Question 1

Are you a trading company or a manufacturer?

Accepted Answer

We are a factory. Our factory produces all items related to the greenhouse, so we provide the best price.

Question 2

Do you provide samples? Is it free or extra?

Accepted Answer

Yes, we can provide samples free of charge, but we don't bear the freight.

Question 3

How to get a quotation for the greenhouse?

Accepted Answer

Please let us know how many greenhouses are needed and what will be grown in the greenhouse so that we can suggest related systems.

Question 4

How should I choose a greenhouse system?

Accepted Answer

Please let us know where the greenhouse is (temperature, wind speed).

Question 5

How to assemble the greenhouse when purchasing?

Accepted Answer

We have professional after-sales service engineers who will provide planning drawings and installation manuals. You can communicate with him from time to time. If necessary, we can also send engineers to your country to supervise the installation of the greenhouse. Please send a message for specific details.

Question 6

How long does a plastic film greenhouse typically last?

Accepted Answer

Conventional PE film lasts about 1-3 years, while PO film or composite functional film can last 3-5 years. The frame (hot-dip galvanized steel) typically lasts 15-20 years or more. Actual service life is affected by local UV intensity, wind and snow loads, and routine maintenance.

Question 7

How often does the greenhouse film need to be replaced?

Accepted Answer

Replacement is needed when light transmittance drops significantly (film turns cloudy or white), large tears appear, or the anti-drip/anti-fog function fails (frequent water dripping inside). It is generally recommended to replace the film every 2-3 years to ensure adequate light and a good growing environment.

Question 8

How do you keep a plastic film greenhouse warm in winter?

Accepted Answer

The multi-layer covering.method is usually adopted: at night, cover the outside of the film with thermal blankets or straw mats; install a second inner layer (double layer) or small tunnels inside; set up an airlock at the entrance to prevent cold air drafts. If necessary, supplemental heating can be provided with warm air blowers or heating blocks.

Question 9

How do you cool a plastic film greenhouse in summer?

Accepted Answer

Mainly through ventilation and shading roll up the top and side films for natural ventilation;cover with an external shading net; use micro-spray irrigation or high-pressure misting for cooling. For multi-span film greenhouses, a wet curtain-fan forced cooling system can be installed.

Question 10

Which is better, a plastic film greenhouse or a glass greenhouse?

Accepted Answer

Neither is absolutely superior; it depends on your needs. Plastic film greenhouses have low cost, quick payback, and flexible construction, making them suitable for large-scale vegetable production. Glass greenhouses offer longer service life, lasting light transmission, and precise environmental control, but are much more expensive, making them ideal for research, seedling raising, or high-value flower cultivation. Film greenhouses are generally the first choice for growers.

Question 11

How strong a wind can a plastic film greenhouse withstand?

Accepted Answer

Standard designs typically resist winds of Beaufort Force 8-10. Wind resistance depends on the frame material (must be hot-dip galvanized), structural rationality (span and spacing), and the firmness of ground anchors. Areas with frequent typhoons require special reinforcement, such as adding diagonal braces and increasing tie wires.

Question 12

How do you deal with water droplets on the greenhouse film?

Accepted Answer

When purchasing, choose anti-drip film-its inner layer contains anti-fog agents that make water droplets slide down along the film surface instead of dripping. If an old film drips severely, spraying anti-drip agent defogger.can provide temporary relief, but the effect is limited; direct film replacement is recommended.

Question 13

Does a plastic film greenhouse require frequent maintenance?

Accepted Answer

Yes. Routine maintenance includes: promptly cleaning dust and snow from the film surface; checking that film tension wires are not loose; patching small holes (with special tape); inspecting the frame annually for rust; and replacing aging parts in time.

Question 14

What is suitable to grow in a plastic film greenhouse?

Accepted Answer

Almost all temperate crops, especially vegetables such as tomatoes, cucumbers, peppers, and leafy greens, as well as flower seedlings and edible fungi. With environmental control, off-season and summer cultivation are also possible.

Accepted Answer

This depends on the local winter temperatures and the crops grown. In warm southern regions, growing cold-tolerant leafy greens can get through the winter relying solely on thermal blankets and multi-layer film covering. However, in cold northern areas, or when growing temperature-sensitive high-value crops (such as tomatoes or flowers), nighttime insulation alone is often insufficient. Active heating equipment such as hot-air furnaces, hot-water boilers, or air-source heat pumps is required to
