Hey everyone
I'm new to the forum and new to cactus. I've just purchased a few very ordinary beginners cacti to start with, a couple of mammillaria, an echinocactus grusonii (Golden Barrel), a weberbauerocereus johnsonii, an opuntia subulata montrose and a rats tail cactus. I hope to buy many more when I've gained a bit of experience. I've already done quite a bit of research and bought a few books but I'm astounded at the conflicting information out there, especially regarding suitable potting soil 'recipes' and how and when to water.
Anyway I have a few really stupid questions
I know that light is very important and my house is pretty dark during the winter so I've been putting them outside where they receive morning sun (when there is any LOL) and filtered sun during the afternoon and then bringing them in under cover at night. Is this a good idea or will I upset them by moving them around?
They are in small black plastic pots and I am thinking of repotting them into unglazed terracotta. When is the best time to do this? Also should I put crocks over the drainage holes or not, I always have done, but apparently it isn't such a good idea?
I have heard that the commercial (Debco etc.) cacti and succulent mixes aren't the best and someone recommended the potting mix from Collectors Corner in Braeside in Melbourne. Do you think this would be a good mix, it certainly looks a lot better than the Debco stuff which appears to be mostly bark? I've thought of making my own but there are just so many ideas out there and it's very confusing, coarse sand is good, coarse sand compacts, use coir, don't use coir, peat moss is good, peat moss becomes toxic to the plant, perlite is good, perlite floats to the surface and isn't worth using ...........etc. etc.

It does my head in
When should I start watering them, (it says no water or very little in winter) and how should I do it? A lot of books say to put the pot in a saucer containing water and leave it there for a few minutes, but others say to water from the top of the pot, which would you recommend?
I know these are very boring questions, but all the books and websites have different ideas and all I want is some basic information that will keep my cacti happy and healthy.
