When your extraction system is turned off a back draft shutter is the perfect way to stop air escaping from your room. It will also prevent unwanted cold / hot air from coming back into the grow room when it is not wanted. A Back draft shutter is a cylinder shaped piece of equipment with 2 centrally mounted flaps. The air produced by your duct fan will cause these flaps to open, however when the duct fan is turned off the flaps will shut meaning no air can come in from outside.

Boost Buddy is a product for the application of CO2 in growing spaces measuring 1.2 x 1.2 meters or less.
It does not require electricity or maintenance, it just hangs inside the growbox and continuously emits CO2 (it is recommended to remove it at night).
The difference between Boost Buddy and other similar bags is that Boost Buddy generates 5 times more CO2 thanks to its own unique blend of ingredients and a bag with a larger breathable surface.
Boost Buddy can be used for 6 months (2 harvests) and then it can be used as garden compost, because all 15 ingredients are completely organic.
Can-Fan Digital EC Fan Controller full feature environmental control Can Fan introduces LCD EC Fan Controller, an advanced climate controller with LCD Screen, that allows you set temperature and humidity, besides other interesting functions like hysteresis, negative pressure, maximum and minimum speed of CAN Fan EC extractors. The Can Fan EC Controller works only in conjunction with Can Fan EC extractors, built with most modern technology, being more energetically efficient, and guaranteeing more power and less electrical consumption. • Temperature day • Temperature hysteresis day • Humidity day • Humidity hysteresis day • Minimum speed day • Maximum speed day • Temperature night • Temperature hysteresis night • Humidity night • Humidity hysteresis night • Minimum speed night • Maximum speed night • Negative pressure setting • Switch sensor level • Switch over time day/night
This satellite controller runs AC fans using a stepped transformer linked into the LCD controller. This means the EC controller can run AC fans as well
