Light Dep and Roll Ups

Greenhouse ventilation is influenced by many factors, the objective is to hold the temperature in the optimal range for the crop. Steady temperature can be achieved, year-round, with a combination of: roll up greenhouse sides, HAF fans, thermal openers and roll up motors.
Chain pull cranks are used as a manual opener for rack and pinion vents, light deprivation and blackout systems.

Use tubelock with motorized systems (because of the added torque); and for roll up roof vents (together, tubelock and tube create a very straight combination).

Attach the poly to the roll up tube with tubegrips (24" apart) for sidewall applications with manual drives (inline and gear cranks). Inexpensive, fast and easy to adjust - 32 mm works with 1-3/8" tube.

Roll Up Motor, partial install kits for Venting

Price: $15.75

Hardware to install the roll up motors for a venting application.
Tubes supplied by the customer.

For houses made with 1-3/8" tube:

Ideally, the threaded-connector is installed 1 foot above the top of the roll up wall - this will allow the fullest opening. The loose-end must be very close to grade - so the wall can fully close.

The threaded-connector sits between the arch and the springwall base - to do: un-attach the poly; partially raise a screw and wiggle the bracket in place.

The1/2" EMT can either be drilled, as the tube below - or you can tap a brace pin in. To install a brace pin slightly ovalize the end of the tube with vice grips or a vice; brace the tube against something solid and tap the pin squarely (so as not to bend the pin over) till it is snug.
