Frequently Asked Questions
Should I choose clear or green-tinted tarps for autumn seedlings?
Clear tarps maximize light transmission and are best if your seedlings need as much photosynthetic light as possible. Green-tinted tarps slightly diffuse light and can reduce hot spots; they work well if you want a little light diffusion while still boosting warmth during cool fall nights.
How thick should a tarp be to protect seedlings from cold nights?
For reliable overnight protection and seasonal reuse, look for 14–20 mil PVC. Thicker tarps trap more heat and resist wind. For short-term or emergency use, 6–12 mil polyethylene is acceptable but offers less insulation and durability.
How do I prevent condensation and mold under a clear tarp?
Provide daytime ventilation—open the ends or lift one side when temperatures rise—to reduce humidity. Use breathable staging (raised trays, gravel) and avoid overwatering at night. If condensation is persistent, add a small passive vent or periodically remove the cover on warm days.
