Thanks for the reply mate.
I use a spray thingy (like how they have at the barbers) and spray the soil with water once every 3 days. Just twice per pot. It wont be wet. But just appear moist.
I bought these three in particular because they clean the indoor air apparently according to NASA Clean Air Study
My wife wants to grow some Garlic, Ginger, Tomato, Chilli, Basil, Parsley and lemon grass.
But I heard that they attract insects and pests. And I am, in my rented apartment, skeptical to grow them indoors as we dont have a balcony or a terrace.
I will definitely visit this thread and go through it from the start as I find some tips and DIYs very helpful.
Also,
The draceana will need more water than that. I just pour water in, until some of it comes out at the bottom. If the water is still there the next day, pour it away and don't let the plant sit in it, or the roots might rot. The aloa and the snake plant, can't see them to be fickle. They come from an environment where they get soaked for a bit and then sit dry for a bit, there isn't too much you can do wrong.
Of the plants your wife wants - the herbs will live in a pot on the windowsill, no problem. You can actually just buy them in a pot in the veg aisle of tescos or similar.
You can grow chilies inside, they might need fertiliser or good earth/repotting every year to have fruits though. Tomatos you could grow inside, but to actually get decent amounts of tomatoes you'll need big plants and quite a bit of space. They need a lot of water too. Ginger and garlic are roots, they might be more difficult to grow indoors. Garlic also smells! Maybe a box outside the window is better?
