I'm about to repot all my indoor plants after a good six months of growth, and with colder weather coming in Ontario, I'm looking for some solid soil options. I've previously used Miracle Grow, but I've read it might contribute to fungus gnats, which I have a big problem with. I'm considering switching to peat moss because I like how well it drains. Any other suggestions or additives I should consider? Thanks in advance!

If you're into coco coir, that's a solid choice! Adding perlite is also essential for good aeration. For tropical plants, consider including coco chunks or orchid bark for extra goodness! 😎
I recommend using Promix, and trust me, it's way better than Miracle Grow. To combat gnats, keep a quarter of a mosquito dunk in a gallon jug of water, and use that to water your plants. This has been effective for me with Promix, unlike the gnat problem I had with Miracle Grow.
Honestly, fungus gnats can pop up in any organic mix. I've had good luck using BTI drops: just a couple drops per gallon of water helps kill the larvae. I use MICROBE-LIFT BMC2 for that.
I'm in Ontario too and I sometimes use Miracle Grow, but I've started baking the soil at 180°F. It helps with pests, just be careful to air out your place afterward because it can smell. I also use boiling water to treat it before storing it in an airtight container.
I've been using a mix of coco coir, compost, and perlite for my plants. I chose coco over peat for sustainability, and I've found that I really enjoy using it!

Interesting! Coco coir is definitely a great eco-friendly option. I guess it holds moisture well without being too waterlogged.
