ExHale CO2 Bags

A continuous shower of CO2 directly onto your plants.

No Activation Needed – Place The Bags & Wait For The CO₂ To Begin!

These revolutionary carbon dioxide production systems are designed to be maintenance-free. Simply place the bags slightly above the plants in your grow room to allow carbon dioxide to precipitate down onto the cultivated plants. ExHale CO₂Bags utilize natural processes of beneficial fungal mycelia to cultivate carbon dioxide for up to 6 months! Increase CO₂ levels to stimulate photosynthesis and increase vegetative growth and crop yields.

Plants growing under artificial light indoors often lack enough carbon dioxide to efficiently photosynthesize. Maximizing the process of photosynthesis is imperative for indoor growers and results in larger plants with greater yields. Use in vegetative and flowering stages for increased canopy size, faster growth and prolonged production during budding. Increasing CO₂ levels can also help plants tolerate higher temperatures in grow rooms using bright lighting.

ExHaleCO₂ Bags produce carbon dioxide 24 hours a day with no need to refill bottles or install carbon dioxide production units that tend to be expensive and maintenance heavy. Bags come ready to use and should be placed as soon as possible after delivery. Please call us at 1-800-827-2847 with any questions you have about bag placement, CO₂usage or usage rates.

Recommended Uses By Size:

ExHale Micro – Use in clone domes and seed trays to stimulate root development in starter plants.
ExHale Original – Designed for small to medium sized grow spaces.
ExHale XL – Designed for use in medium to large growing areas.
ExHale 365 – Designed for use in areas that need prolonged CO₂ production. Once activated, it provides CO₂ for 9 months.

MODEL	GROW SPACE	CO2 PRODUCTION TIME
Micro	3.5 cu ft	3 months
Original	128 cu ft	6 months
XL	288 cu ft	6 months
365	Area needing prolonged CO2 production	9 months (3 weeks to build up to peak CO2 output)

Exhale Micro

The Exhale micro does not come with a hanger.
Place Exhale micro in the center of your cutting or seedling tray and cover with clear dome.

Exhale Original & XL

The Exhale Original and XL Exhale are pre-inoculated.
These models are delivered with the hanger below the filter to block the flow of CO2.
When ready to use, remove the hanger to allow CO2 to flow. Reattach hanger ABOVE filter.
Hang or place in your tent or grow space immediately.

Exhale 365

The Exhale 365 requires inoculation before use.
Remove the Separation Seem/Hanger and allow the spawn material to fall to the substrate. (You may have to gently guide the spawn)
Reattach the Separation Seem/Hanger ABOVE the filter.
Place or hang in greenhouse or grow space.
The Exhale 365 takes about 3 weeks from inoculation until peak flow of CO2.

General Information

Place ExHale slightly above the height of the plants in your grow space. CO2 being heavier than oxygen will precipitate downward towards your plants.
You will notice a change in the appearance of the mycelial mass. Overtime it will take on a whitish look, which is normal. CO2 will continue to be produced for up to 6 months.
The bag may inflate in certain conditions; however, this is not an indication of performance. If the mycelium is growing, then the CO2 is flowing.
Exhale CO2 Bags can be added to compost piles/bins after use. Simply remove the contents of the bags and mix into compost. The bag can be recycled through your local plastic recycler.

CO2 bags

Sep 23, 2023 | By Jonathan McRee

What can say they work, circulation and timing make big improvements.

Think it already went through the process before using

May 24, 2023 | By Joseph Aquino

Up your CO2 game on a budget

Mar 30, 2022 | By Danzel

If you're short on space, or don't feel able to shell out for pressurized CO2 (me), this will give you the boost you're looking for for your next two or three grow cycles. My only complaint about this product is when I went to compost it and use said compost, there's a possibility it gave my soil a really intense root fungus that kills off all my aliums.

Worst bag go with a bigger one

Excellent service, prompt delivery, highly recommend

Underwhelming

Jul 18, 2021 | By Alex Reznik

Maybe I was unlucky and received a bad bag, but thee bag came all white and hard as a rock. It has been hanging for 3 weeks and see almost no change in the co2. Product might work but maybe I just got a bad bag.

Best Exhale that I have bought

May 31, 2021 | By Bill C

Product arrived in VERY good condition compared to purchases from other sites. Highly recommend this site for a fresh product. Will buy again. Price is also good in comparison, too.

