Is the humidity a thing?

it's super important... in fact nothing is more important to a plant than the environment.... what's the environment : light, humidity, air flow, temperature that sort of thing. Humidity together with temperature are the only things that really determine growth rate, through something called VPD . Get your VPD right and you can have optimal growth, something like twice as quick as not optimal VPD. Check it out here : https://pulsegrow.com/blogs/learn/vpd. Hope this helps , anything else you need just let me know 🚀
