Many growers use both: plastic hooks to run growing wire along the frame for vining crops, and metal hooks to hang fans, baskets, and equipment. They work together in the same frame channel system.
How to Set Up a Growing Wire System
- Install plastic hooks in the Riga frame channel at the desired height and spacing along the length of the greenhouse
- Run growing wire or twine through or over the hooks to create a horizontal support line
- Train vining plants (tomatoes, cucumbers, beans) up vertical strings or clips attached to the horizontal wire
- Reposition hooks as needed to adjust wire height as plants grow taller
Frequently Asked Questions
Which Riga models are these hooks compatible with?
The plastic hooks are designed for Riga greenhouse models that feature the frame channel system, including the Riga IIs, IIIs, III, IVs, IV, V, and XL series. Contact us with your model number if you are unsure whether your greenhouse has the compatible channel.
What is the difference between the plastic hooks and the metal hooks?
The plastic hooks are specifically designed for running growing wire or rope to support vining plants — they hold a wire or twine line horizontally along the frame. The metal hooks are designed for hanging heavier items like plants in pots, fans, grow lights, and tools. Both install in the same Riga frame channel. Many growers use both types in the same greenhouse for different purposes.
What type of growing wire or rope works best with these hooks?
Standard greenhouse growing wire, galvanized wire, or heavy-duty garden twine all work well with these hooks. For tomatoes and cucumbers, 14–16 gauge galvanized wire provides good support. For lighter crops like beans or peas, heavy-duty twine is sufficient.
How many hooks do I need for my Riga greenhouse?
For a single wire run along the full length of a Riga V (17'6"), spacing hooks every 2–3 feet would require approximately 6–9 hooks per wire run. One package of 10 hooks is typically sufficient for one or two wire runs in most Riga models. For a fully equipped growing system with multiple wire heights and rows, 2–3 packages gives you maximum flexibility.
Can I use these hooks with non-Riga greenhouses?
These hooks are designed for the specific channel profile of Riga greenhouse frames. They may not be compatible with other greenhouse brands that use different frame profiles. Contact us to verify compatibility with a specific non-Riga frame before ordering.
