Frequently Asked Questions

What is hydroponic farming?

Hydroponics: The “hydro,” or “water,” is key to growing in this form. Hydroponic farms do not use soil but do have a growing medium, such as Rockwool. Hydroponic plants need nutrients and can be grown in vertical racks, towers, or vertical panels.

Who is the Flex Farm for?

Fork Farms believes that anyone can be a farmer. The Flex Farm is for anyone with a desire to grow highly nutritious, chemical-free, fresh food year-round, indoors. Its compact size and high yield capacity make it the perfect fit for educational institutions, culinary operations, healthcare organizations, nonprofits, families and more. Indoor farming is revolutionizing the way we bring fresh and healthy food to our communities.

What can I grow in a Flex Farm?

The Flex Farm is optimized to grow all varieties of leafy greens such as lettuces and culinary herbs. Our partners have seen success growing cucumbers, strawberries, peppers, tomatoes and even pumpkins. Imagination and experimentation are the keys to unlocking the full potential. We’re still making discoveries ourselves!

How many pounds of food can I grow in a Flex Farm?

That all depends on what you plant! Some plant varieties weigh more than others. It also depends if you are growing leafy greens, herbs, or fruiting plants such as strawberries and tomatoes. Overall, we say a Flex Farm has the capacity to grow more than 20 pounds of leafy greens every 28 day grow cycle.

How much time does it take to maintain a Flex Farm?

On average, you can expect to spend about 1 – 3 hours per month maintaining your Flex Farm. This includes the time it takes to plant seeds, transplant your seedlings, and harvesting.

Where can I find other seed varieties?

If you are interested in purchasing additional seeds, Johnny’s Selected Seeds is a reliable source for a wide variety of high-quality seeds. We highly recommend using pelleted seed whenever possible. Pelleted seeds are easier to handle and the clay coating provides extra moisture to the seed so it doesn’t dry out.

Do you provide fundraising for nonprofits?

Absolutely! We are experienced in helping organizations connect with funding opportunities. We offer a Philanthropy Tool Kit and fundraising assistance for qualifying organizations. Contact us at

Why did Fork Farms stop shipping 35% concentrated hydrogen peroxide? How does this impact cleaning and growing instructions?

We recently found through testing that use of 35% hydrogen peroxide has minimal impact to keep your Flex Farm clean and reduce algae growth. We stopped shipping this product effective September 6th, 2021, to reduce our environmental impact through shipped plastic, and to provide a safer and cleaner growing experience.

Please follow the deep cleaning instructions in the Grow Guide using a 3% hydrogen peroxide solution available at most drug and grocery stores. There is no need to dilute the 3% solution; simply spray or wipe onto your Flex Farm to clean. For growing, we no longer recommend adding hydrogen peroxide to your water supply during the growing cycle.

If you have been using 35% hydrogen peroxide, please note that you can continue to use this safely by following previous recommendations. We suggest replacing it with a 3% hydrogen peroxide once you run out for cleaning purposes and discontinuing the addition of hydrogen peroxide in your water supply.
