I bought a set of 7 gallon bags to plant peppers and basil in my apartment patio in October 2018. The handles on the bags are the best thing for a petite person like me. It makes it very easy for me to move the bags without snapping my stick like wrists, neck or back. The bags are holding up great still and they did see all the weathers. I am in Arizona and October can be pretty drying for small containers. I had to water the plants every day in October. The soil would get really dry and the fabric of the bags is very porous. If the soil is not packed completely along the walls of the bag, the water leaks out from the sides when watering. Also the water drains out quickly when bag is watered at once. As a solution to this, I water half the amount needed in the center of the bag and let the soil absorb the water, then I water the rest half amount. I would suggest not putting the bags in wet areas because it does have some fabric mixed in and it will eventually wilt/decompose.

The pepper plants had the misfortune of snapping during a storm. They never really got healthy. Despite that one of the pepper plants now has 5 baby cubanelle peppers. The basil grew very well in these and I have already made basil pesto 4 times.

I think for a beginner gardener with no access to a backyard, this is a great set of quality containers!

I bought this set of fabric bags to use for growing peppers. They worked great and were so easy to fill, plant, and even move once filled. I had a bumper crop of peppers and look forward to next season!

Dec 2017 Update:
So far I think fabric grow bags is my favorite style of container gardening, compared to other styles like regular pots, 5-gallon buckets, container hydroponic, and wicking containers (City Pickers/Earthbox). First, grow bags are pretty durable while being relatively cheap, so you don't have to shell out lots of money for other high quality containers. I can't speak for much larger sizes, but 7 gallons and under has been a good experience for me. Second, drainage and aeration allows the plant roots to grow well and it seems to me to help reduce diseases. I now use 50/50 compost and potting mix (the kind with fine pine barks and drains well such as by Ecoscraps or Just Natural, not the water retentive and acidic peat moss kind).

Only downside is grow bags have no wheels so if you like the convenience of pushing them around, you might have to invest in some expensive 'plant dolly', carts, or build your own.

I bought the 1, 2, 3 and 5 gallon ones. The sizes calculation are a bit of a stretch. If you fill the soil all the way to the top then they'll pass, but just expect slightly less than the actual size. It's a good price and looks like good quality so I have no complains.

For my hot climate it dried it very fast and needs watering every day, because of this I add more compost in them along with the potting mix, or double stacking the bags to reduce drainage. (Some people are against compost in containers, but imo this is less of a problem in grow bags because they drain so fast in hot climate).

The roots grow really well in them. I use 1 - 2 gallon containers to grow microdwarf, 3 gallons for determined dwarf tomatoes, and 5 gallons for indetermined dwarfs, cherry tomatoes or full sized tomatoes but top them off and limit the plant to one or two stem.

At first I wasn't sold on these, but we needed something to use outside for tomatoes, pumpkin, and watermelons, so I got these. Filling with good soil, these are fantastic! The plants are thriving, and with these being fabric, over-watering is much harder to do. These also work great for plans that like a well-drained soli, like the tomatoes.
Even filled with dirt (two or three cubic feet), they are not so heave that they cannot be moved. They have held up well, and have proven to be a great addition to our garden.
