## Frequently Asked Questions

### How do I download the PDF after purchase?

You can download the PDF right after checkout from the download link on the order confirmation page and in your confirmation email. Save it to your device so you can print or open it any time.

### How much does it cost to build an 8x12 greenhouse from these plans?

The cost to build an 8x12 greenhouse depends on local lumber and polycarbonate prices. The plan includes a complete shopping list with quantities, so you can price every item at your local store before you start.

### What is the best wood to build a greenhouse?

This wooden greenhouse uses pressure-treated lumber for the frame, rated ground contact for the base, and cedar for the knee walls, fascia, doors and bench slats. Cedar resists moisture well and the plan recommends a clear penetrating oil to protect it.

### Should a greenhouse be located in full sun or shade?

A greenhouse should be in the sunniest level spot you have, out of the drip line of trees. Where you can, run the long sides east-west so one roof slope faces south.

### What skill level do these 8x12 greenhouse plans require?

These 8x12 greenhouse plans are rated intermediate and need 2 people. Most builders finish in about 4 weekends.
