Coverage across the country

Commercial greenhouses, state by state

A greenhouse in Maine and one in Arizona solve different problems. Pick your state to see the frost-free window, the crops that pay there, and the structure built for that climate.

Northeast

Short seasons and hard winters. The strongest case for season extension in the country.

Connecticut 175 frost-free days Delaware 195 frost-free days Maine 145 frost-free days Maryland 195 frost-free days Massachusetts 170 frost-free days New Hampshire 145 frost-free days New Jersey 200 frost-free days New York 160 frost-free days Pennsylvania 170 frost-free days Rhode Island 175 frost-free days Vermont 140 frost-free days West Virginia 165 frost-free days

Midwest

Continental swings between summer heat and deep winter cold, with a compressed field window.

Illinois 180 frost-free days Indiana 175 frost-free days Iowa 165 frost-free days Michigan 155 frost-free days Minnesota 155 frost-free days Missouri 195 frost-free days Ohio 175 frost-free days Wisconsin 150 frost-free days

South & Southeast

Long seasons and mild winters, but humidity, fungal pressure and summer heat set the limits.

Alabama 230 frost-free days Arkansas 220 frost-free days Florida 330 frost-free days Georgia 240 frost-free days Kentucky 195 frost-free days Louisiana 280 frost-free days Mississippi 250 frost-free days North Carolina 210 frost-free days Oklahoma 200 frost-free days South Carolina 245 frost-free days Tennessee 210 frost-free days Texas 250 frost-free days Virginia 195 frost-free days

Great Plains

Wind loads and wide temperature swings decide what the structure has to withstand.

Kansas 190 frost-free days Montana 110 frost-free days Nebraska 170 frost-free days North Dakota 120 frost-free days South Dakota 135 frost-free days Wyoming 120 frost-free days

Southwest & Mountain

Water is the scarce input, and altitude brings intense UV plus the risk of hail.

Arizona 300 frost-free days Colorado 155 frost-free days Idaho 135 frost-free days Nevada 215 frost-free days New Mexico 190 frost-free days Utah 165 frost-free days

Pacific & Alaska

Maritime and extreme climates where protected growing turns specialty crops into a business.

Alaska 105 frost-free days California 280 frost-free days Hawaii 365 frost-free days Oregon 195 frost-free days Washington 200 frost-free days
