How to Grow Red Potatoes in Your Grow Tent?

That’s a great idea! Red potatoes can definitely work in your grow tent, especially if you have deep enough containers. Growing them in a 1' x 2' cardboard box (or something similar) is totally doable, but you might want to consider a more durable container like a fabric grow bag or plastic tote to handle moisture better.
How to Grow Red Potatoes in Your Grow Tent
✅ Container Choice
- Size: At least 12-16 inches deep and 1-2 feet wide per plant.
- Material: Fabric grow bags (5-10 gallons) or plastic bins with drainage holes work better than cardboard (which can break down over time).
✅ Soil & Planting
- Use a light, well-draining mix (potting soil + compost + perlite).
- Start with 2-3 seed potatoes per square foot, spacing them evenly.
- Cover with 4 inches of soil, then add more soil as they grow (hilling method).
✅ Light & Temperature
- LED Grow Lights: Keep them 12-18 inches above the plants.
- Light Cycle: 12-16 hours per day.
- Temperature: Best between 60-75°F.
✅ Watering & Care
- Keep soil moist but not soggy (potatoes hate sitting in water).
- When plants reach 6-8 inches tall, add more soil around the stems (hilling) to encourage more potatoes to grow.
- Harvest after the leaves turn yellow and die back (usually 8-10 weeks after planting).
Since your tent is only 5’6” tall, you’ll want to place the potato container toward the bottom to leave space for taller plants like cucumbers and beans. Would you be growing them alongside your other plants, or dedicating a section of the tent just for potatoes?
