What size bag do I need? And other questions, answered.

3-gallon bags are great for herbs and flowers. 5-10 gallons are perfect for tomatoes, peppers, and root veggies. Use 20-gallon bags for larger plants like potatoes or fruit trees. Pick your size based on plant size, growing location, and watering needs.

Yes, especially for root health. Plastic traps moisture and heat, which can cause root rot or root binding. Our non-woven fabric grow bags allow for natural air pruning and faster drainage, keeping roots cooler, drier, and healthier.

Definitely. Humboldts Secret Fabric Grow Bags are ideal for indoor growing when paired with a saucer or tray to catch runoff. Customers love them for balconies, greenhouses, and even grow tents. Just water mindfully, as the breathable fabric drains faster than ceramic or plastic pots.

Many of our customers report getting 2–3 full seasons or more out of each bag. The thick, non-woven fabric resists tearing, and the reinforced handles stay secure even under weight. At the end of each season, just rinse and dry them before storage.

Yes, though we recommend refreshing your soil between seasons, especially if you're rotating crops. The bags themselves rinse easily, making seasonal reuse straightforward. Add compost or amendments for best results.

Yes. Humboldts Secret Fabric Grow Bags are made from breathable, plant-safe fabric with no synthetic coatings or chemical residues. They're widely used for tomatoes, greens, potatoes, herbs, and other edible crops.

We prioritize quality. Thicker fabric, tighter stitching, better airflow, and stronger handles mean you get more seasons out of every purchase. And we have hundreds of reviews to prove it.

Yes, and that’s a good thing. The fast drainage prevents overwatering and reduces root disease risk. You may need to water slightly more often, but your plants will grow stronger because of it.

Bags that outlast the season — and outgrow the rest.

Our bags are built for gardeners who want more than a container. They want roots that breathe, soil that drains, and harvests that thrive.

No root rot. No soggy soil. Just healthier plants — and more freedom how and where you grow.
