FAQ
Q1: How to choose between the three materials of PS, PET, and PP?
PS: High hardness, good molding, high cost-effectiveness, suitable for short-term seedling cultivation and one-time use, preferred for universal use.
PET: High transparency, strong toughness, low temperature resistance, suitable for tissue culture, cutting, and scenes that require observation of root systems.
PP: High temperature resistant, anti-aging, repeatable, suitable for long-term multiple use, large-scale seedling cultivation in greenhouse.
Q2: What are the suitable situations for perforated and non perforated trays?
Perforated: drainage and breathability, preventing root rot and sudden collapse disease, suitable for soil cultivation, substrate seedling cultivation, outdoor/spray seedling cultivation.
Non porous: Water and fertilizer retention, suitable for hydroponics, nutrient solution seedling cultivation, tissue culture, experimental control, and short-term seedling cultivation.
Q3: Is the size standard and can it be adapted to seedbeds and automation equipment?
Adopting industry standard flat rectangular dimensions, the surface is flat with small tolerances, perfectly matching standard seedbeds, seedling racks, heating pads, seeders, transplanters and other automated equipment, supporting batch stacking and assembly line operations.
