How to Yield a Large Harvest From a Grow Room

 

Whether you’re growing cannabis for commercial or personal use, maximizing yield is key to a successful crop. Commercial cultivators are often happy to share tips and tricks of the trade. In this guide, you’ll learn which rules to follow to get the most out of your grow room.

Choose Plants With Good Genes

The best crops start with the best genetics. When buying from a reputable seed bank like i49.net, you’re guaranteed to get phenotypes that work well for the size of your grow room and the equipment being used.

Keep the Room Comfortable for Your Plants and Their Genes

A crucial component of a successful indoor grow is good air circulation. Proper airflow allows growers to precisely maintain the environment. Because cold air sinks and heated air inevitably rises, though, it’s important to choose easy to grow marijuana seeds with the right genetics for the indoor growing environment.

If you’re growing a heat-tolerant strain, like super silver haze or super lemon haze consider putting those plants near the top of the grow room. However, strains that are prone to coloring at cooler temperatures should stay near the bottom. Because the lower part of the room will naturally be colder than the upper part, growers can adjust temperatures for cold-weather strains.

With a vertically oriented grow room, it’s easier to put strains needing less attention on top while leaving the bottom levels for plants that need more care. That way, each plant gets the love and care it needs, regardless of its strain.

Group Strains According to Their Requirements

In large-scale indoor grow ops, cultivators often grow several strains. They typically find the most success when they grow strains that prefer similar environments and finish at about the same time. With this strategy, it becomes easier to maintain a consistent indoor environment.

Grow the Right Number of Cannabis Plants

Though it’s not an exact science, the number of pot plants will affect the overall yield in a couple of ways.

  • When growing more plants, it’s easy to fill the space faster and harvest more crops per year if all other factors remain constant. When harvesting more often, a greater yield is inevitable.
  • Those growing fewer plants can achieve similar yields by allowing those plants to grow big enough to fill the space. However, the plants may have to stay in the vegetative stage a bit longer before they reach their final size. Depending on your time constraints, this may delay the harvest and reduce the number of crops per year. In many areas, growers can only have a certain number of plants, but they can maximize yields with manifolding and other training techniques.

Maximize the Canopy

No matter the size of the grow room, it’s important to maintain a full, lush canopy. The easiest way to do it is to use the SCROG (screen of green) technique. Here, the plants are woven through the netting, filling each hole and creating uniformity of height and shape.

Many growers pinch the plants’ tops during the early growth phase. By pinching these tops instead of shearing them off, the plants can keep their main branches while the side branches grow level with the top. The plants suffer less stress, and it’s easier to achieve a consistent canopy.

To maximize light penetration within the green canopy, de-leaf the plants about one week into the flowering phase. This allows the overhead light to get deeper into the plants, increasing bud size and creating a bigger crop of flower.

Supplement With Phosphorus at the Right Time

As the first week of the flowering phase ends, it may help to give the plants a bit more phosphorus. Many growers do it in two feedings, at around the eighth and 13th days of flowering. By giving the plants a little extra phosphorus, you’re telling them to stop stretching and to start producing more bud sites.

Use CO2 to Increase Yields

Most cannabis cultivators are aware of the beneficial effects of CO2 supplementation. We suggest giving your plants 1250-1350 ppm throughout the flowering phase, gradually increasing the dosage from week one through week seven.

For the final week, though, try dropping the carbon dioxide level down to about 1000 parts per million to increase trichome production. Carbon dioxide speeds up photosynthesis and nutrient consumption while boosting resin production. You should see your auto bruce banner or gorilla glue strain plants respond with faster vegetative growth that will support more glorious buds.

Maximize the Root Zone

The bigger and stronger the roots are, the healthier a plant will be, and with size comes an increase in yield. Consider using boxes and adding more plants to create a larger root zone. Whether you’re using a closet or a dedicated grow room, it’s important to help the plants use the space to its full potential.

Don’t Take Shortcuts

The biggest and best yields start with a firm foundation built on quality soil and supplements. Being an indoor cannabis cultivator is like building a new home, and shortcuts can be risky. A high-quality growth medium and fertilizer will help to maximize yield by creating a healthy root zone. With healthy roots, plants will grow vigorously from germination to harvest.

Invest in a PAR Meter

PAR or photosynthetically active radiation is the light spectrum that only plants can see. To optimize growth at every stage and maximize yield, you’ll need to see light like your cannabis plants do.

Take light measurements everywhere and map the space accordingly. Consider the PAR output of each fixture in the grow room so you’ll understand what the plants are experiencing. Once you’ve created a PAR chart and a map, it’s easier to predict growth, nutrient requirements, and other factors.

If it’s within your budget, purchase a PAR meter with data logging capabilities. Then, set it up and let it run until its memory is full. The data gathered during a growth cycle will provide standard deviations and other information that, when used properly, will improve yield predictions with time.

Assess Nutrient Solubility Frequently

Before introducing a new ingredient to the crop, perform a spot test. Simply put a bit of the material in a dish and mix it with cold and/or hot water. See how it behaves and allow it to sit for a while. If the nutrient sinks to the bottom, it isn’t very soluble. Though a tissue test may tell you that the plants are well-fed, a nutrient that falls out of solution is useless.

Growers should understand the effects of pH on the availability of nutrients. A nutrient chart will provide information on the solubility of various micro and macronutrients, as well as their behavior under varying pH conditions. Learn how solubility changes as the pH fluctuates and apply that knowledge to your indoor grow op.

Calibrate Instruments Regularly

No matter how much you spend, a meter is only as effective as its last calibration. Learn each meter’s calibration standards and apply them often. If possible, calibrate meters each day and follow the guidelines precisely. This rule applies equally to pH meters, water meters, PAR meters, and any other instrument that provides data used during the decision-making process.

Grow Cannabis According to Your Needs

Before cultivating cannabis, you should know the market. If you’re growing weed for quantity rather than quality, the cultivation process will work a certain way. However, if the goal is to yield the biggest, freshest, and best-tasting buds possible, things will be a little different.

In most grow rooms, cultivators are working toward the growth of flower that looks great and has a high THC content. To accomplish this objective, they must train the plants, so the highest possible number of buds are exposed to the light. Most growers do this by spreading the plants apart and pinching the tops when they’re still growing, so they’re more likely to branch out far and wide. It also helps to start with high thc weed seeds from a reputable USA seed bank.

Get Ready for a Bountiful Harvest

If you’re growing marijuana seeds for the first time, harvest planning is crucial. An indoor grower isn’t at the mercy of the elements, so they may have a substantial amount of flower that’s ready for harvest in just a few short weeks. The work doesn’t stop when the buds are picked, though. You’ll have to trim it, dry it, and cure it to ensure maximum quality. If the grow op is planned properly, you’ll have a nearly constant supply of harvested material to process before the next crop comes through.

Protect the Crop From Pests

Growing indoor cannabis seeds doesn’t provide immunity from pest infestation. When bugs find their way in, some are hard to eliminate without the use of toxic chemicals. However, there are all-natural, safe ways to manage pests and improve the taste and quality of the final product. With companion planting and the introduction of natural predators, you’ll be able to keep pests under control.

Final Thoughts on Increasing Crop Yields

Numerous factors affect crop yields when growing marijuanna seeds, but those mentioned in this guide have the biggest impact. Though getting things right may take time, trial, and error, the effort is worthwhile. By following these rules, you’ll enjoy bigger and more potent yields than most growers believe possible.
