8 Tips for Growing White Rhino Cannabis: Grower’s Guide

If you have ever wanted to learn how to grow your favorite strain, you’re in luck! At WayofLeaf, we have hundreds of growing guides, helping you expertly cultivate cannabis strains.

One thing to remember is that the method you use to grow cannabis significantly alters the end result. Therefore, you may grow a White Rhino strain in soil that differs from one a friend grew hydroponically.

Whatever growing setup and techniques you want to learn about, we have it covered. Read on to find out more about how to grow the White Rhino strain.

Tip #1 – Strain Review: How Potent Is White Rhino?

White Rhino is almost entirely indica with a THC content of up to 22%. This strain came second at the High Times Cannabis Cup in the Bio-Cup category in 1996.

Cannabis breeders Green House Seeds developed this strain by crossing a North American Indica and White Widow. Overall, White Rhino’s lineage consists of landrace strains from South India, Brazil, and Afghanistan.

Users generally experience a cerebral high coupled with a powerful body buzz.

White Rhino’s effects are fast-acting. Users generally experience a cerebral high coupled with a powerful body buzz, followed by potent sedative effects. Along with a significant head rush, users report feeling happy and invigorated for a couple of hours.

Medicinal consumers say that White Rhino is an excellent analgesic. Some painful conditions that it may alleviate include joint pain, muscular aches and pains, and migraines. The White Rhino strain may also address insomnia, depression, and loss of appetite. However, be careful not to over-consume this strain as you may experience some side effects. These include cottonmouth, dry eyes, dizziness, paranoia, and a headache.

Tip #2 – Growing Difficulty

The growth difficulty of this strain is easy to moderate. Cultivating White Rhino is relatively uncomplicated, and it can grow in most environments without too many issues. Prune and trim the plant’s leaves and branches as and when necessary. Diseases such as bud rot are less of a concern because this strain is naturally highly resistant to disease.

Tip #3 – Best Growing Techniques for White Rhino

White Rhino seldom grows taller than six feet, and it typically only reaches this height with unlimited root space. If you grow White Rhino in 5-gallon containers, it is unlikely to exceed five feet in height.

A hydroponic setup tends to help indoor growers achieve the best yields. Additionally, it means you do not have to work with soil. With this growing method, the plants become bushier with less space between the nodes.

Although soil is cannabis’s natural growing medium, there are several disadvantages:

  • You might not be able to recycle soil
  • You must constantly monitor the soil’s pH level
  • The quality of the soil has a massive bearing on the outcome
  • Soil is susceptible to pests
  • Trying to determine the precise level of nutrients is not an exact science

With a hydroponics system, you use an inert growing medium such as Rockwool or coco coir. It is a good option for experienced growers who understand how to feed their marijuana plants. It is a trickier proposition for novices because you are solely responsible for adding nutrients. A high-quality soil, on the other hand, should give your plants all the nutrients they need.

If you are growing White Rhino indoors, consider a Sea of Green (SOG) setup if you have limited space. SOG is a growing technique that forces plants to flower at an early stage. In general, you will force flowering after White Rhino has been in the vegetative stage for just two weeks. Here is a simple SOG overview:

  • Germinate seeds or create clones by taking cuttings from a mother plant.
  • Expose them to 18+ hours of light per day until they are 12 inches tall.
  • Make sure the plants have enough space: No more than two plants per square foot.
  • When you see a dense canopy of buds, cut the branches underneath and use them as clones.

Tip #4 – How to Get the Highest White Rhino Yield

Light intensity is one of the main factors that have a bearing on the overall yield.

White Rhino typically provides a very high yield, but you can maximize it by increasing the intensity of the light. Naturally, be careful not to increase the light intensity so much that it causes light burn. If you have a small indoor grow, fluorescent lights such as CFLs are a good option.

An increasing number of growers use LED lights because they offer a fuller spectrum than the other available options. Make sure you carefully read and follow the manufacturer’s instructions. As a rule of thumb, keep LEDs at least 12 inches away. If you are using 3W or 5W models, make sure your plants are at least 18 inches away.

You can also use Metal Halide (MH) or High-Pressure Sodium (HPS) lights. However, make sure they remain at least two feet away from your White Rhino plants. The precise distance depends on the size of the bulb. Above all, make sure you have a decent cooling or exhaust system. This reduces the risk of heat stress and provides fresh CO2 to the plants.

Tip #5 – Best Feeding Options for White Rhino

White Rhino provides enormous yields, but that’s because it is a heavy feeder. Focus on providing lots of nitrogen during the vegetative stage, but don’t forget potassium and phosphorus! Your crop also needs secondary nutrients and micronutrients such as calcium, copper, boron, magnesium, zinc, and sulfur, among others.

Focus on providing lots of nitrogen during the vegetative stage, but don’t forget potassium and phosphorus!

If you are using a hydroponics setup, pay attention to the Electrical Conductivity (EC) reading. It is a measure of how strong a nutrient solution is and helps you determine how rich in minerals the water is. The EC reading will be higher the more minerals are in the water. A reading of between 0.8 and 2.0 is ideal for marijuana during its growing cycle.

Tip #6 – Should You Grow White Rhino Indoors or Outdoors?

White Rhino is often grown outdoors, and it will provide a higher yield in a suitable climate. However, it also grows smoothly indoors in a well-controlled environment. You will notice that this strain grows relatively short with tight buds covered in glowing white crystals. It produces a powerful scent during the flowering period. Therefore, make sure the air in your grow room is well circulated.

Tip #7 – White Rhino Flowering Time: When Should I Harvest?

Indoors, White Rhino’s flowering time is 9-weeks. This strain provides you with an enormous yield of 32 ounces per square meter. When you grow outdoors, White Rhino yields an astonishing 42 ounces per plant! It typically is ready for harvesting by the end of September or the beginning of October.

After months of hard work, it is crucial that you harvest your crop at the right moment. The pistil method involves waiting for at least half of the pistils on your plants to change color from white to reddish-brown. By the time 70-80% have changed color, your White Rhino strain is likely at its most potent.

However, the trichome method is arguably the most reliable. It involves using a magnifying glass such as a jeweler’s loupe. When the trichomes are still clear, the crop is not ready for harvest. Once a number of them turn milky-white, it is time to make a move.

Opinions differ about the perfect time for harvesting when using the trichome method. Some believe that you should harvest when 25% turn white, while others say wait until 70% have changed color. Don’t wait too long, however. If all of the trichomes turn amber, it means that the THC has degraded into CBN.

Tip #8 – What is the Best Climate for Growing the White Rhino Strain?

Ideally, you will keep the daytime temperature in the 68-80-degree Fahrenheit range. The key is to ensure consistent temperatures during the day AND at night. Ensure there is no more than a 10-15-degree difference between day and night temperatures (this means lights on and lights off when growing indoors).

White Rhino prefers a humid climate, as long as it is not exposed to too much rainfall.

Final Thoughts on White Rhino

If you are a grower with minimal space, White Rhino is a fantastic option. It provides gigantic yields, even if you shorten the growing time with the SOG method.
