8 Tips for Cultivating Green Crack Marjiuana: Grower’s Guide

Tips for wicked high yields!

When it comes to growing your favorite pot strain, it is important not to become impatient and skip the requisite steps. Otherwise, you may suffer from an inadequate yield or even worse – low-quality weed. In this growing guide for Green Crack, we will outline the best ways to cultivate this sativa-dominant (75%) hybrid.

Don’t be fooled by the name; Green Crack is a potent marijuana strain that is a cross of Skunk #1 and Sweet Leaf Indica. It was originally called Green Kush, but according to rumors, Snoop Dogg renamed it Green Crack because he found it extremely addictive. As you can probably tell from the name, this strain is known for its “energetic” tendencies.

As it is sativa dominant, it is an excellent daytime strain because it hits you with a powerful head high and sparks creativity and energy. Despite the high, though, many users become even more focused and uplifted. It isn’t unusual for Greek Crack lovers, in fact, to start their day with a smoke instead of a cup of coffee.

Green Crack is a strain with a uniquely pungent odor, offering a fruity yet earthy scent along with a delightful citrus taste. The aftertaste is among the best of any strain out there, so you can fight fatigue, become more creative, and have a lingering taste of the tropics in your mouth! Medicinally speaking, Green Crack has frequently been used to treat depression, chronic body pain, and stress.

1 – Green Crack is best grown outdoors

To be clear, you can grow Green Crack indoors because its indica component keeps the plant at medium height. The rapid flowering cycle of just eight weeks means growers still keep this strain indoors between temperatures of 70- and 90-degrees Fahrenheit. It produces up to 18 ounces per square meter planted, and you should be able to enjoy more than one indoor harvest annually.

If you elect to grow outdoors, you can only do so in a warm Mediterranean climate. Generally speaking, Green Crack is available for harvest by the end of September, and you could benefit from a yield of up to 20 ounces per plant! You can nudge harvesting to early October, but make sure no more than 75-80% of the pistils change color or you risk losing potency.

2 – Add more Phosphorus early in the flowering stage

If you’ve ever grown any form of marijuana, you’ll understand the importance of adding the right nutrients at the correct time. The three most important are Nitrogen (N), Phosphorus (P) and Potassium (K). Green Crack strains follow the conventional wisdom that you must feed it a greater degree of N in the vegetative stage.

Where Green Crack is different is at the end of the vegetative stage. Once you force your plants into flowering, it is essential that you significantly increase the level of Phosphorus they receive. Ideally, you will begin adding P even before the flowering stages begins. If you do this correctly, you will be rewarded with buds so fat you won’t be able to believe your eyes!

3 – Learn to spot nutrient deficiencies

Nutrient issues are the bane of any marijuana grower. It is essential to ensure that there is an accurate pH balance in the water and soil. Each nutrient you add or subtract will make the soil more acidic or alkaline. Frankly, it is more common for growers to overfeed their plants, but if you don’t provide the right nutrient levels, your plants will suffer.

Here’s a quick guide to spotting deficiencies per nutrient:


Phosphorus (P)Signs include slow growth and darkening leaf colors. Eventually, the Green Crack plant’s leaves will curve towards the plant and offer a brown, almost tan color. Failure to add enough P during flowering will reduce the yield.
Nitrogen (N)A marijuana plant with a Nitrogen deficiency will have yellow leaves which soon begin to curl up and die.
Potassium (K)A potassium deficiency can surprise you because initially, your plants look bigger and more vigorous at first glance. Upon closer inspection, though, you’ll find that the bottom leaves are dying. Eventually, chlorotic spots appear and it may already be too late to deal with the issue by then.
Calcium (Ca)Calcium depletion is a major problem for plants grown outdoors, and is also an issue when using hydroponics systems. You can spot a calcium deficiency via green blotches that appear on the leaves. The branches are also weaker and snap easily.
Copper (Cu)This is one of the most serious deficiencies because it causes necrosis (death) of young leaves. The result is a gray or, ironically, a copper color at the tips of the leaves.
Iron (Fe) This is another common deficiency that severely impacts new growth. Lack of iron tends to affect the upper leaves which become yellow.

