ExHale CO2 EX50002 Exhale XL CO2バッグ | 二酸化炭素濃縮、栽培テント用XL CO2、6ヶ月、5kgの生産促進。 (1パック)

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

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

Perfect like usual

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.
