I have 2 greenhouses.. One gets driect sun so after the first year i put up shade cloth.. With direct sun and temps up and above 35 degrees they were suffering.
In the other greenhouse which is more shaded naturally the plants grow slower and are not so vigourous as in the other greenhouse.
I would let them have some morning sun but not direct for a while.. I also only sprayed my young plants .. or let them dry out between waterings if using the saucer method.
When i grew my seeds i followed this guide,, ,was spot on with her advice. This was the result --- see photo.
I planted 100 seeds so not too bad.
