Floating Row Cover or (Remay)

[amideutch]

You hear people often talk about floating row cover or Remay for protecting their planted out seedlings when freezing temperatures are forecasted. What I didn't know is they have different fabric weights starting at .06oz per square yard with protection down to 27 deg to 1.5oz with protection down to 20 deg F. Heres a link. Ami

I think they are exaggerating a little. I have the medium/heavy weight 10'x200' blanket. I think it's the 1.2 oz., but I bought it 9 years ago so I can't be sure. It might be the 1.0. It gives perfect protection down to 29-30, and if I double it up, down to maybe 25-26.

I wouldn't trust any thickness without supplemental heat at 20 degrees!

I generally use the weight that claims 4 degrees frost protection. It is supposed to let in 85% of the light. I use them more for protection from wind, hail, and bugs. We did have a frost night before last, although the temp was only 38 degrees F. All survived with no problems. Today we are getting wind gusts of 40 + mph. I really like them. I leave them on as long as possible.

Yeah, I tend to use mine (usually in 61 inch widths) for protection from bugs, critters, and especially wind rather than for frost protection. I cut some lengths of 9 gauge aluminum wire and bend them into half-circles and poke them into the ground and use those to support the floating row cover. I know you're supposed to be able to let it lie on top of the plants, but these are small brassicas and the wind does whip the fabric around alot, so I like having some support. I use a combination of bricks, metal fencing posts, and 1 liter soda pop bottles filled with water as weights around the edges.
