USB water bottle humidifier

[legalcanada]

Does anyone have any experience with these? My grow tent is only about 35%-40% humidity and am just waiting for my beans to pop now for 1st grow... They humidify roughly 40ml/h, do you think that is sufficient to raise my humidity levels a bit? I think it'll go up a bit anyways once i have plants in pots and am watering them anyways tho but for 10$ it seems worth it. Thanks!

i doubt that would make much of a difference, especially if you have an exhaust fan in your tent
