Frequently Asked Questions

AI
Yes, but they are best for extending seasons or protecting hardy plants. For extreme cold, ensure the model has a thick, insulated PVC cover and consider adding supplemental heat sources. Indoor models with grow lights are ideal for seed starting during winter months.
Wheels are highly recommended for mobility. They allow you to move the structure to sunny spots or bring it indoors during storms. Look for swivel casters with locking brakes to ensure stability once positioned, preventing accidental movement in windy conditions.
If you are starting seeds indoors or growing in low-light areas, a built-in grow light is essential for preventing leggy, weak plants. For outdoor use in summer, natural sunlight is usually sufficient, making lights an optional but useful upgrade for year-round utility.
