8 Tips for Growing Lemon Kush Marijuana [Grower’s Guide]

All you need to know to grow this zingy citrus strain


If you enjoy the citrus aroma and taste of Lemon Kush and would love to cultivate it at home, you’re in luck! In this growing guide, we show you how to grow this wonderful strain, which was created by Alien Genetics. It is a cross of Afghan Kush and Lemon G, and it is now possible to grow it yourself. However, the original version is no longer available as a clone or seed. Fortunately, you can grow a ‘new’ Lemon Kush which is a cross of Lemon Joy and Master Kush.

This strain is a balanced hybrid with a THC content of up to 26% and a CBD content of 1%. As you can tell by the cannabinoid content, Lemon Kush is not for newcomers. Users know that this strain provides an unusual sensation. While it will help you relax, it also hits you with a shot of energy, much like a strong cup of coffee. When you have taken a few hits of Lemon Kush, you’ll want to get things done, and possibly feel euphoric while you do them.

This is a popular medical cannabis strain for daytime use. Its CBD content aids its apparent healing capabilities which include relief from the pain caused by headaches, muscle spasms, and joint problems. It is also prescribed to patients with high-stress levels. Now that you have an idea of what Lemon Kush is and what it does, keep reading for some useful tips and tricks on growing it.

1 – Growing Lemon Kush – Indoors or Outdoors?

If you decide to grow outdoors, make sure you use premium quality soil. Do this, and you’ll benefit from a powerful lemon scent, not to mention an extraordinarily large yield. To grow Lemon Kush outdoors, you must live in a warm and dry Mediterranean climate. The crop is normally ready for harvest by the beginning of October, and the yield could be up to 35 ounces per plant.

Although indoor growing is much easier, you end up with a significantly lower yield of up to 18 ounces per square meter planted. It has a flowering time of 8-9 weeks and grows better in organic soil than hydroponic growing mediums such as Rockwool.

2 – Bring Out the Lemon Scent with Compost Tea

The alluring scent of Lemon Kush, along with its potency, are among the most coveted aspects of this strain. You can boost the incidence of both by adding compost tea to your soil. Its purpose is to add microorganisms which result in stronger, bigger, and more potent marijuana plants.

Compost tea is easier to make than you think. All you need is:

  • Compost (preferably with developed fungal colonies)
  • A nitrogen dense organic product such as fish hydrolysate
  • A product high in nutrients such as worm castings
  • A source of food for the fungi such as kelp
  • Food for bacteria such as molasses
  • A large bucket (at least five gallons)
  • An air pump with an aerator device at the bottom
  • A mesh bag (400-microns is best)

You can also buy a readymade compost tea brewer if you have the money. Overall, you should let your tea brew for around 36 hours. Dilute your tea so that it is one-part compost tea, 20 parts water, and add it to the roots of your plants. However, you can make the solution stronger if you wish because an organic compost tea won’t damage the roots.

3 – Higher Humidity is Okay

Unlike certain marijuana strains, Lemon Kush handles higher humidity levels well. Your seedlings can deal with a relative humidity (RH) level of up to 80%. During the vegetative stage, you can lower the RH to 65-70%. Once you force the plants into flowering, begin reducing the humidity level steadily. It should reach 50% RH within a couple of weeks, but you don’t have to lower it much more unlike other strains.

If you need to reduce humidity, try the following:

  • Increase the supply of cool air.
  • Water plants at first light.
  • Place a dehumidifier in the room.
  • Put your exhaust fan on the highest setting as it will push hot air that holds more water out of the grow room.

If you need to increase humidity, follow these simple steps:

  • Reduce the power emitted by your exhaust fan.
  • Purchase a humidifier.
  • Mist your plants during the vegetative stage. Don’t do it in the flowering stage or else you’ll increase the risk of bud rot.

4 – What About Temperature?

As a general rule, Lemon Kush enjoys a warmer climate. As a result, keep the daytime temperatures between 70- and 80-degrees Fahrenheit for as long as possible. Do not allow the night time temperature to fall by more than 10-15 degrees.

You must also be aware of the relationship between humidity and temperature. Your grow room’s temperature affects the amount of water vapor the air is capable of holding. Warm air can hold more moisture than cold air. Therefore, when you push temperatures up, you should push humidity down, and vice versa.

There is a difference between an RH of 70% at 77 degrees than at 68 degrees because the warmer air holds more moisture.Here’s a simple example, if you cool a 77 degree grow room by just four degrees, the RH in the room will increase from 70% to 80%. As you are lowering humidity during the flowering stage, it is only natural that the temperature in the grow room should be increased slightly. By the late flowering stage, for example, the daytime temperature should still be around 70-75 degrees.

