rollup

turns out the greenhuose is too hot and needs ventilation. i was planning on ventilating on the gable ends but i realized this was not going to be enough and somewhat difficult to build. so, i took an idea from the csa farm that i subscribe to and installed roll-up sides. these were pretty simple to put together. i bought 1-1/4" electrical conduit and connected the pieces together with 1" square pieces of wood pounded into the ends. these have to fit very tight since only the corners of the wood are in friction against the metal. i might have made the wood pieces slightly larger. one of them slips a bit. i imagine when they get wet the wood will expand and tighten up nicely. after assembling the pipe, i taped the end of the poly to the pipe (with randy's help and javier's tape). once the entire length was taped i simply turned the end of the pipe which takes up plastic and in turn the plastic lifts the pipe. rolled up to near the eave of the greenhouse this provides ample ventilation. it takes just a few seconds to roll it up or down so now i have good control. in the winter i suspect i'll screw down the plastic the way i had it before to prevent wind damage.
