FAQ
What types of crops are suited to grow in the SF-23? The SF-23 commercial greenhouse excels at growing many different crops. From annuals to perennials to vegetables, the SF-23 can be configured in different sidewall heights and with different crop load strengths to satisfy almost all growing requirements. Ventilation, heating and cooling can all be configured to match your needs.
I live in Montana. Is the SF-23 going to hold up in my snowy winters? The SF-23 has been engineered to stand up to most snow loads in the lower 48 states. We have installations in Idaho, Nebraska, and Minnesota.
What are the advantages of a double poly roof and sides? Inflating two layers of poly film will give you a tighter layer that will flap less in the wind and therefore will last longer.
It will also give you a dead air space that will help to insulate the greenhouse. We recommend a double poly roof and sides for anyone in a colder climate.
Can I assemble the SF-23 by myself? Yes you can. It comes pre-drilled from the factory and is ready to bolt together on top of you concrete pad. We do suggest some experience in greenhouse setup and construction. If you are unsure or if you would rather have someone else do it, gives us a call and we can give you some recommendations.
Why would I need the optional horizontal end truss?
The horizontal end trusses strengthen the end walls for growing heavy crop loads such as tomatoes and other climbing plants and vegetables.
This allows you to place climbing strings anchored over the trusses to maximize growing space and yield.
I live in a fairly cold environment. Do I need any ventilation at all?
The horizontal end trusses strengthen the end walls for growing heavy crop loads such as tomatoes and other climbing plants and vegetables.
This allows you to place climbing strings anchored over the trusses to maximize growing space and yield.