5 – Why LED Lighting is the Best Option

If you’re growing cannabis for the first time, the sheer range of lighting and power options is overwhelming. You can purchase fluorescent lights, LEDs, Metal Halide (MH) lamps, High-Pressure Sodium (HPS) lights, and High-Intensity Discharge (HID) lighting.

First and foremost, choose a lighting type that provides a full spectrum of light similar to what is provided by sunlight. LED lighting is the choice of professionals because it provides dozens of spectra, and can be fine-tuned to any wavelength. LEDs are also cost effective because they last for years, and provide plenty of brightness without breaking the bank.

While other lighting types are high maintenance, LED lights seldom let you down. They don’t need replacement bulbs like Metal Halide and HPS lighting, and their chips don’t dim for the duration of their lifetime, which can be up to 50,000 hours!

6 – An Unusual Fertilizer

Are you against the idea of using chemical fertilizers? If so, consider using bat feces, also known as bat guano, to give your soil a boost. As well as fertilizing the soil, bat guano acts as a fungicide and activates compost. Since it is organic, it provides you with a far better tasting crop than if you use chemicals.

Fortunately, you can buy it at a gardening shop, so you don’t have to camp in a cave to find some! A good idea is to create a bat guano tea. Add three tablespoons of guano pellets to 3.5 liters of water, and you’re good to go. Leave the mixture for up to two days. Stir it thoroughly then add to your Lemon Kush plants’ soil three times a week.

Believe it or not, there are specific types of bat guano depending on the type of nutrients you need. For example, Indonesian guano is high in phosphorus and low in nitrogen. Jamaican guano is high in phosphorus, while Mexican bat guano is high in nitrogen.

7 – Other Manure Options

As Lemon Kush grows best in the soil, we’ve decided to focus on boosting the quality of soil in this guide. That’s why we’ve come up with a few more manure options if bat guano doesn’t tickle your fancy! Animal manure improves the growth of your weed during the vegetative stage and is cheaper than chemical fertilizers, and a whole lot better for the environment.

When choosing one of these options, it is important to complete a process known as ‘hot composting’ unless otherwise stated. Hot composting involves adding manure to a compost heap for up to eight weeks before it is added to the soil. You need to add water during this period and turn the heap every couple of weeks.

If you follow these instructions, you should be able to keep the compost’s temperature between 120 and 170 degrees. This warm environment kills parasites and other harmful organisms. It also eliminates any weeds that are in the form of seeds. As for animal manure options, here is an overview:

  • Chicken: This type of manure has almost 3% nitrogen in some cases and also includes phosphorus and potassium. Therefore, chicken feces contain the important NPK trilogy of nutrients. It can take up to nine months to compost it, but it is light and easy to transport.
  • Rabbit: You don’t need to hot compost rabbit manure. You can add it directly to the soil. It contains NPK, along with calcium, zinc, and magnesium. You will also enjoy the fact that rabbit manure doesn’t have much of an odor.
  • Pig: Unfortunately, commercial farming has resulted in a different method of feeding pigs. Whilst pig manure used to be a popular fertilizer, it now contains harmful bacteria. Hot composting solves the problem, and it is high in phosphorus.
  • Horse/Cow: Both options have reasonable levels of potassium and nitrogen. Again, you need to hot compost to get rid of pathogens.
  • Sheep: Sheep manure is odorless in pellet form and can be added to the soil right away. It is filled with potassium, and also contains nitrogen and phosphorus.

8 – Final Lemon Kush Growing Tips

There are so many aspects to growing that it is impossible to fit everything into just eight tips. As a result, we added some bitesize tips to round off this piece:

  • Prune young plants: Good pruning ensures all parts of your plant receive adequate light. It is best if you choose to prune in the vegetative stage because it causes mild shock to the plant and stunts growth for a few days.
  • Supercropping: This process involves bending the branches of main buds to ensure more nutrients reach the buds to make them heavier. Place a branch between your thumb and index finger, and start squeezing, gently at first. Keep applying pressure until you hear a cracking or snapping sound. When you do this properly, the branch will correct itself in a matter of hours.
  • Get your container size right: If the pot you choose is too small for the plant, it could stunt growth as the root system has nowhere to go. If you choose a large pot, it can take the root system too long to find the soil and reach the nutrients it needs. As a Kush strain, Lemon Kush needs a larger container than a Skunk strain because of its longer flowering period.
