I would envy a greenhouse 1,000 times smaller than yours!
>> Then we pot them up in either 50 cell trays or 3.5 liners
What is a liner? I found examples of what look like gallon-size or at least quart-size shallow pots made of coir. Is it like a coir pot designed to slip inside some other pot?
Another site made them sound like the small plants themselves, with well-established small rootballs, but not yet root-bound.

I thought those were called "plugs", tiny rootballs taller than they are wide, ready to be "plugged into" a bigger containers.
Or is a "plug" a very small "liner"?
