Greenhouse accessories are not optional extras. They control the environment when outside conditions change rapidly. A properly vented greenhouse prevents fungal disease and heat stress. A correctly anchored base frame resists wind uplift. Shade cloth reduces leaf scorch during summer, while heating cables keep propagation trays warm in early spring. When accessories are poorly matched, the greenhouse frame itself can suffer from condensation, rust, or structural movement. YS STEEL accessories are built from galvanized steel, UV-stabilized polymers, and corrosion-resistant hardware to last as long as the main structure.
YS STEEL offers a full line of greenhouse accessories organized around five core functions: structural anchoring, ventilation, shading, irrigation, and internal organization. The following list summarizes the main product categories and their intended use.

Selecting accessories should start with a clear understanding of your local climate, crop type, and greenhouse size. The following checklist helps growers match accessories to real needs.
The number of automatic vent openers depends on the total roof vent area and the weight of each vent. As a general rule, one opener supports a vent weighing up to 15 kg. For a standard 6 m × 3 m hobby greenhouse with two roof vents, two openers are usually sufficient. For larger greenhouses, install one opener per individual vent frame. If the vent is longer than 1.5 m, use two openers mounted at opposite ends to prevent twisting. Always check the opener’s stroke length and mounting bracket position so the vent can open at least 30–40 cm at peak temperature. In very hot climates, combine automatic openers with side louver windows to increase total airflow.
The best anchoring method depends on your foundation type. For soil installations, use hot-dip galvanized ground anchors driven at each corner and every 1.5 m along the base rails. The 600 mm length is recommended for loose or sandy soil, while the 400 mm length works in firm clay. For concrete foundations, use galvanized base plates bolted into the concrete with M10 or M12 anchor bolts. If you live in a high-wind area, combine both methods: set base plates into a concrete curb and add ground anchors at the corners. Always tighten all bolts after installation and re-check them after the first strong wind event.
Yes, shade cloth can be installed inside the greenhouse, but the effect is different. External shade cloth blocks solar radiation before it reaches the glazing, which keeps the entire structure cooler. Internal shade cloth still reduces light intensity but allows the glazing to heat up first, so the cooling effect is less dramatic. Internal shade cloth is useful in cooler climates where you want to diffuse light without losing too much heat. YS STEEL shade cloth works for both methods because it is lightweight, UV-stabilized, and has reinforced edges for clip-on installation. For maximum summer cooling, install the cloth outside with a small air gap between the cloth and the glazing.
Watering frequency depends on crop type, pot size, temperature, and growing medium. As a general guide, most greenhouse vegetables need water once per day in cool weather and two to three times per day in hot weather. Drip systems with 2–4 L/h drippers usually run for 15–30 minutes per cycle. The goal is to moisten the entire root zone without water draining from the bottom of the pot. Check the soil moisture at root depth before increasing frequency. In high temperatures above 30°C, run additional short cycles rather than one long cycle to avoid waterlogging. Always use a pressure regulator and filter to keep dripper flow consistent.
Yes, in most cases a circulation fan is still beneficial. Roof and side vents create passive airflow that moves warm air upward and out, but they do not always move air horizontally across the plant canopy. A circulation fan keeps the air mixed so temperature and humidity are uniform throughout the greenhouse. This reduces cold spots near glazing and damp pockets between dense plants. Use one fan per 20–30 m² of floor area, mounted above head height and aimed slightly downward. Run the fan continuously during the day and periodically at night if condensation is heavy. The fan uses very little electricity compared with heaters or exhaust fans.
