A question about automatic vent openers.
I am working on plans for a hot house/cold frame to start my seeds in this spring. My question is the following: Can I rig up just the powertube to open and close the sash I will be using, or will this not work, and do I need to go with the extra expense and buy the entire vent opening unit? http://www.littlegreenhouse.com/accessory/vent2.shtml
