Enola KnezevicThey say succulents become leggy if they do not get enough sunlight. But, mine turn leggy on the south facing window. And I even had some turn leggy on a west facing balcony (back when I had a balcony). So, how on Earth could I give them more sunlight?

@AncTreat5358 Not officially, it's a rental but a very old house. Normal glass does block most of UVB but not UVA. Guess I should get one of those triple sensors: soil humidity, pH, light 🤷
@rhelune Ah, I didn't realize that property of normal glass; I thought coatings were required.
Hopefully one of the triple sensors you mentioned might enlighten you on the needs of the plants.
Sorry I wasn't of more help!
@AncTreat5358 You did mention something important, thanks!
