I see just how bright it is because the golden rule as always been you can’t have too much light right?
