Smart Grow CO2 Bags Hydroponic Tent Room CO2 Generator - Greenhouse Plant Growth Like Exhale Grow Bloom (1)

Great quality, fast delivery

my dad likes them i got them for him

I followed instructions, made a few holes along the top of the bag and hung it at canopy height with a rotating fan beside it for circulation.I noticed no increased growth compared to my identical setup (same light, nutes, strain, schedule) without CO2 (the one without CO2 was actually bigger).I checked and saw that a small amount of water should be added to the bag and that may kick things off, but I still saw no difference.Can't really recommend them.

If you don't have these in your grotent you are letting your plants down. They don't cost a lot and will make your plants flower much better.

My plays died wasting 9 weeks of work. After just 4 days of this trash being put in my tent. This does not work!!!.. NOT CO2

I don’t know because I read your reviews and a few not very good ones😳 but I believe in giving things a chance I’ll re edit in a month depending on outcome 👍🏻

better than 35£ exhale
