Why/how do you guys water only every couple days?

U can look at it two ways, the person that water every few days will tell u your pot is tooo small. The person thats waters everyday says your good. I water 3/4 times a week

It’s all about environment coupled with your pot size for the most part. I would be going more for 5 gallon for autos if you don’t wanna be watering so often. Side note - Keep in mind, if you are having that quick of a dry out - you could be getting salt build up within the medium. Keep an eye on that and monitor run off. That was something I overlooked for a few grows and caused lock outs and nutrient issues. If you’re drying out quickly, lower your strength of feeds and make sure there’s appropriate run off. Salt build ups will lock nutes out and throw off pH and your plants will suffer. Just something i wish I would have realized earlier on. But if you’re not getting run off with feeds, sometimes you think the medium is fully saturated when in fact it is not.. Anyways, I digress - good luck!
