COLD FRAMES

 
Our cold frames are built with the finest western red cedar and 8 MM twinwall
polycarbonate.  Solar vents allow our cold frames to open and close automatically.  
Solar vents keep your seedlings warmer when the outside temperature drops and 
cooler when the outside temperature rises.   When you have a solar operated cold 
frame, you can go away for the week-end with out having to worry about your 
seedlings burning up on a sunny afternoon or freezing on a cold night.  Get a big 
jump on your spring gardens with a solar vented cold frame from 
Cedar Tree Greenhouses.

Installation Instructions

When first receiving your cold frame set it on its side and attach the solar 
vent by squeezing the two legs together and inserting them into the two holes 
in the bracket attached to the front of the cold frame.  Your cold frame is now 
ready to operate.  After the initial connecting of the solar vent the cold 
frame can be connected and disconnected from the solar vent by gently 
lifting the top of the unit and reaching in and disconnecting or connecting the 
vent.  Do not force the top open past 2 or 3 inches as you can damage the 
cylinder.  The solar vent will open and close the top of the unit as the
temperature fluctuates.  It is fully closed at 65 degrees and fully opened at 85 
degrees.  The solar vent is adjustable by about + or - 5 degrees.

                  
Cold frame in partially opened position and cold frame full open with solar vent 
detached. It is best to prop the lid when in the fully open position so as not to 
strain the hinges. 


Your cold frame is now ready to give you many years of service. 
Get an early start on your garden and have vegetables a full month 
before anyone else in your neighborhood.
