How to Get 1 Gram/Watt, 6 Tips To Improve Your Indoor Grow.
Welcome to the exciting world of indoor cannabis cultivation, where efficiency and yield go hand in hand. Achieving 1 gram per watt is not just a benchmark for success; it’s a sustainable approach to growing that benefits both your wallet and the environment. In this guide, we’ll explore practical, tried-and-tested methods to help you reach this goal without needing to invest in costly equipment upgrades.
Let’s see if we can improve our yields; without spending extra money. Assuming everything goes to plan, it should be possible to harvest one gram per watt (or even slightly more) of power consumption from your grow light. So if that is not yet the case with you, then read on.If you want to harvest more weed after a few grows, you can choose the easiest way and invest in a new grow lamp. But more powerful grow lights cost money and also use more power. Not too good for the environment and also not for your wallet. Fortunately, you can also improve your harvest by simply gaining extra grow knowledge.
6 Tips To Improve Your Indoor Grow for 1 Gram Per Watt.
The first and possibly most important improvement is to realize that Light = weight is a mantra that weed growers who like to harvest as much as possible should definitely get into their head.
What does it mean? Simply put light is one of the most important determining factors for increasing the weight of your harvest. The magic number for most indoor marijuana growers is 1 gram per Watt in power consumption of your grow lamp.
If you get one gram per watt, you will be doing well as a grower. Half a gram per wat – for example 300 grams of dried cannabis bud from a 600 Watt HPS lamp – is an average harvest for a new grower starting out.
Let’s see if we can improve that; without spending extra money …
Selecting High-Yield Strains
The Foundation of Success: Choosing the right strain is crucial. While Indicas are known for their faster maturation and efficient yields, don’t overlook Sativas and hybrids, which often bring a desirable mix of traits. Strains like Critical+, Big Bud, Amnesia Haze, and Chocolope have earned reputations for their generous yields. Remember, it’s not just about size; consider factors like flowering time, resilience, and cannabinoid profile when selecting your strain.
Proven High Yield Strains.
Critical + and Critical + 2 from Dinafem and other Critical weed varieties always guarantee a big harvest, but Big Bud is also known for its enormous buds.
Amnesia Haze and Super Skunk and Power Plant are also doing very well in terms of revenue and Dutch Passions The Ultimate is also a good candidate when it comes to large harvests; we can recommend Chocolope from DNA Genetics and Serious Chronic is also another to consider when trying for 1 gram per watt.
Use all your space.
Optimizing Spatial Utilization
Making Every Inch Count: You don’t have to be an Einstein to realize that a full grow room yields more than an empty one. Take that thought a little further and you realize that a grow room whose entire surface is only filled with tops, therefore provides the maximum yield helping you to be well on your way to one gram per watt.
Whether you’re working with a large room or a small tent, efficient use of space is key. For smaller areas, the Sea of Green (SOG) method is ideal, allowing you to grow many small plants closely together. In larger spaces, the Screen of Green (SCROG) technique encourages horizontal growth and maximizes light exposure. Whichever method you choose, aim for uniform canopy development to ensure each plant receives equal light and air circulation.
If you want to harvest as much as possible, try to use the floor area as efficiently as possible by filling every square meter with plants. This can be four large pots or nine slightly smaller, or a sea of green with sixteen, twenty-five or even thirty-six pots per square meter. As long as you use the floor space well.
The same applies even more to the area above the ground. When you use a lot of plants you don’t have to do much as every plant has one main top, and with thirty-six plants per square meter, this can easily provide a sea of tops.
If you grow four plants you will have to let them grow for longer and also train them to ensure that they form a smooth even surface of buds. Topping and scrogging are the appropriate methods to achieve this.
Use the space not only in width but also in height; make sure that all tops grow to the same height. This will ensure that the grow lamp is the correct height for all the plants…
Ideal Lighting and Sweet Spot
Lighting the Way to Higher Yields: Understanding your lighting system’s “sweet spot” is vital. For HPS lamps, a general rule is to maintain a distance of 10% of the wattage in centimeters (e.g., 60 cm for a 600W lamp). For LEDs, consult the manufacturer’s guidelines. Remember, the goal is uniform light distribution across the canopy, so adjust the height as your plants grow to maintain the sweet spot.
Whatever grow light you use, they all have a so-called sweet spot. That is the distance at which the lamp performs optimally.
