1 Gallon rootball. I need advise from the experts....

Hello @dutdut ! People have the misconception that a big pot is always better and bigger pot means more yield. That's not true at least not always. I have managed to pull 250 grams from auto flower at 10 liter fiber pots while some other guy might have a 20 l and pull 100 grams. When you use smaller pots your first enemy is root bound but this will happen only if you are using plastic pots and not fiber. When roots grow and penetrate the fabric of the pot and have contact with dry air and light they die while in plastic pot that never happens and roots growing and twist around the pot. So the roots at fabric pots are self pruning. Also fabric pots give a huge air flow to your growing medium and your roots create many many root hairs ( root hairs are the part of the root that actually absorb nutrients while the root is just a channel to move them ) Your other enemy is that when growing in small pot roots take almost all of the space inside the pot and the soil can't absorb water. So you need to water very often or use an auto watering system and you also need to use more nutrients.Happy growing ! 👊
