How Do I Read BC Northern Lights Nutrient Charts?

We really want you to grow great yields. That’s why we've developed a comprehensive nutrient guide that breaks down the exact measurements and exact times to keep your plants looking their best.


To start, there are two growing stages: vegging and flowering. Vegging is when your plants grow their beautiful, luscious roots. But more importantly, it's growing the structure of the plants. As long as the lights are on for 18 hours a day, and off for 6, the plants will simply keep growing branches, leaves, and roots.

When your plants reach 8-10 inches in height, that's when you switch your machine over to flowering. Your lights are on for 12 hours, off for 12 hours. Flowering is when your buds form.

Our charts are separated into these two stages. With each stage, start from the top, and work down adding the nutrients that came in your package. As an example, let's take a look at the first BloomBox veg chart that comes with the BloomBox grow manual.

*Veg Boom and Prop-O-Gator included in Gold nutrients package only.

So, for example, if you're using Common nutrients, for week 1 you’d be adding 11.5 mL of Common into your nutrient tub, mixing it with the water, and feeding it into the basin for your roots. PPM levels are also included to give you an idea of how much nutrients you should have in your water if you were to measure your water with the PPM tester.

Weeks 2, 3, and 4 are also clearly laid out to show you how much nutrients you should be adding.

The difference in the types of nutrients you use is really based on what you decided to commit to. For example, BCNL's Gold package also offers Veg Bloom Plus and Prop-O-Gator – just a few more nutrients for you to play with to get a great grow.


The flowering section might be a little more confusing for some. See below:

This may be due to the fact that you have your base flower nutrients, and any add-ons like the Silver Additives or the Gold Additives (see below).

Similar to the charts above, the PPM levels are included simply to show you how much nutrients you have in your water. With the Silver and Gold nutrients, you just add whatever that week tells you to, and that exact amount. Remember: the numbers across the top (from 1 to 8) is the week your grow's in.
