Give your plants more oxygen
AirDome is designed to increase the air available around the root zone. If you are lucky enough to have power in your greenhouse you can increase your yields by up to 130%
The AirDome is placed at the bottom of the pot when potting up. Best results are obtained by using a substrate that is "light and fluffy" such a 50:50 coco : perlite or clay ball mix that will capture the air in pockets. Nearly cover the AirDome with pH stable clay balls or perlite up then place the substrate over the top. Let the plant establish for approximately 10 days then turn the air pump on.
Ideally use the AirDome only during the day and use only warm air. You can pulse the air through or use a continuous gentle flow. Ideally raise the air pump above the level of the AirDome to ensure there is no backflow of water.
