I don't usually click on that link. Maybe a mod will see this and check it out. No E, I haven't really experimented with much of anything, I am just getting to the point were I am comfortable with the operation as it stands, just need to get a 'good' exhaust fan, I am sure the cheap one I bought two years ago has outlived its useful life and the link that SouthFloridian provided in his thread, These fans are the real deal, is going to get a couple of bucks from VV. They have an exhaust fan, 8" ducting 400+ cfm, that is temperature rated for operation to 145 degrees for less than $200.00.
Postie is intending to use a uvb for his grow, he is still a fw months away from startng. VV
