Hi again! :)
I've read that it's a good idea to keep the bottom of the seed trays warm. How does one do that? I imagine some kind of reptile heater - but what kind and where do I get them from. Is it expensive to warm a lot of seed trays?
Also - how long should the heat be left on for? - all night/all day. For how many weeks - the whole time they're inside or just until they're a certain size?
Thanks so much!!
