this wont hold 16 trees. you just want small to med plants right? if you want big plants just buy a third or fourth container.
when i started out, which was not that long ago. i had put only 4 plants in a 14 gallon rubbermaid tub. the same one that the cloner is built out of.

them i vegged for 6 weeks and they outgrew the tube quick. if you went 12/12 from seed or vegged 1 or maximum 2 weeks, you might be ok with 4 plants. just my opinion. again when i came to these problems in my grow a adapted fairly quickly. when i outgrew the tub, i went to the 5 gallon buckets set up.
these are the same plants. out of four 2 where females. newbie mistake #113. should have sexed them before i put 6 weeks of money, time, and care into the plant to end up male.
1982grower do you run that many plants in one tub. i guess you have to keep in mind that i have always been aero/DWC. ever since the cloner, i have had a water pump and spray assembly in the reservoir nr every set up. IMO the overall development of the plant is faster and more efficient.
