That’s the thing about cO2. It’s basically like an octane booster for a higher performance engine. You won’t really find it useful unless your grow is dialed in and you have enough light to make use of it. And at that point.. there’s only one really easy and reliable way to get it in there and that’s with a tank and regulator and a monitor. I hated hearing it too and realized I would just need to bite the bullet at some point. Buy once cry once. If u want co2 get a tank.
