What to Consider When Buying Weed Seeds in Chicago
When you're aiming to buy marijuana seeds in Chicago, it's not just about the legality – you need to think about the local weather too. Some strains handle the crazy weather and big temperature swings far better than others. The best bet is to go for strains that flower quickly and can tough it out against mold, cold, and humidity. Now, let’s dive into more details.
Climate in Chicago
Chicago has a continental climate, which means hot summers and chilly winters. Summers can be humid, while temperatures in late fall drop quickly. It’s best to kick off outdoor planting in spring so that your plants have time to get strong. By the end of September, nighttime temps can drop to about 54°F (12°C), so make sure to harvest before then.
High humidity toward the end of the season can lead to mold, so it’s smart to pick varieties that can handle fungal issues. And don’t forget about those strong winds that can mess with your plants. The way to go is with autoflowers, fast-flowering strains, and those that can deal with humidity and sudden temperature swings. In the next section, we’ll share our top picks for Chicago.
