Product Details
✓PASSIVE CO2 PRODUCTION - The Original ExHale CO2 Bag will provide a 4x4 foot or 128 cubic foot space with CO2 for up to 9 months, of which 6 months are peak production. This product is ideal for smaller grow rooms and grow tents that are looking to produce more CO2 and catalyze plant and vegetative growth.
✓EXPERIENCE A LARGER YIELD - Grow rooms, when used in companionship with the Original ExHale CO2 bag, can experience anywhere from 20% - 30% more growth. Requires no heat, electricity or complicated gear. Curated for indoor growers, hobby gardeners and greenhouse enthusiasts.
✓MAINTENANCE FREE - Place the ExHale bag slightly above the height of the plants in your grow space. CO2, being heavier than O2, will precipitate downward towards your plants. ExHale Original CO2 is a revolution in indoor CO2 production systems. Maintenance Free! Just CO2! Proudly made in the USA. Use it as a natural alternative to electric CO2 generators and equipment.
✓PERFECT FOR MOST PLANTS - ExHale can be used for both vegetative plant growth as well as for fruit and flower production. Put the ExHale CO2 Bag in your grow tent, and let it do its thing. Works best with controlled airflow and ventilation; optimal results in sealed or semi-sealed environments. A must-have for serious growers.
✓EASY-TO-FOLLOW DIRECTIONS - Remove hanger from bag. Fold the top of the bag over and re-attach the separation seam hanger by placing it above the filter patch. The Exhale bag can now be placed in your garden. Avoid compressing or folding the bag when hanging.
