Quick Answer: Bootstrap Farmer’s greenhouse lineup splits into three real tiers by budget and permanence. The Hobby Greenhouse Kit (10’ x 12’, about $584.99-$649.99) is the best entry point for a backyard grower. The DIY Gothic Greenhouse Kit (starting around $935.99 for 14’ x 20’) is the best budget hoop house, using steel hoops under a 6-mil poly film instead of metal panels. The Gothic All-Metal Hoop House Kit (roughly $3,832.99-$20,399.99) is the best permanent structure — NRCS-compliant galvanized steel and aluminum, built for decades rather than one re-cover cycle.
If the name Bootstrap Farmer sounds familiar, it’s because this site already recommends it repeatedly — just not for greenhouses. Its Extra Strength 1020 trays are the base pick in our best seed starting trays roundup, its germination mat is the premium pick in best seedling heat mat, and its trays and cells get cited in greenhouse propagation for the same 2-year-warranty build quality. What’s never been covered on this site is the fact that Bootstrap Farmer also sells the structures those trays go inside of — from a $585 backyard starter kit up to NRCS-compliant commercial high tunnels past $20,000.

Bootstrap Farmer greenhouses by the numbers:
- $584.99 to $20,399.99 — the real price spread across Bootstrap Farmer’s own three greenhouse tiers, a far wider range than any single brand this site has reviewed. The cheapest and most expensive structures in the lineup differ by roughly 35x.
- 7 lateral wind-bracing points — how the Gothic All-Metal Hoop House Kit is reinforced along its full length, per Bootstrap Farmer’s own product specs, on top of the gothic arch profile that’s designed to shed snow rather than let it pool on a flatter roofline.
- NRCS-compliant — the Gothic All-Metal line is built to the US Department of Agriculture’s Natural Resources Conservation Service structural standard, the same program that can help fund high-tunnel construction for qualifying growers — a specific, checkable claim rather than a generic “heavy-duty” label.
- 6-mil, 4-year-rated poly film — the covering on the budget DIY Gothic kit, over 16-gauge steel hoops measuring 1.315 inches outer diameter. Expect to budget for a re-cover around year four, unlike the all-metal tier’s permanent panels.
Bootstrap Farmer greenhouse tiers at a glance
| Kit | Best for | Structure | Typical price |
|---|---|---|---|
| Hobby Greenhouse Kit (10' x 12') | Best entry point | Metal frame, scissor door, poly cover | ~$584.99-$649.99 |
| DIY Gothic Greenhouse Kit | Best budget hoop house | 16-gauge steel hoops, 6-mil poly film | ~$935.99-$2,199.99 |
| Gothic All-Metal Hoop House Kit | Best permanent structure | Galvanized steel + aluminum, NRCS-compliant | ~$3,832.99-$20,399.99 |
1. Bootstrap Farmer Hobby Greenhouse Kit — Best Entry Point
Bootstrap Farmer Hobby Greenhouse Kit (10' x 12')
- 120 sq ft footprint with an inside height of roughly 7 feet 11 inches at the peak.
- Scissor-style metal door included (not sold separately from this kit).
- Optional roll-up side kit available as an add-on for passive summer ventilation.
- Metal frame construction sized for a backyard grower rather than a production setup.
This is the size that makes sense if you want a real walk-in structure without committing to a full hoop house. At 120 square feet it’s comparable in footprint to this site’s small greenhouse picks, but the scissor door and optional roll-up sides are details usually reserved for larger commercial kits. Skip the roll-up side add-on if you’re in a cold climate and plan to keep the structure sealed most of the season — it earns its cost in a hot-summer climate where passive venting matters more.
2. Bootstrap Farmer DIY Gothic Greenhouse Kit — Best Budget Hoop House
Bootstrap Farmer DIY Gothic Greenhouse Kit
- 16-gauge steel hoops, 1.315 inches outer diameter, in a gothic-arch profile that sheds snow better than a rounded roofline.
- 6-mil, 4-year-rated greenhouse poly film covering.
- 14' wide stands roughly 12.5-13.5 feet tall at the peak; 20' wide stands roughly 15.5-16.5 feet tall.
- Lowest cost per square foot of the three tiers, at the trade-off of a poly cover you'll replace periodically instead of a permanent panel.
The gothic arch is the detail worth understanding before you buy: a rounded hoop-house roof can pool snow at the top where the curve flattens out, while the steeper gothic peak sheds it the way a pitched roof does. Pair that with a 4-year-rated poly film and the honest math is that you’re trading a lower upfront cost for a recurring re-cover cycle — budget for a new film every three to five years depending on your climate’s UV exposure and hail risk, the same consideration we cover in our best greenhouse plastic picks.
3. Bootstrap Farmer Gothic All-Metal Hoop House Kit — Best Permanent Structure
Bootstrap Farmer Gothic All-Metal Hoop House Kit
- US-made galvanized steel and aluminum framing and panels, replacing poly film entirely.
- NRCS-compliant construction — the USDA's Natural Resources Conservation Service structural standard.
- Wind bracing integrated at 7 lateral points along the full length of the structure.
- 14' x 20' runs about $4,487.99; 20' x 20' runs about $5,434.99; longer commercial lengths climb toward $20,399.99.
NRCS compliance is the detail that separates this tier from most hobby kits reviewed on this site: it’s the engineering standard the USDA’s Natural Resources Conservation Service uses to evaluate high-tunnel structures, including for growers applying for conservation-program cost-share funding. That’s a specific, checkable bar, not a marketing adjective — and it’s why this tier costs four to ten times more per comparable size than the DIY Gothic kit above. If you’re building something you expect to still be using in fifteen years, or you need the structure to qualify for a USDA program, this is the tier that’s actually engineered for it.
How to choose a Bootstrap Farmer greenhouse
- Start with the Hobby Kit unless you already know you need more. At 120 sq ft and under $650, it’s the lowest-commitment way to find out whether you’ll use a full walk-in structure before spending four figures.
- Budget for a re-cover cycle on the DIY Gothic kit. The 6-mil poly film is rated 4 years — treat that as a recurring cost, not a one-time purchase, the same way you would for any poly-covered structure in our polycarbonate vs. glass comparison.
- Only step up to the all-metal tier if permanence matters. The jump from the DIY Gothic to the All-Metal kit is roughly 4-10x in price for the same footprint — worth it if you want a structure that outlasts multiple poly re-covers, not worth it if you’re still testing whether greenhouse growing is for you.
- Check NRCS program eligibility before you buy if cost-share funding matters. Conservation-program funding rules and regional availability vary; confirm with your local USDA NRCS office before assuming a kit purchase will qualify.
- Plan the foundation separately either way. None of the three tiers include a foundation — see our greenhouse foundation guide before you order.
The bottom line
Bootstrap Farmer earns its reputation on this site from trays and heat mats, but its greenhouse kits cover a genuinely wide range: the Hobby Greenhouse Kit for a first backyard structure, the DIY Gothic Greenhouse Kit for the cheapest real hoop house per square foot, and the Gothic All-Metal Hoop House Kit for an NRCS-compliant structure built to last decades. Match the tier to how long you plan to keep growing in it, not just to the sticker price — a poly-covered kit and an all-metal kit solve the same basic problem at completely different time horizons.
