pH Basics – The Silent Key to Strong Cannabis

When growers talk nutrients, lights, or genetics, they sometimes skip the most important player in the grow: pH.

So, what is pH?
It’s the measure of how acidic or alkaline your water and soil are. And here’s the kicker: if your pH is off, your plants can’t eat.

That’s right—even if you’re giving them the best nutrients on the market, a wrong pH locks it all out. Hungry plants in a buffet line with no plate.

✅ Ideal Cannabis pH Range

• Soil: 6.0–7.0
• Hydro/Coco: 5.5–6.5

Stay in this sweet spot, and your plant absorbs everything it needs. Slip out of range, and you’re asking for trouble.
