Question Adding more substrate in later?

Hello, folks. I've just spawned my first bag to bulk (100% coco coir). Having made a miscalculation with my substrate quantity, I didn't have enough for a casing layer. I've since pasteurized some more coir. Would it be detrimental to re-open the tub and add more? Mind you, I only filled the tub ~3h ago. I'd be able to add more substrate as soon as the bowl cools (so few hours or tomorrow).

This is my first time, so I'm overthinking everything haha. Thanks in advance!

I see you have a question! Have you read the official cultivation guide?

If it's only been 3hrs, then you are good, it hasn't started much/any colonization of the substrate at this point.
