Automatic Vent Opener - Gigavent
Automatic Vent Opener - Gigavent
Use on Coldframes or Greenhouses
Ingenious temperature-sensitive device that automatically opens and closes coldframe lids, greenhouse windows and even skylights. Works throughout the day and maintain a constant interior climate, something impossible to achieve by manual adjustments.
- Requires no batteries or electricity.
- It can be adjusted to start opening between 60-77ðF. Fully open at 86-90ðF. Fully closed at 55ðF.
- Strongly recommended for all our glazed season extenders because it dramatically improves plant growth.
- The hydraulic cylinder comes with a 1 year warranty. The average lifetime of the cylinder is 5-10 years, although some can last up to 20 years.
- Lifts up to 65 pounds
Replacement cylinders are available.
Screw directly into polycarbonate panels, wood, or metal frames. Do you have lighter loads to lift? Use the Standard Vent Opener to easily open windows and vents weighing as much as 32 lbs.
Note from the manufacturer: It is not necessary to remove the cylinders during the winter. Recommended to lubricate the piston rod yearly, this will help extend the lifetime of the hydraulic cylinder. Don't use solid grease, as dust particles "glues" easily onto the piston rod and can damage the rubber. Also do not forget to unlock the vent in the winter if leaving the vent openers installed. Even a even a weak winter sun can heat the hydraulic cylinder sufficiently to make it start pushing the piston rod outwards.

Let customers speak for us
I grow this in old litter boxes for a bunny & Guinea pig rescue- it is a great treat! Grows fast, thick and moist. I also grow it in my catio for my cats
High quality saffron corms that shipped when they said they would. They started sprouting in my cabinet within a week so definitely plant them quickly after receiving.
They looked good when the plants arrived. Waiting for planters to transplant so they'll have more room, but not planting in the garden to avoid the mint from spreading all over. They're still alive....
Beautiful seed garlic
This tree takes a lot of patience, both in years to fully fruit out and in terms of how late in the season the peaches finally ripen, - the end of September here in zone 5b, - but boy are they amazing when they come in! I have two other peach trees, - Redhaven and Reliance, which have wonderful fruit, but these Indian Free White peaches are amazing. The aroma alone is incredible. These also have thicker skins, more "fuzz," which you can rub off, and are a bit on the acidic side, but OH so yummy! I have gotten raves from the farmers who tried them.
Been using this for last couple growing season. Works wonders for the garden.
This hose gets dragged over bark and around raised garden beds, and also over concrete and a weedy hillside to water a couple trees. So far it has performed well and there aren't any leaks or kinks!
I have not had a chance to plant these yet as it’s still a little early. Package came quickly and garlic was beautiful, can’t wait to plant it.
This is a great addition to my veg garden area!
These branch supports work well, are sturdy, and relatively cheap. While you do have to provide your own poles, you can buy wooden or metal ones of your needed length at hardware or home improvement stores. We ordered ten at first and then bought ten more after seeing how the first ones worked.
Of course I wanted a hand made wooden trug, but they are expensive! This plastic one is easy to clean, and the perfect size. I love the drainage holes.
No lightweight nonsense here! These are the one of the industry standards in tree pots and they have become our go to on the tree farm. You will find lightweight look-a-likes out there, but most only serve one time use. These have held up for years and been used multiple times in some cases.
This has become one of my new favorites for all around propagation. From seeds to cuttings we use this mix for our fig trees and have had unbelievable success. The mix is formulated for strong and fast root development. No complaints about it!
These trays are great. Everything is ready to go.
I use them for cuttings and seed starting and haven't been disappointed yet.
I had the frustration of having my dog dig up my citrus trees and figs out of their containers. I was furious. This granular repellent has stopped the dog completely. So now, the dog can stay.