4 – Avoiding mold

One of the problems you’re likely to face is the presence of mold, especially if you grow outdoors. Gray mold is especially deadly because it damages practically every part of your Green Crack plant, including the buds, flowers, stems, and stalks. Gray mold doesn’t care which part of your plant it ruins, and it often ruins all of it. Just to be clear, it can kill everything in its path, including seeds.

| “The presence of mold in your Green Crack grow can kill everything in its path, including seeds…”

Mold is at its worst in temperate or cool climates where the temperature is below 70 degrees. This shouldn’t be an issue if you grow outdoors in a warm location, but humidity also has a major say in whether gray mold shows up and spreads.

If you grow Green Crack indoors, make sure you change clothes before entering the grow room. Believe it or not, spores can latch onto clothing and spread in your weed room after finding a host (your plants). Failure to deal with gray mold quickly will have devastating consequences, as it can destroy a crop in a week!

You can spot gray mold by looking for a brownish-gray mass of mycelium. Next, it gets covered by fungal spores, and it smothers your plants, turning them yellow. As well as keeping the temperature high and humidity below 50%, you can prevent bud rot by trimming a few leaves to increase their exposure to light.

It is also a good idea to water your plants during the day to give them time to dry before the temperature drops at night. If you spot grey mold, use an oil spray with sesame or neem oil or use Potassium Bicarbonate to keep fungi and mold from growing. Unfortunately, if you see a plant that is clearly damaged, you have to remove and destroy it to stop the infection from spreading.

5 – Improve indoor ventilation

Gray mold doesn’t like areas that are well ventilated with good airflow. In simple terms, your plants grow best when you operate a ‘cool and fresh air in, stale and hot air out’ system. If you get ventilation wrong in your grow room, fungi, mold, and bugs will thrive and ruin your crop.

If you grow outdoors in the right climate, the wind circulates the air so your Green Crack plants should have no issues growing strong and healthy. If you’re using a grow tent, you need to develop a ventilation system, which will probably be dictated by the lighting you use.

Above all else, make sure you have an exhaust fan, duct tape, ducting, and an intake fan. The ducting has to be the correct size for your grow room, or else you’ll require reducers and clamps. Line the ducting up with your exhaust fan and attach with duct tape. Run more ducting through a hole in the tent and attach a carbon filter to the extractor fan and place it on the roof.

Any outside ducting you use needs to be connected to a window or vent to exhaust hot air from your room. To maintain good airflow inside, consider using an oscillating fan or clip-on fans. As a rule of thumb, air needs to be exchanged every 60-120 seconds if you intend on maintaining optimal humidity and temperature.

| “For a top-notch Green Crack grow, air needs to be exchanged over the plants every 60-120 seconds for optimal humidity and temperature.”

Place your intake fan at ground level if possible to connect to the hole you should have created in the bottom corner of your room. Once again, ensure the ducting is straight and secure it in place with duct tape. The outside ducting must connect to a fresh air source such as a window or vent.

6 – Watering

All life on this planet requires water to survive. However, resist the urge to overwater your Green Crack plants, as excess hydration can quickly lead to root disease.

Also, when germinating the seeds, make sure the top layer of the soil stays moist but don’t overdo it. Once your plant sprouts, make sure the area near the stem remains dry. Excessive moisture could result in stem rot.

When you overwater your plants, you place undue stress on them, which hurts yield and potency. Moreover, when the soil is too soggy, it restricts your plants’ oxygen intake and could ultimately kill them. The main problem with watering is that the symptoms of overwatering and underwatering are almost the same; your plants’ leaves droop in both cases.

