Gardzen10-Pack 20 Gallon Grow Bags, Aeration Fabric Pots with Handles

Q: Can you grow butternut squash in these? Is there no room for them to grow out their roots? My garden soil is super dry and hard full of rocks.

I would say no because butternut squash have a very deep rooting system; It's 18" minimum. These aren't even 18" tall. My advice would be to borrow a sewing machine and go to the thrift store. Buy men's long jeans and cut off the legs and split the seam on the inside. Sew them together to make 1 wider "tube." While inside out , tie a knot on one end for a bottom and flip right side in. Now you have an extra tall make-shift grow bag. I've done this for various reasons in the past.

Q: What size should I buy to plant vegetables- squash, tomatoes, eggplant, peas, cucumbers?

I use 25-30 gallon pots for my tomatoes( the bigger pot the better the results and less watering) and go a little smaller for squash, eggplant and cukes. Patio type eggplant and tomatoes can go in even smaller pots. I have some of my snap peas in 5 and 7 gallon containers and they are doing well but the ones in a 15 gallon pot are huge. They are even much bigger than they’re supposed to be.

Q: Could these also be used indoors?

These are mainly designed for outdoor usage which provides fast drainage and better aeration for the root system. They can be used indoors, if that is what your intentions are. Keep in mind, that when using these types of pots, watering schedule will change. Use a moisture meter to maintain the level dampness your plants need.
