Plants 3 years old, grown from seeds.
Soil: peat, perlite, quartz sand 40/40/20, transplanted in May, Ph 5.5.
Sun 4-6 hours. Humidity I don't know, I think it's low.
I don't see any insects, except for a few Sciarids (midges), they have never interfered before.
I water the plants once a week. I check the moisture of the soil with a "moisture meter".
