ExHale CO2 CO2 Bag, XL, 288 Cubic Foot Space

Used in a 5x5, actually a bit oversized for that need. Product is super though.

The ExHale CO2 system is exactly what I needed for my indoor grow tent. I needed to raise the CO2 levels in my grow tent, but was hesitant to purchase a full mechanical system or use a flame based system indoors. The ExHale back works perfectly since the fungus is light activated. The CO2 levels rise in the tent as the plants begin to wake up and does down once the lights go out. I have a 6X4X6 tent and this thing can raise the CO2 levels to 1600 PPM easily. I was initially worried about them being that high and found just placing it in a slightly shadier spot was enough to lower them back to a more acceptable level.

Prodotto non funzionante, già usato e completamente consumato.

Das Produkt mag funktionieren jedoch nicht wenn der Verkäufer fast abgelaufene Ware versendet!!! Myzel ist grau und kaputt der ganze obere Teil feucht …. Frechheit

Just a note since as it doesn't state it anywhere. The product came activated. The bag had holes and the mycelium was seeping out of the bag. Bag was also missing hanger. Not worth the hassle to go back and forth with shipping. Will tape wholes and use as is. Product works since it's not my first time using it. Best to buy it local and make sure you are getting it with a hanger and no holes.
