Hello. I'm a little confused about the temperature requirements of pygmy drosera. I've read that they usually grow during winter, but I've also heard that they can do 20-25C year round. If I was to sow gemmae and seeds, would it be best for me to plant them in typical 20-25C temperatures, or can I put them with my highland terrarium that ranges 12-22C?
Also, would plastic drinking bottles make good pots? I've read that they like them tall, but the bottles aren't made to be planted in, so I don't how they will do long term. I was thinking normal 500ml bottles, but they look kinda narrow.
