I guess you could. I wouldn't recommend it. There would be limited water flow to the main root area, therefore limited O2 getting to the roots. Just seems like a recipe for disaster. Net pots start at like $.16. If you don't have that to spend on your plants then idk what to tell you.. this isn't a cheap hobby to start up but it pays off.what about using standard pots for DWC, do you really need all those holes?