Best price, fresh product, super fast shipping!

May 2, 2021 | By Jennifer Castro

This product was much cheaper than anywhere else and it felt good to purchase from a "non Amazon' store. A+++++++++++++++

For your small inside grow, using these recyclable CO2 producing bags is a no brainer!

Co2 product

Apr 12, 2021 | By Dennis Day

High-quality product that works! Fast shipping.

Works wonders

Apr 9, 2021 | By Roc

I had a rhododendren that looked like it went through the apocalypse. I gave it 12oz of recharge and 3 days later it had 4 more branches and grew over 3 inches. 2 weeks later the thing bloomed and o gave it to my mother for easter. I plan on using this stuff on my garden this summer and I'm excited to see the results

good stuff

Feb 16, 2021 | By Mae B

oops, ordered the wrong size, meant to get the regular. But these little bags seem to be puffing out the CO2! Really like this natural, effective product. So very easy to use, no mess, low plastic content, compostable after use, using the natural synergy of the fungi and the plants- so neat! My plants have much greater yields. Definitely pays for itself in one season.

Feb 8, 2021 | By toby harris

very good product performed wonderful

Nope

Feb 4, 2021 | By Da Grower

Barley gets my room over 500ppm and I mean barley. Never get my money again. Invest in a tank and reg. Not a believer.

defencies

Jan 31, 2021 | By Larry Jackson

When growing your herbs, greens, veg. & fruit in a grow tent Exhale will help with co-2 deficiencies..

Yay fungi!

Jan 12, 2021 | By Meghann

I've only had these hanging for a few days, but my plants do look perky and happy. I think it's working already. I really like this low plastic, natural product that can be composted after use. Fugus is so amazing to me, these bags are so interesting! Though they were a bit pricey, it's worth a lot to me to see the bags function- like a science experiment! Glad the containers are clear plastic, so I can see what's going on in there. If they really boost plant production, this will be a great buy- will re-review in a couple months. They were so easy to hang in my grow room, right over the plants.

Owner Response: Glad you're happy Meghann! Mark your calendar to know when to consider replacing it. Depending on the size of the Exhale, there is a length of time it will produce CO2.

Co2 bags

Ordered two co2 bags at good price and fast shipping will definitely be ordering again

Possible expired bag upon arrival

Dec 15, 2020 | By Sandra Morgan

I ordered the Co2 bag and it was completely white when it arrived. I heard that means it's old.

A tale of 2 Fungus; fungi?

Oct 27, 2020 | By Daryl Klinger

Ordered a bag of ExHale from Arbico and another from un-named "A" online retailer. Not only did the Arbico order arrive early (in spite of their own warnings of Covid delayed mail deliveries), the ExHale we received from Arbico looked better all around; from packaging to product. Know where we'll be getting our garden supplies from going forward. The ExHale it self delivers as promised, noticed a difference in plant growth and (to quote the 1920's), "vitality" in no time. Strongly recommended for any indoor garden.

My plants know I love them now!

Oct 22, 2020 | By Peter Kalazdy

First.... Thanks to all the people working hard to Design/produce/package/ship me this product in the middle of this Pan-insanity! 1000-1300 ppm after 6 weeks of "brewing". This thing is PERFECT! I will purchase more, and thanks again.

Love these bags

Oct 12, 2020 | By FoolishBeast

I have used these from day one. and will use these till the end. gives my plants that little extra boost that they need in the winter time. my green peppers look great, and my dwc lettuce even better. way safer than a tank.

Sep 11, 2020 | By Larry Fowler

ExHale Bags

Jun 30, 2020 | By Kevin Strocher

Was easy to order and pay for, I thought the wait to receive them was a bit long but with everything going on in the world these days I am not complaining , seriously. they were what I expected and they seem to be in fresh good order so I put them to work.

Co2 bag

Jun 10, 2020 | By Randy Kuschel

I am not happy with the bag I received. The last bag I bought from you prior to this one helped bring my levels around 1250 ppm and this one I only get to 550 ppm and the color is different than the good bag

Great product

Ordered the XL

May 11, 2020 | By Rich Myers

I ordered the bug bag, I did receive the regular one, sent a simple email asking if I ordered the wrong one by mistake. The manager responded very promptly stating they just sent the wrong one and to keep the regular bag to get me by and the xl was sent and I got it a few days later. Thank you I will order again, most places make you feel like it's your fault.
