I have installed it before. It's great stuff and will last a long time. Woven Doesn't get stretched out like regular poly. I have noticed it blocks allot of light. Really keeps temps down though. I don't think it does anything at all for botritus at all. I guess it depends where you are at and what months you want to run. If you are only running in the summer in norcal it will kill it. If you want better spring and fall light, use something more clear and up your passive ventilation.
