My greenhouse are not too big either. The picture are from last year:
Last year I manage to have a rather large number of plants in it. I think this was May last year:
And this is the greenhouse in June/July:
This year I know the greenhouse will contain the same number of plants or more. But all the lily seedlings will be growing at the tables and save allot of space to the lilies that I'm going to pollinate.
This is the size of the new boxes I am going to grow the seedlings in. The few seedlings I grew in these boxes last year on the tables was large. This winter I have got 20 of them. It is possible to grow 50 seedlings in each box and maybe 12 boxes on each table.
