🚀 Abunda's Overview

This is our summary and key points to consider based on customer reviews.


The product has received positive reviews for working effectively in controlling temperatures in greenhouses, opening and closing vents or windows as needed depending on the temperature. The ventilator mechanism is reported to function well and reliably with minimal adjustments, even in extreme weather conditions. However, some users noted that the instructions were vague and there were difficulties in getting the vents to close completely. There were also complaints about the lack of control over opening times in colder temperatures.

Pros

  • 👍Product performs effectively in various weather conditions.
  • 👍Automatically controls temperature within greenhouses.
  • 👍Minimal adjustments needed for operation.

Cons

  • 👎Instructions are reported to be vague.
  • 👎Difficulties in getting the vents to close completely.
  • 👎Lack of control over opening times in colder temperatures.

Should I Buy It?

If you need a reliable and automatic temperature control system for your greenhouse, this is a solid choice. Its functionality outweighs the minor cons of vague instructions and difficulty in getting vents to close completely, both of which could possibly be overcome with a little experience and effort. Therefore, this product is recommended for purchase.


  • Great replacement!
This hydraulic arm is an exact replacement for the one from the Costco greenhouse (Yardistry brand). I blew out the original trying to install it and thankfully this one fit just like the original! Install was easy and it is functioning perfectly!

  • Very adaptable
Adapted these to open/close louvered covers on a green house. Used 1/2” wide x 1/8” flat bar to connect them. Works great!

  • Works like the original
Got this as a replacement for the one I ruined while trying to collapse it when it was too warm out. A lot of companies sell these and they all appear to be the same design. Works well. Just install it when the morning is cool out, or leave in the fridge for half an hour beforehand.

  • Perfect
Color: Centre Shalf Opener
This works perfect for my green house. Opens when it gets hot. The temp is adjustable. Love this. Fix it and forget it.

  • Disappointed: Piston improperly sized, cannot adjust louvers to close
Louver vent opener (side mount version) does not close the louvers completely even at 50 degrees. The piston is incorrectly sized and wouldn’t even begin to close the vent when the temps fell to 80 and below. All my other vent windows had almost completely closed and these remained open . I have them “adjusted” as far out as the can possibly be screwed without unscrewing altogether. The only way to get the louvers to close at 50 degrees is to unscrew the piston completely. In all other respects the unit is a perfect fit for my louver windows. I grow plants that need the windows fully closed at 80 so that heat stays in all night long. So these are useless to me. I contacted the seller via their website via Amazon, but received no response. The build tool long enough that the 30 day Amazon return window has passed. So I guess I just have to uninstall and throw in the garbage. TLDR: don’t waste your money on the louver vent opener. ... show more

  • For the Harbor Freight 6 x 8 greenhouse
Color: Centre Shalf Opener
These work really well. It took little adjustments to get the vents to close all the way. These photos where taken when it is 70° F.

  • Works (kinda) with Climapod
Bought this for a Chinese made Climapod-Virtue. It works as advertised but I had to make adjustments to the bracket. The spine of the bracket protruded too far to allow the piston to completely close. I had to use a grinder to remove a large scallop of material from the aluminum spine. Once that was done, the piston was able to close all the way. ... show more
