3 gallon pots????

new at this i am growing spicey white devil in 3gal pots and thay are about 20in tall
when do i have to go to a bigger pot and what size do i need ? and one more thing should i have to water them at leased ones a weekdose any way some of you masters can help a new guy???

i would go to at least #5's or 7's when they are rootbound. If you use an airier mix containing more perlite or coco or whatever you use, you will need to water more often. I would say you should shoot for your soil to dry completely within 3 days. I feel like this gives you less of a chance of over watering, and more opportunities to feed at the same time. Make SURE that the soil is dry when you dig a couple inches down, before watering. It is also important to properly water you containers. You want to completely drench the entire container of soil when watering, so make sure there is a fair amount of runoff. This ensures that you are taking full advantage of your container space. Otherwise there wouldnt be any reason for those bigger pots.

thank you i need all the help i can get

everyone starts somewhere mi amigo
