Electricity prices are higher than ever, meaning each month a grower has to look forward to another sky-high bill. Getting as much flower from your indoor grow room is essential during an economic crisis, so in this article we explain the various ways to grow large yields, as well as our top tips.

Intense Lighting 

How intense and how much P.A.R your indoor grow lights produce per square foot, plays an enormous role in how quickly the plants grow, and how they will perform during the flowering cycle. When it comes to growing Cannabis, HPS and MH should start at 600w up to 1000w for the most effective results. Avoid using units that are lower than 600w unless being used for mother plants or the vegetative stage. L.E.D grow lights are incredibly efficient, meaning that some high performance lights only require 250w of power. 

Top Tip: You can invest in a P.A.R meter that will allow you to maintain the optimum level. Avoid cheap LED lights and always do your homework and research. 

Big Yielding Genetics

You will only get so far with low yielding cultivars, and if you really want to hit the jackpot in terms of yields, then starting with large yielding genetics is very advantageous. Typically, plants that are well known to produce commercial scale yields are often hybrids that are made up of indica and sativa genetics. These will be the best candidates for plant training, which further increase the canopy and overall harvest weight, and the flowering time can range from 9-10 weeks. 

Top Tip: Do your research before buying the genetics and see which are known for putting out pounds. Different seed banks will be able to advise you on which are the most productive.

Plant Training

There are a number of different training methods that can help increase yields. When these techniques are performed at the right time, on the right strains, then the results can be impressive. Plant training covers topping, fimming, pruning, tying down and snapping stems in some cases. When combined with a large yielding strain, plant training can be performed until the first week of flowering, before it becomes counterproductive and may even induce stress.

Top Tip: Take the time during 18/6 to get all the necessary training out of the way, before the plants are flowered under 12/12.

Switch To Hydroponic

A way of growing Cannabis that does not use soil and allows plants to be fed with chemical nutrients, specifically designed for hydroponics. The growing medium will be inert, ranging from rock wool, coco, hydroton or perlite. Compared to organics, hydroponics is much more complex and requires much more maintenance than soil. It is much easier for things to go wrong, however the yields that can be expected will be far greater than an organic grown plant. 

Top Tip: There are many different systems and styles of growing. Dripper systems are the most common and basic, requiring only a pump and dripper lines.

Nutrients and Boosters

The nutrients that you feed your plants will determine how well they can stack on weight. Of course, there is a balance between how much food they should have based on the light intensity and maturity of the plants. Most indoor growers can often go overboard when it comes to nutrients and watering. Using boosters during week 3 until week 6 can be a great way to increase yields and allow buds to really fatten up and swell with a dense appearance. 

Top Tip: Flushing your plants of all nutrients and built up salts, will produce the best tasting flower possible. This refers to feeding only water for the final 14 days.

Supporting Plants

Once your indoor or outdoor plants start packing on the size and weight from week 4 onwards, it can be a good idea to provide extra support. By doing so, this allows the plants to focus on only producing buds, and eliminates the concern of drooping branches. Using bamboo canes, and placing them around the outer part of the pots, is the easiest way to tie the side branches up. Heavy side branches that begin to topple over are at risk of becoming infected with mold, and should be supported up right immediately.

Top Tip: Adding a support system early into the flowering stage can be beneficial, and save time later on.

Sea of Green Growing

SOG is a style of growing that uses a high volume of plants that are grown in 7.5 liter pots with a short vegetative time. The outcome is a medium-sized canopy of buds that can fill a grow tent or room. The benefits of Sea of Green, is that all the grow space has been efficiently used, and the room can be rotated every 8-10 weeks depending on the strain. SOG is an excellent way to reduce electricity bills and significantly reduce the vegetative time down to a 2-week period.

Top Tip: Not all strains work well in a SOG, so research which ones are the best. Typically, indica dominant and OG Kush strains are ideal. 

Coco Grow Medium

Coco coir is basically the hair from the coconut husk, and has been washed and treated with salts. Paired with hydroponic nutrients specifically designed for coco, growers can be rewarded with big yields of top quality tasting flowers. If you have not grown with coco before, then give it a try, as you may find it to be the perfect substrate between soil and hydro. 

Top Tip: Coco coir is very soft and pleasant to work with, and will encourage the most prolific root zone when cloning Cannabis. 


If you are able to apply all of the above together, then you should be well on your way to hitting record-breaking harvests. For most home growers, keeping their curing jars full is their main priority, so we hope that this article will help get you through the tough times ahead!
