Trash bags for pots?

I have some contractor trash bags that are a thick plastic and should block out any light, so if I put some slits or holes in the bottom can I use them for pots. I am going to do 10 monster trees outside but I want them to get as big as possible so I want larger than a 5 gallon bucket.

YOU WONT GET ANY AERATION IN there using plastic and it can trap some heat which isnt good for roots.

if your gonna take the plastic route id recommend

so cheap its not a cost.
warning: plastic pots are kinda whorish when its watering time.
these come pre holed and stand up nicely.

I was watching a show on weed that's on netflix and the growers had the outdoor plants in big black bags full of soil if I cut the entire bottom off and let the bottom of the good soil touch the ground would that help at all or is that just a dumb idea lol.

if you could put some sort of raised mesh then placed the rootballs on that, yes.
just dirt, no.

I might just have to dig some big ass holes in the ground again time to get a new shovel...
