CO2 removal from mushroom growing tent
Stratification
Best of all, use no chemicals. If you have an air circulating fan in your chamber, use it intermittently. When not running, ambient air enters small hole(s) at the top of your chamber, and carbon dioxide will escape out small hole(s) at the bottom of your chamber. CO2 at standard temp/press is invisible, but it definitely will sink beneath the unmoving oxygen and nitrogen of ambient air.

You should probably expand on this to address the OPs query. As it stands, its borderline NAA.More

Please stay away from sodium hydroxide, it's way too nasty to use in non-lab setup. You can handle it safely in dry conditions, but in contact with water, it becomes sticky and causes bad burns.
As a substitute, I suggest $\ce{Ca(OH)_2}$, readily available as slaked lime. You can structure it into relatively high-surface sculptures and it solidifies into common plaster upon binding enough $\ce{CO_2}$. It is often used for this purpose due to its low price, low toxicity and ease of handling.
In your situation, I would just put some vertically fixed mesh soaked in very viscous suspension of calcium hydroxide. In the high humidity conditions you'd have no problems with normal drying, so once it solidifies it has done its job and you can just hit the mesh against the ground to crumble the plaster away and put on new layer. It is advisable to use gloves and goggles, but it is not as necessary as it would be in the case of sodium hydroxide (look at all the masons around).

Actually, the vertical mesh setup doubles as a humidifier! I tried to use a large piece of textile soaked in thick calcium hydroxide slurry. If it was kept humid, no other means of humidification were needed. No ventillation was used beside accidental, and the oysters looked much better. Since the system is pretty much closed, only a little humidity escapes. (The reaction itself produces a small amount of water too, although probably it does not matter much.) Thank you for the suggestion!More

If your chamber was small enough, you could try having racks of germinating seeds. As they sprout they would be absorbing a minuscule amount of co2. They wouldn’t need light. If you’ve ever made sprouts in your kitchen cupboard this can be easily achieved. I am going to try this. Sunflower would be ideal as they germinate easily, cheap and easy to come by.
