Maximize the efficiency and comfort of your HR15/HR50 humidifier with our Digital Humidistat. Enjoy precise control over humidity levels and optimize the performance of your humidifier. Objective and informative, this professional-grade device ensures a healthy and comfortable atmosphere in your home.

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.

The Grand Daddy Pad or GDP is our largest and strongest Green Pad CO2 Generator. With the power of 4+ Original Green Pads and now an even better value.

Use the GDP's for larger gardens, use 1 GDP for each 22 cubic metres.

Use just like The Green Pads (Hang Spray and Walk Away!) but new GDP's are added every 10-12 days and leave in the oldest GDP's for up to 20-days (or more). With 2 Grand Daddy Pads in each pack you have as much CO 2 power as 8 + Green Pads. For drier climates and to keep Green Pads activated, simply add a moist sponge to a folded Green Pad. Great for gardeners who are using lots of Green Pads and now for larger grow rooms too.

And of course keeping a pack or two of these on hand for when your tank runs out or to make your tanks lasts longer or to use when you don't want the heat of your gas generators is a great idea!

Contains 2 Pads.

Acoustic Ducting A high quality, flexible aluminium ducting with a perforated inner layer and an acoustically transparent plastic layer to encapsulate the fibreglass. The noise reducing insulation limits break-out noise from the duct and acts as a fan silencer. For best results use on both the input and output sides of your extractor fan.

The Science of CO2 Enrichment

Carbon dioxide (CO2) is a critical component in the process of photosynthesis, the biochemical pathway that allows plants to convert light energy into chemical energy, which is stored as sugars and other organic compounds. During photosynthesis, plants absorb carbon dioxide from the air and use it to produce glucose and oxygen. When CO2 levels are elevated, plants can perform photosynthesis at a faster rate, leading to increased growth and yield.

In a controlled indoor cultivation environment, maintaining an ideal CO2 concentration is essential for maximizing plant growth. Typically, outdoor air contains around 400 parts per million (ppm) of CO2, but fruiting plants especially can benefit from higher levels, ideally between 1,000 and 1,200 ppm. By increasing CO2 concentrations in the cultivation area, growers can optimize photosynthesis and, in turn, enhance the plant's development.

Benefits of Growing with CO2

1.Increased Photosynthesis: As mentioned earlier, elevated CO2 levels stimulate photosynthesis, allowing plants to capture more light energy and convert it into biomass. This leads to faster growth and larger, healthier plants.

2.Enhanced Yield: A direct result of increased photosynthesis is higher yields. Growers who implement CO2 enrichment can expect more bountiful harvests, ultimately increasing their profitability.

3.Improved Quality: Not only does CO2 enrichment boost quantity, but it also enhances the quality of the crop. Plants grown with higher CO2 levels often produce denser buds, increased trichome production, and improved potency.

4.Faster Growth Cycle: CO2 enrichment can shorten the time it takes for plants to reach maturity. This can be particularly advantageous for commercial growers looking to optimize their production cycles.

Implementing CO2 Enrichment

1.Monitoring and Control: Accurate monitoring of CO2 levels is crucial. Use a reliable CO2 monitor or controller to maintain the desired concentration. Aim for a range between 1,000 and 1,200 ppm, but be cautious not to exceed 1,500 ppm, as higher levels can lead to diminishing returns and potential health risks for growers.

2.Proper Ventilation: To ensure that CO2 is distributed evenly throughout the growing area, you'll need efficient ventilation and airflow systems. This helps prevent pockets of stagnant air and ensures all plants receive the benefits of CO2 enrichment.

3.Ensure that grow room temperatures are kept between 28-32 degrees C, especially when growing with LED lights this will help ensure the leaf temperature is kept above 24 degrees. This consistent temperature will enable the leaf’s stomata to transpire correctly.

4.Feeding plants grown under LED lighting using CO2 will need higher EC levels due to the plants increased metabolism.

5.Timing: CO2 enrichment should be implemented during the light period of the plant's growth cycle. Typically, this means providing CO2 for 12-18 hours a day when the lights are on. Monitoring and controlling CO2 levels during the dark cycle is unnecessary and wasteful.

6.Safety Measures: Safety should always be a top priority when working with CO2. Ensure proper ventilation, use certified equipment, and follow manufacturer guidelines for CO2 storage and handling. A dedicated CO2 monitor and alarm system can provide an added layer of security.

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.
