On this same topic: we have no trouble _starting_ seeds. But, after
we transplant them, some/all the plants develop a 'skinny neck'
condition where the stalk enters the ground.

The brocolli has been particularly bad. We used 2" round peat pots.
Planted in some 'starter mix', in a tray with a clear cover, watered
from the bottom. 2 shop light about 8" above the trays. After
germination, we removed the cover. Transplanted after ~6 wks. We
removed them from the peat pots when we transplanted them.

The brocolli grew a reasonable-looking stalk, except that it got very
scrawny near the ground - it couldn't support the plant.

And then a woodchuck ate them all.

If anyone has any thoughts about the scrawny neck, I'd appreciate
hearing them.

Thanks,
George
