GrowSpan Mini Cold Frames

Keep your small plants out of the cold or start new plants early with our GrowSpan Mini Cold Frame!

  • Provide shelter for your tender plants or harden-off seedlings.
  • These mini hoop buildings are ideal as over-wintering structures for young or delicate evergreens or any shrub that cannot accept direct exposure to winter conditions.
  • Framework is constructed from 19 gauge, 1.05" OD USA-made, triple-galvanized structural steel tubing.
  • Cover is made from our 6 mil, 4 year greenhouse film that has UV-blockers, an anti-dust additive, and comes with a 4 year warranty. Fabric clips included.
  • Rafter spacing: 2'.
  • Ground posts are included. We do recommend using our Composite Lumber and our Stackable Joint Corners, sold separately, as a base.
  • During the warmer summer months, replace the greenhouse film with our 60% Black Knitted Shade or our Insect Screening. Ask your sales associate for more details.
