Have you tried making newspaper pots? I watched several videos on Youtube that I just found too complicated, but I found another that was right down my line. I love Patty Moreno, The Garden Girl. She has great tips on vertical gardening, making raised bed etc. She also had a great video on how to make newspaper pots. I've modified a little, but here it goes:
In the above picture, I'm using a 1/4 sheet of newspaper folded in half. You will want to fold it across not length wise. Next, I used a pint size canning jar, leaving about a 1/4 of the mouth of the jar out of the newspaper and roll the jar until all of the newspaper is used. Using biodegradable tape, tape the ends of the newspaper together. If you don't have biodegradable tape, you can remove it from the newspaper later and toss the newspaper in the compost bin, which is what I plan to do. I actually used scotch tape, but duct tape will work too.
Turn the jar upside down on the opening of the jar. Fold the bottom of the newspaper as if you're wrapping Christmas gift. Tape the folds down.
Remove the jar from the newspaper, and you have a great newspaper pot. You can adjust the opening of the pot to the height you would like by just folding the top inward. Fill with seed starter or potting soil and you're ready to go. The newspaper will absorb water just like a peat pot. I used the newspaper pots to try to start my sunflower seeds. So far, so good.
