Northern Lights Seeds

What pH is Suitable for Northern Lights?

Look, if you're growing Northern Lights — this old-school, knockout indica that’s been around since your uncle’s first lava lamp—you’ve gotta get the pH right. Not perfect. Just right. There’s a difference.

So what’s the sweet spot? 6.0 to 6.5 if you’re in soil. Hydro? Drop it a bit—5.5 to 6.1-ish. Don’t overthink it. But don’t ignore it either. This isn’t some throw-it-in-a-pot-and-hope-for-the-best strain. It’s chill, but it’s not lazy.

I’ve seen people wreck entire grows because they didn’t check their pH. Like, plants yellowing, curling, looking like they’ve seen a ghost. And they’re sitting there wondering if it’s a nutrient deficiency. Nah, bro. Your roots are locked out because your pH is whack. You could be feeding them filet mignon and they wouldn’t absorb a damn thing.

And don’t trust your tap water. Seriously. It lies. Get a meter. Or at least those cheap-ass test drops. Something. Guessing is for blackjack tables and Tinder bios—not cannabis cultivation.

Now, Northern Lights is forgiving. That’s part of why it’s a legend. Mess up a little? She’ll still push through. But if you dial it in—get that pH humming right in the zone—you’ll see what she can really do. Dense, frosty buds. That deep, earthy-sweet smell that hits you like a memory. The kind of smoke that melts your spine and makes you forget what day it is.

Oh, and don’t chase perfection. That’s a trap. Just aim for stable. Consistent. If your runoff’s coming out at 6.3, don’t panic. If it’s 5.4? Yeah, fix that. But don’t get neurotic. This plant’s been around longer than most of us have been alive. She knows how to survive. Just don’t get in her way.

Anyway. Keep it between 6 and 6.5 in soil. A little lower in hydro. Don’t be a dumbass and ignore your water. And if your leaves start looking funky? Check the pH before you dump a bunch of Cal-Mag in the pot. Trust me.
