8 Tips for Growing Pineapple Kush: Grower’s Guide


Pineapple Kush is widely regarded as one of the best pain-relieving marijuana strains on the market. It is a cross of Master Kush and Pineapple and inherits the tropical taste of one of its parents. It is a near balanced hybrid with a THC content of approximately 21% and about 0.2% of CBD.

If you are new to marijuana, Pineapple Kush is a great place to start. Despite its high THC content, the cerebral high is more on the mellow side. It isn’t too heavy on the body either, and it will enable you to feel relaxed but not glued to the couch. It is an excellent option if you are suffering from stress, and it is associated with a sense of euphoria that makes you feel creative and inspired.

Its analgesic properties are well documented, and Pineapple Kush is a favorite amongst those who suffer from muscle pain and fatigue. You can also use this hybrid to boost your appetite or help treat anxiety and depression. If Pineapple Kush happens to be your favorite strain, read this growing guide for tips and tricks on cultivating this marvelous variety

1 – Should You Grow Pineapple Kush Indoors or Outdoors?

Pineapple Kush is classified as an easy strain to grow if you are a novice. It is recommended that you grow this strain indoors because it is far easier to keep control over the climate. Pineapple Kush is resistant to mildew and common molds and is a fairly tough plant. If you grow it indoors in a controlled climate, the flowering time is approximately 8 weeks and should yield up to 18 ounces of cannabis per square meter.

In the event you grow it outdoors, the yield will be around 20 ounces per plant. It should be ready to flower in late September or early October.

2 – Pineapple Kush’s Ideal Temperature

Your grow room’s temperature is essential for the photosynthesis of your crop. If the temperature is too low, it reduces evaporation through the leaves. As a consequence, the suction force which helps the roots take up nutrients is reduced. When that happens, the unabsorbed nutrients remain in the soil or hydroponic growing medium, damaging the root environment.

Meanwhile, the growing medium’s increased acidity further halts the absorption of nutrients and growth soon ceases altogether. In photosynthesis, plants use CO2, water, and sunlight to create sugars which are sent to various parts of the plant. When the daytime temperature falls below 68 degrees Fahrenheit, it causes these sugars to get stuck. As it happens, Pineapple Kush thrives with an average daytime temperature between 68 and 80 degrees.

3 – The Humidity Question

Plants respire CO2 from the environment via their leaves and lose a significant amount of water in their foliage. Did you know that marijuana plants evaporate approximately 90% of the water they absorb? The air holds a certain amount of water, and once the limit is reached, you see condensation.

The temperature of your grow room impacts the amount of water vapor held by air. Cold air is unable to hold as much water vapor as warm air. As a result, a relative humidity (RH) reading of 70% is different in a grow room at 68 degrees than in one at 73 degrees. In general, you should keep humidity between 65% and 80% during the seedling stage.

As Pineapple Kush handles high humidity fairly well, you can stay on the higher side of the following ranges, but make sure you reduce the temperature too. In the vegetative stage, for example, you can drop the RH to 55% if the temperature is 80 degrees. If the temperature is 70 degrees, you can increase the RH as far as 70%.

During the early flowering stage, RH should be between 40% and 50%. Again, 50% is fine at a temperature of 78 degrees, while 40% is okay at 70 degrees. By the late flowering stage, it is best to keep RH levels below 40% because the temperature will normally be around 75 degrees or so at that point.

4 – Consider Trellising

Whether you grow Pineapple Kush in soil or hydroponically, you will need to train the plants to ensure good airflow to the canopy. We recommend using the Sea of Green (SOG) training technique. If you want better growth in the top colas, prune your plants by removing unnecessary branches and fan leaves.

Pineapple Kush tends to have fat buds, so if you don’t have the right support, they could topple over. Trellising can keep your plants growing tidily and prevent them from toppling over. You can purchase a trellis online or make one yourself using nylon and plastic if indoors, or wooden posts if outdoors.

Vertical trellising involves attaching the device to a wall to promote vertical growth, like vines. Typically, only commercial and outdoor operations grow vertically. The more common horizontal method is better known as the Screen of Green (SCROG) technique. A couple of weeks before the plants are due to flower, install a screen with 2-inch square gaps directly above the plant canopy.

You need to ensure the plants are well pruned and thinned out for trellising to work. Once the plants grow through the screen, you bend and weave the shoots to promote neater growth. You can continue using the trellis until about halfway through the flowering stage.

5 – Feeding This Hungry Plant

Pineapple Kush inherits its appetite from its OG genetics. Most growers know all about the importance of using Nitrogen, Potassium and Phosphorus-rich products. However, aside from NPK, Pineapple Kush needs a good CalMag supplement (Calcium and Magnesium) and should also be fed sulfur, zinc, iron, chlorine, manganese, and cobalt amongst other things.

While nutrient burn is a problem with many varieties of marijuana, Pineapple Kush doesn’t have that issue. By all means, check for nutrient burn symptoms such as burnt tips of leaves, but in general, don’t be afraid to feed your plants heartily. Focus on high nitrogen in the vegetative stage, and dress the top of the soil with phosphorus & potassium when it begins to bloom. You should flush the plants a week or so before harvest to ensure there is no nasty chemical taste from your weed.

6 – Interested in Growing Organic Cannabis?

Chemical fertilizers and hydroponic growing mediums can take a lot of guesswork out of the growing equation, but it is bad news for the environment. If you want to try growing organic weed, you need naturally amended soil as your growing medium. You can ‘build’ your own super-soil by adding amendments such as compost tea, bat guano, fish emulsion, kelp meal, peat moss, and worm castings.

Feeding your organic Pineapple Kush is a case of finding clean water. A reverse osmosis system will purify your water. The trouble with municipal water supplies is that they are laden with chemicals such as fluoride which kill helpful bacteria. Whatever amendments you add, make sure your plants receive ample NPK, along with calcium, magnesium, and manganese.

7 – A Brief Note on Hydroponics

There are plenty of reasons why you should grow Pineapple Kush, or any other strain, hydroponically. You can get higher yields from a smaller grow room, there is less risk of pests and disease (as long as all equipment is sterile), and you can customize watering and nutrient timescales.

However, it is not all roses as some guides seem to suggest. First of all, a good hydroponics system isn’t cheap. More pertinently, a greater degree of skill is required because you must have decent knowledge about plant nutrition, and a clue of how a hydroponics system works. If a complex nutritional problem happens, do you have the nous to fix the issue?

Although there is less chance of diseases and pests ruining your crop, IF pathogens get into your grow rooms, they will spread at rapid speed. Therefore, hydroponics is not a good option for your first ever grow. Pineapple Kush is hardy, but if you make several mistakes, your crop could perish!

8 – Is it Worth Your While Growing Pineapple Kush?

To be honest,the answer is usually the same regardless of the strain. The price can range from $200 to $300+ per ounce depending on where you live. Although you could create a small setup for a few hundred dollars, it normally costs more than $1,000 to purchase the kind of equipment that allows for a decent-sized grow.

If you are only likely to use a few ounces in a year, it is probably not worth growing Pineapple Kush, unless of course,you want the experience of cultivating marijuana (which is priceless). Hydroponics systems cost more than if you use soil, but there are ample options for under $500 and a handful for below $200. If you need medical marijuana, use quite a lot, and have time on your hands, growing a crop of Pineapple Kush is not just worth the cost, it is extremely fulfilling!
