I found potato fabric grow bags with a window showing the roots at the bottom so you can see if the soil is dry or wet. You can also keep an eye on the root growth.
i am using them for potatoes. i didnt like the ones i had for weed they had plastic lining even with the holes in the bottom i wont use them. fabric pots are more forgiving for me if i overwater
Roots don’t like light so the window is not a good thing for MJ. Cloth pots are the best for soil / soiless mediums.
I knew that. But thanks for reminding me
