8 FOOT BT 12 FOOT---------- WATER, & ELECTRIC INCLUDED. I BUILT THIS IN BETWEEN RAIN, WIND, AND COLD DAYS. NOW FINISHED IT HAS GREAN BEANS, BROCCOLI, LOTS OF PEPPERS, TOMATO'S, CUCUMBERS, AND SWEAT PEAS. SO FAR IT SEEMS TO BE WORKING AND STAYS WARM DURING COLD DAYS. IT IS NOW JUNE 10TH AND WE HAVE NOT SEEN A DAY OVER 75 , SO I DON'T KNOW HOW IT WILL WORK IF WE GET HOT DAYS.
I HAVE AN ATTIC FAN INSTALLED AND SET TO TURN ON AT 90 DEGREES. SO FAR IT RUNS A LOT DURING THE DAY. TIME WILL TELL BUT I EXPECT TOMATOES BEFORE JULY 4TH.