Regularly inspect the soil’s moisture level by feeling the surface. If it feels damp down to an inch, avoid watering the plant. If the soil feels extremely dry and crumbly, it is time to water your plants. Although you can use tap water to grow your weed, it could be a bad idea depending on where you live. In some areas, a huge amount of chlorine is added by the municipal water supply which is great because it doesn’t hurt your plants and actually kills harmful bacteria.

DID YOU KNOW: Using tap water to water your Green Crack plants can be damaging to the crop if it contains too much Chlorine?

On the other side of the coin, your supply could be what is called ‘hard’ water, which contains a buildup of minerals. Again, this isn’t necessarily a bad thing, but avoid using artificial water softeners because they normally result in the soil receiving too much sodium which does harm your plant.

7 – Maintaining high-quality soil outdoors

Like most marijuana strains, Green Crack works best in a high-quality soil where it has lots of space for its roots to develop. If you elect to grow outdoors, don’t assume that the soil outside is ideal for growing weed. It is essential for you to test the pH of the soil to begin with, to ensure it is not too acidic or alkaline. Most experts recommend growing cannabis plants in soil with a pH of 6.3 – 6.8 or thereabouts.

If the soil is too alkaline or acidic, you can always add a pH UP or pH DOWN solution to ensure you get the right balance. Composted material makes for excellent natural fertilizer, and you can use anything that was once organic. For example, banana peels, dog feces, and even leaves can be used to create compost to feed your plants. The key is to prepare, because it takes some time for the organic matter to decay enough to use as fertilizer.

| “Composted material from organic food waste makes for excellent natural fertilizer for your Green Crack plants.”

If the pH levels of your soil fluctuate, it is sometimes a case of chemical contamination. If this happens, you should perform a ‘soil flush’ to balance its pH and reduce contamination. However, most growers agree that soil flushing is a last resort when your Green Crack plant is in danger of dying.

To perform a soil flush, place your plant in a sink and turn on the faucet so that the water runs through the soil and eliminates harmful contaminants. As you can guess, the chief danger here is oversaturation.

8 – Lighting

All strains of marijuana require enormous amounts of light. In fact, if it is possible, try to keep the lights on (if indoor growing) for 24 hours a day while your Green Crack plants are in the vegetative stage. If you have a large grow room, invest in adjustable light tracks because you can move them to any part of your garden. This way, your plants get enough light and your electricity bill isn’t suspiciously high.

Also, it is crucial to ensure that the lights are not too close or far away from the top of the canopy. Experts suggest that a distance of 20 – 30 inches is ideal. Keep an eye on the distance because your plants will grow daily and their tops will instinctively reach upwards in a bid to find the light. Therefore, it will be necessary to move the lighting regularly to avoid burning the tips of your plants.

It is also a good idea to install a water-cooled system that reduces the heat produced by the lights. As you know, electric light bulbs produce both light and heat when switched on, and if they are powered on for at least 18 hours a day, they become incredibly hot. With a cooling system, you benefit from ample light for your plants while ensuring the grow room temperature doesn’t reach excessive levels.

It is also a fact that certain lights emit different color spectrums. ‘Visible’ light relates to the colors we see, such as the seven colors of the rainbow. Your Green Crack plants will thrive if you use lighting that is very strong in the ‘red’ spectrum because it boosts photosynthesis, a process that is crucial for tissue production during the vegetative stage. For the record, high-pressure sodium lights, better known as HPS, produce the most ‘red spectrum’ light and are ideal during every stage of your plant’s growing cycle.

| “Green Crack plants thrive under lighting that is strong in the ‘red’ spectrum, as it boosts the natural process of photosynthesis.”

It is equally important to avoid all lighting in the ‘green spectrum.’ Why? Because your marijuana plants completely reflect this type of lighting; that’s why they have a green color themselves! If you expose your plants to ‘green’ lighting, the result is low-yield plants with wilted leaves. If you’re growing outdoors, you don’t typically need to worry about light — as long as you live in the right climate for Green Crack to thrive.
