DIY Free mini greenhouses

If you have walked by, looked over the fence, or driven past you have likely noticed the large plastic sheets over 2 of our 4 beds.  What you were seeing is thick clear mattress protector that we got free from a nearby mattress store stretched over the beds held up from the inside by tomato cages and on the bottom edge with scrap wood.

The 2 beds were covered over in late February and were completely thawed before the other 2 showed any signs of thawing.  They were planted with spinich, chard, garlic, lettuce and various other seeds by the first week of March and within 2 weeks of planting, here is what it looked like inside the tunnels:

Even though many days have not been too warm this season yet, our greenhouse regularly gets over 35 degrees C by 10am.  With proper ventilation early in the day, we prevent the plants from getting stressed.  There are TONS of seedlings of all types from beans to okra in there just waiting for another 2-3 weeks to be planted!
