Whether you’re a market grower or a home gardener, these useful frost blankets can help protect your crops from damaging frost. Unlike bedsheets, heavy-weight fabrics, and other covers- frost blankets are designed to protect plants without the risk of damage as they dry quickly and allow proper airflow.
Frost Blanket Weights
Bootstrap Farmer carries frost blankets in several weights. They are available in 0.9 oz, 1.5 oz, 2.5 oz, and 4.0 oz.
| Fabric Weight (oz.) | Transparency (%) | Est. Temp Above Outside (°F) |
| 0.9 | 70 | 4-6 |
| 1.5 | 85 | 6-8 |
| 2.5 | 30 | up to 8 |
| 4.0 | 20 | 8-10 |
*These temperature estimates are based on daytime temperatures above freezing. Individual results will vary based on growing zone and location.
We recommend the 4.0 oz frost blanket for extra protection before a frost. It can be used with a 2.5 oz blanket for layered protection. The additional weight of this blanket provides approximately 4-8+ more protection than the 2.5 oz blanket.
The frost blanket can last up to three years when properly taken care of and stored. Make sure the blanket is dry, and store it away from direct sunlight.

My only complaint is that I was not prepared for how well and fast all of the seeds would grow soI had to pot up earlier than expected! I am very happy with all of the seeds I have purchased from here!
I think I got near perfect germination on these. Cauliflower has always been challenging for me to time it out and know when to harvest. I've been learning that crops that have purple or reds in them (looking at my red lettuce varieties and purple sprouting broccoli) seem to bolt less quickly than their green counterparts in heat.
I have been buying seeds from you for the last 3 years. They germinate very well, and have produced the best gardens I have ever had. I just got my order for this year started in my greenhouse. For the first time I opened a packet of All Seasons Cabbage and there were no seeds in it. the rest of the order is doing great. The price of the seeds also good.

This is my first year growing straw flower. The germination rate is fantastic and you get so many seeds. Can't wait till they can moved outdoors and bloom in my purple flower bed.
Everything but the royal paste sprouted. Sometimes that happens. Will place another order for fall planting.