A rule of thumb for HPS lamps is 10% of the Wattage in centimeters, eg a 600w HPS hangs 60cm above the canopy of your plants. A 400 Watt HPS lamp is 40 cm, a 250 Watt is 25 cm et cetera.
Energy-saving lamps and fluorescent lamps and other CFL lamps (Compact Fluorescent Light) you only have to hang an inch or so above your weed plants. With LED grow lights, the optimum height differs, but the manufacturer should supply info on what the sweet spot of your lamp is.
Find out what the sweet spot is and hang your grow lamp at this height. Make sure that the plants below are as similar in height as possible so that they all benefit from the sweet spot.
Optimize Your Grow Room Climate.
The healthier your cannabis plants are, the more they will give a heavy harvest. Improve Your Indoor Grow by making sure that you keep the temperature, air circulation and humidity as stable as possible and allow it to change with the life phase of your plants.
Climate Control in the Grow Room
Creating the Perfect Environment: Cannabis plants thrive in stable conditions. During the vegetative stage, aim for temperatures around 27°C (80°F) and humidity levels of 60-70%. In the flowering stage, cooler temperatures around 23°C (73°F) and lower humidity help develop dense, resinous buds. Keep day-night temperature fluctuations minimal and ensure good air circulation to mimic the gentle outdoor breezes.
Growing cannabis in the vegetation stage your plants can grow happily at around 27c (80f) and fairly high humidity (60 to 70%). Flowering plants prefer it a little cooler; around 23c (72f) and the lowest possible humidity, ensures that buds become nice and heavy and hard.
Try to keep the difference in temperature between the days and the nights as small as possible and ensure good air circulation in your grow room. In nature, the tops that catch the most wind are usually the thickest but don’t overdo it. Gently move your plants with a fan and aim the fan just a little above the foliage. Preferably use a fan that swings.
Get The Nutrient Balance Right for one gram per watt.
You should not compare plant food with human food. It is not the case that the more nutrition you give, the bigger your plants will become. This is only the case with light for plants (light is weight!). You can better compare food with vitamins. You need them but don’t grow from them. Look carefully at your weed plants and feed them based on the color of the leaves.
Dark green means that everything is going well and that they receive more than enough (but not too much) nutrition. Light green means that they can use more food. If the leaves have dark green leaves and burnt leaf tips, then you are probably giving too much. If they get burnt leaf tips after an (extra) feed, then you have probably given a little too much food. Get the nutrient balance just right and you will be on your way to 1 gram per watt.
What applies to food also applies to water management. The better balanced and the more stable it is, the better it is for your plant and your harvest. Only try to give new water when the top three centimeters of the earth has dried up.
You can also see from the leaves if they need water; ideally, they should be tilted upwards. If they hang down and they are limp, your cannabis plant will dry out. If they curl down but feel firm, then they almost certainly have too much water.
Balanced Nutrient Management
Feeding for Optimal Growth: Nutrients are vital, but more isn’t always better. Monitor your plants’ leaf color; dark green indicates sufficient nutrients, while lighter shades suggest the need for more. Be cautious with nutrient strength—overfeeding can lead to nutrient burn, indicated by dark green leaves with burnt tips. Balance is key; aim for steady, healthy growth rather than rapid spurts.
Pruning The Bottom Of Your Cannabis Plant.
The last thing to consider on your journey to improve Your Indoor Grow and getting 1 gram per watt is Pruning which is a growing technique that is as old as the hills and that because it works. Start by removing the buds and small branches at the bottom of the plant at the start of the flowering phase (two weeks after the plants are on 12/12 to be precise).
Effective Pruning Techniques
Directing Energy Where It Matters: Pruning is an art that directs the plant’s energy to the top-producing buds. Start by removing lower buds and branches that receive less light, especially in dense setups like SOG or SCROG. This practice not only focuses growth on the top colas but also improves air circulation, reducing the risk of mold and pests.
In the case of a Sea of Green or a scrog, this makes a lot of sense because the densely overgrown foliage often means that no light falls on these lower buds.
By removing them, they no longer steal nutrients and energy from the main buds. Removing the lower buds means that you have much less poor quality buds, reduces time spent cropping poorly developed tops and ultimately achieve a much higher harvest weight.
Conclusion and Encouragement
As you embark on this journey to maximize your indoor cannabis yield, remember that every grow room is unique, and experimentation is part of the process. Share your experiences, learn from others, and watch as your skills and yields grow together. Happy growing!
