You would think bulk wouuld be the way to go but......... There is 27 cubic feet in a yard. a 2 cf bag of pine fines from walmart is $2.65 a bag so $35.75 a yard. A yard of pine fines from the only spot that sells it is $30. Walmart is 5 miles from my house..the nursery that sells the pine fines is 30 miles. In my case the bulk is more expensive. I don't grow my BB in pots, I grow in the ground. The pots were for a friend that wanted an easier way to grow the blueberries.

Another soldering iron user here! I vary on the number of holes I put in, but I usually put at least one, sometimes two, holes in each quadrant on the bottom, and four in that little trench (two in the bottom and one higher up at each end of the trench). I also put one hole on each side near the bottom. These side holes can help if the bottom gets clogged/frozen/blocked, etc. So usually at least 12 holes total, sometimes 16. Honestly, I can't give a good explanation of why sometimes I do 12, sometimes more. It's just how the mood strikes me the day I'm poking the holes, lol. By the way, I also use my soldering iron to poke a hole up on one side of the jug, at the bottom of the handle. This hole I use to poke my scissors in to start cutting around the jug. Not a ridiculous question at all! Experiment and you'll find what works best for you. Remember, it's easier later on to add more holes than try to tape up the extras! (too many holes can lead to too-dry containers). Good luck and have fun! Dee

You know, mine doesn't look like all that much. People would never, ever guess the variety I have out there, though, well over 70 different kinds of plants! Everything I did was on a much smaller scale than the average winter sower would do. I have a couple of lasagna pans with 13 different kinds of flowers in each, and then some kitty litter pans with 12 types in each. I guess normally that would be about 50 jugs? I also have quite a few water bottles and a dozen or so jugs. The gallon size jugs have at least four varieties in each. Most of it fits in my 3x5 cold frame.

I just searched for and found a response I had posted awhile ago on "how many jugs per bale of pro - mix". Promix is compressed so to be safe you might want to say a bale = 4 cu ft (below is copied/pasted from an old post) In case this is helpful to anyone.... I have been keeping track and on one 3.8 cu. ft bale of pro-mix I have filled 121 containers. Moving on to my second bale now. What I filled: About 50% gallon milk jugs and the other 50% larger capacity plastic boxes (salad, spinach, cookies and baked goods) I'd say an average of 3" - 4" soil depth, but more towards 3". Sooo, if I am doing the math right (don't count on it!!) you should get about 60 containers from each of your 2cu ft bags. Does that make sense? Nancy Nancy
