ANSWERS — THE HONEST PROBLEMS
What actually stretches a greenhouse install — and how to compress it?
The greenhouse is the fast part: 7 days to the truck, 10 to 14 on the pad. The schedule you should worry about is everything around it — permits, site work, concrete, and power. Here is the honest list, worst offenders first, and where you can buy time back.
AMERICAN ROOTS — ANSWERED BY THE PEOPLE WHO BUILD IT · UPDATED JULY 2026
01 — THE SHORT POLES: US
Our part of the schedule rarely moves.
The frame ships 7days after order — every member cut to your county's wind and snow load — and stands in 10–14 days with a 4-person crew, an impact drill, and no crane. There is no welding or cutting on site. This is the predictable part; the surprises live in everything happening in parallel around the building. See the full deposit-to-growing summary.
02 — THE LONG POLE: PERMITS
Approval time is your jurisdiction's clock, not ours.
Permitting is usually the single longest pole, and the fastest way through it is a PE-stamped set — the desk is comparing your numbers to the code, not grading effort. Start it early, because it runs on the county's calendar. See greenhouse permits.
03 — SITE WORK AND THE PAD
Concrete has its own opinion.
Grading, drainage, and the foundation set a big share of the calendar, and cure time is real — no crew rushes concrete. Plan the pad in parallel with the order, not after it. See foundation requirements.
04 — POWER AND UTILITIES
For a lit or climate-controlled build, the service can be the true critical path.
Grow lights and climate equipment are a large connected load, and getting adequate electrical service and the utility hookup scheduled can outlast every other step. Get the utility into the conversation early — it is the delay growers discover last and regret most.
05 — WEATHER WINDOWS
A ground freeze is a real, regional constraint.
Pouring pads and raising steel before the ground freezes is a genuine seasonal limit. Steel ordered before the freeze is a greenhouse growing by spring; ordered after, you wait for thaw like everyone else. In cold climates, the calendar, not the crew, is the boss.
| STEP | WHOSE CLOCK | HOW TO BUY TIME BACK |
|---|---|---|
| Frame lead time (7 days) | Ours — fixed | Order early; it runs in parallel with permits |
| Assembly (10–14 days) | Ours — fixed | Have your crew or installer staged and ready |
| Permitting | Your county | Hand them a PE-stamped set on day one |
| Site work & pad cure | Local + physics | Grade and pour while the frame is in production |
| Power service | Your utility | Get the utility on the calendar first, not last |
| Weather window | The season | Beat the ground freeze; order before it, not after |
WE CONTROL ~3 WEEKS OF THIS TABLE — THE REST IS WON OR LOST ON PARALLELISM
PLAINLY
We control 7 days plus 10–14. The rest is your site and your county — and the way to win it back is to run permits, site work, and the order in parallel, not one after another.
How long from order to growing?
The greenhouse itself is about 7 days to the truck and 10–14 days to assemble. The full timeline depends on your permits, site work, foundation cure, and power service — often the longer part of the schedule.
What's the most common delay?
Permitting and the pad. Permit approval is your jurisdiction's clock, and concrete cure time is non-negotiable. A PE-stamped plan set speeds the first; planning site work early speeds the second.
How do I speed it up?
Run the order, the permit, and the site work in parallel instead of one after another, and get your utility on the calendar early for any lit or climate-controlled build.
Lock the fast part today, and run the rest in parallel.
Price and order the frame in the build tool so its 7-day lead runs alongside your permit and your pad, not after them.
