Has anyone else found their plants in the greenhouse or polytunnel growing rather tall?  I could understand it if I was giving them the wrong feed and lots of nitrogen.  Some of the peppers are turning into 4 foot + (palm-like) trees and the chilli plants on shelving have reached the roof the greenhouse

Ah yes. It's our first year for growing peppers so I wasn't sure of the height of the plants. After what I thought was a poor start our two bullhorn pepper plants are easily over 3ft tall (and loaded with peppers fortunately). Pretty pleased with them so far to be honest

High light levels during the recent hot spell?

If they're producing as well it's all good news.

some of my sweet bullhorn are at the top of my greenhouse and the roof is like 7 foot and they still haven't set a fruit.

I don't know what to do with them now to be honest wether to nip the tops and hope for side shoots lower down.

Am sure that there are others on here more experienced with greenhouse culture, but:

1.  I would stop the plants by nipping out.

2. Ease off on watering, to initiate flowering.

Best wishes
