oh you're cool. yah uv cover works well. the key mid summer is.....wood chipped pathways....that you water down in the mid day. also, uv shade cloth over the top of the dome. this brings the temp down about 15 degrees inside. also, there's a large intake fan bringing fresh air in that blows out through the door entryway. sort of a swamp cooler effect...blowing over all that wet mulch and transpiring plants. ;) the pond too....as it evaps throughout the day. just top that pond off each day...and moisten the pathways. :) i grow heat loving veggies...like maters...through the end of summer. they fuckin' love it. they grow right on out the top of the dome. :)
