Broccoli Growing

Question

Everytime I start broccoli after a few weeks are past the stems get long and, as thay say, leggy. Why is it that greenhouses have plants with nice straight thick stems? What’s the trick to preventing this?

Answer 1

The light is not bright enough for them. They need more light. Try setting a fluorescent bulb just a few inches above the seedlings and that should correct the issue.
