is there a reason why shrooms would grow from the bottom edge of the cakes?

the first boomers came and they seem to be more prevalent around the bottom lips of the jar cakes... i know my conditions arent right to begin with because this is a i d g a fuck show me what a boomer is grow, but any reason why this might be?

Probably more moisture around the bottom. Do you mist?

How well do you light block the sides and bottom?
Pins are typically (but not always) triggered by light.

yes it might be collecting because its sitting on plastic sheet sqrs on perlite.

the light is coming from the bud so on the side but the pins are on the far sides from the light???

Higher humidity and moisture toward the bottom of the cake.

It's common for boomers to grow from the bottom of the cake. That's fine, as stated it's from the extra moisture there etc. and they work just as well as the ones on top of the cakes.

Did you double-end case? That's putting moist vermiculite both under and on top of the birthed cakes. It helps a lot. Just keep the top well misted.

You can add the extra verm layer any time. If there are already pins/shrooms on the top you can wait until the first flush is done.
