12 Tips for Getting Killer Yields

You wanted to grow at home, you wanted to grow safely. You got yourself a BCNL grow box as an easy way to grow, while ensuring you wouldn’t be lowering your property values.

Grow boxes allow you to grow 24/7/365 and makes it possible to get decent yields every 8-12 weeks. But what if you want more? Is that possible? It sure is! These tips can help increase your yield by up to 50%.

1. Optimal Conditions

If you want your plants to thrive, then you need to ensure the optimal conditions are present to ensure the plant can perform to its full potential.

Monitoring your pH, TDS, temperature and humidity are all important to ensuring your plants thrive. You’ll need to make sure you’re able to keep all your levels within optimal ranges, and that you’re keeping up on things like pruning dead or non-performing branches to allow the plant to put its efforts into other areas.

2. Your Strain

Each strain is unique, and different strains have different properties that make them behave in different ways in different conditions. There are strains that are known to yield low, or that are known to grow better outdoor in soil.

It’s important that you do some research into the strain you’re looking to grow, ensuring you select something that actually has a chance at performing well for you, even if you don’t do everything perfectly.

A few things to consider when looking at a strain:

  • Is it high yielding?
  • What’s the average time from seed to crop?
  • Does the strain handle stress well?
  • Does this strain grow better outdoors?

3. Shock Ripening

Having a plant move from vegetative state to flowering requires changes in the lighting and watering cycles. Back in 2010, High Times published an article from a BC grower called Medicine Man about a method he called Shock Ripening.

After flushing in the flowering phase, you can do a Shock Ripening by giving your plants 3-5 days of pitch black, along with ice water in your reservoir. This technique shocks the plant into pushing growth to the buds and will enhance not just your yield, but aroma and potency as well.

4. Shock Pruning

While regular pruning will help keep your plants tidy and getting the best light exposure, by performing shock pruning at 2 weeks of flowering, you’ll see an increase in your yield and quality of buds.

You’ll simply strip off the lower leaves and branches, leaving just the top 4 nodes of the plant. This will force the plant to focus all it’s energy where the light is. It will also increase air flow in your box while decreasing your chances of both pests and mold!

5. Shock Flowering

When you switch to flowering, it’s very common to set your lights to 12hrs on and 12hrs off initially. Many people have had success with shock flowering their plants for bigger yields and buds.

Instead of the 12/12 timing, you would give your plants 24-36 hours of complete darkness to initiate the flowering. This will allow more energy to be put into the flowers, resulting in dank buds.

6. Calibrate Your Meters

You should be calibrating your meters regularly to ensure they are providing accurate readings. If your readings are off, you could be over or under feeding your plants in terms of nutrients and pH.

Needless to say, proper feeding schedules and amounts will ensure your plants grow strong and healthy.

7. Nutrients

When plants are out in nature, they get their nutrients from the soil that it’s grown in, but that doesn’t mean it’s getting the best dose to perform their best. Whether you are growing with hydroponics or soil, you can seriously up your yield and quality with proper nutrients and boosters at the correct times.

It’s good to note that you should stay away from brands with high Phosphorous (P) as it can negatively affect your yield and stress out your plants.

8. Crimping and Bending

Without getting too deep into it, plants use an internal network of cellulose that carries water and nutrients. By gently twisting and bending your branches twice a day during the vegetation phase, you break some of the internal structure that then rebuilds itself thicker and sturdier.

This basically activates the plants immune system and allows for more notes and water to travel to key growth areas while also protecting itself more from stress and other environmental factors.

9. Foliar Feeding

Plants also absorb nutrients through their leaves, so by lightly spraying your leaves with a nutrient solution. Plants have been shown to absorb as much as 95% of nutrients this way!

This allows you to hit the plants with an additional burst of nutrients at key times throughout your growing cycles.

10. Be Prepared

There’s an old Ben Franklin axiom stating that “an ounce of prevention is worth a pound of cure” and it’s just as true now as it was when it left his lips. Make sure that you’re preparing your clones or next round of plants ahead of time.

This will result in much less downtime and a more productive space. This additional time and effort can result in additional crops every year.

11. SOG or SCROG

If you’ve never looked into SOG (Sea of Green) or SCROG (Screen of Green) methods, take a look at our intro article here. Without getting into the nitty gritty, both methods can reduce your time to harvest and increase the yield of your plants.

The main reason these methods work is more even lighting across the canopy while packing more plants into the same space.

12. C02

Plants LOVE C02, it’s what they breathe! Giving your plants a steady supply of C02, you’re literally giving them life, it’s like an oxygen bar for your weed plants.

This tactic has been known to increase yields by 25-50% depending on strain and other environmental considerations.


As you can see, there’s a whole range of different options for increasing the yield of your plants. If you’re looking for some guidance or have questions, feel free to contact our discreet Grow Advisors.
