The short version: Professor's Garden earns commissions when readers buy products through links on this site. It costs you nothing extra, and it never decides what we recommend.

Who we are

Professor's Garden is an independent product review publication covering garden tools, irrigation equipment, and indoor growing gear. We are not a retailer. We do not sell, stock, or ship any product mentioned on this site.

How we make money

This site is reader-supported. When you click a product link on our pages and complete a purchase, we may receive a commission from the retailer or the affiliate network that referred you. This is our primary source of revenue, and it is what keeps the site running and lets us publish our analysis without charging readers.

Affiliate programs we participate in

Professor's Garden is a participant in the following programs, among others:

Amazon Associates required statement

As an Amazon Associate, we earn from qualifying purchases. As an Awin partner, we may also earn a commission when you buy through links on our site.

What a commission does not buy

Editorial independence is the only thing that makes a review site useful, so we hold a few firm rules:

How to identify an affiliate link

Every affiliate link on this site is opened with a tracked URL and marked with rel="sponsored" in the page source, as required by search engine guidelines. You do not need to do anything differently — clicking an affiliate link and clicking a normal link works exactly the same way for you. The price you pay is identical either way.

If you would rather not use our links

That is completely fine. Copy the product name from any of our reviews and search for it directly. You will find the same item at the same price. Our recommendations are written to be useful on their own.

Questions

If anything about how this site is funded is unclear, or if you believe a recommendation was influenced improperly, please contact us. We would rather answer the question than lose your trust.

Written and reviewed by a horticulture lecturer

Every guide and review on this site is checked against published design and specification data by a horticulture lecturer who teaches plant propagation and nursery practice, and supervises undergraduate research in medicinal-plant cultivation. Where a claim cannot be verified, we say so instead of repeating it.
