I will be using 3/4 gallon pots that are roughly 6.5in wide, and 7.5in tall. I will be thinking about the plastic saucers you can set your pots in. What do sea of green people use though? Wouldn't the saucers make it hard to squeeze in as many pots per square foot?
Well I always take the pots out of the growing space to water to help keep it a little more clean. So I can put the pot in a saucer, water it, then collect it and pour it in a cup so it's already to Ph it.
