New Grower Leaving soil outside before planting

[BillyWu]

Hi folks, random question. I've got a bag of Plagron Light mix sitting outside in my greenhouse. It's still sealed. I just want to know if anything bad can come of leaving it like that, like pH imbalances?

Some do have a shelf life. I know Premier Horticulture recommends that Pro Mix be used within 6 months of purchase. It should be fine but you might want to check with the manufacturer.

I would recommend that you bring it inside, or at least fill your pots and bring them in a couple days before you plant. MJ seeds like warmer soil temps to germinate, 75 - 80 degrees.

Right on, thought that may be the case. Cheers Muddy
