what size to re-pot and next soil?

Ms. Jitomate · February 11, 2013

I currently have 144 small tomato plants with 4 true leaves in 3" by 3" plastic grow bags in approximately 3" to 4" of starting medium. The plants are 2.5 to 3.5 inches right now and are 5 weeks old. I need to transplant them because I am donating them for a plant sale for my daughter's school. One gallon pots seem too expensive because of the amount of soil needed. What would be a better size? And what would be the least expensive potting soil for this next transplant into these pots? I was thinking Euro pots 17 cm with 6 5/8" diameter and 6" tall sold at the greenhousemegastore.com, so that they can sell them for $4 to $5 each. Capacity is 2.588 qt. but is that filled to the top? These are seeds purchased from Heritage Tomato Seeds and Wild Boar Farms.
