A study assessed economic returns to three season extension methods for strawberry production in the Intermountain West; high tunnels only, high tunnels in conjunction with low tunnels and targeted in-ground supplemental heating. High tunnels provided net returns of $1,943.57 or $15,548.56 per hectare. Low tunnels added within the high tunnels resulted in a positive increase in net returns for one cultivar. Supplemental in-ground heating increased net returns by up to 50 percent for both cultivars.
