If you consider yourself a seasoned grower, you may be looking for a challenge to make your routine more interesting. This kind of experience can improve your growing skills and let you dive deeply into the farming craft. Moreover, it can allow you to explore some rare strains that are difficult to find on the market.
Most of the commercial farms do not want to bother with “difficult strains” that have long flowering periods, produce low yields, or require special growing conditions. Anything that may increase the time, money, or labor spent on cultivation would also raise the price for the final product, and that may be economically unviable for a growing company.
However, when growing for personal use, you may find such plants more interesting as they develop your skills. Among the challenging types of weed, you may find landrace strains (those that were selected among the feral strains without hybridization and were naturally adapted to the local environment) as well as some modern hybrids.
Here, we describe five strains that are considered to be difficult to grow and that some ambitious growers would like to try to “conquer.”
This landrace strain was named in honor of the longtime cannabis advocate, author, researcher, and Harvard professor Dr. Lester Grinspoon. It is a pure sativa bred by Barney’s Farm in Amsterdam, and it is known for its quality of flavor and potent cerebral effects.
The reason why Dr. Grinspoon is not popular among growers is its long flowering period, which usually varies between 13 and 14 weeks. Not only does it take ages to produce a harvest, but its buds can also give you reasons to worry. The long and thin stems are very fragile and brittle, the same goes for the buds, and you will need a lot of patience to receive the yield from your garden. Not that this plant can provide you with a large harvest (only about 350 g/m² when growing indoors), but the quality of these buds will allow you to consider them the gems of your weed collection that can impress even the most experienced consumers and cannabis connoisseurs.
This sativa is a landrace strain that takes its origins from Colombia's highest peaks―the Santa Marta mountain range. In its motherland, Colombian Gold is growing in a very rich and fertile soil and has all the conditions to grow tall and branchy. However, if you are growing indoors, the large stature of the strain can be a real problem―quite soon, it will take up all the available space and crave for more.
For this reason, it is recommended to grow Colombian Gold outdoors, especially since the yield from the outdoor plants is bigger than the one you can get from growing indoors (450-600 grams against 350 grams). However, even when growing outdoors, you should be prepared for your cannabis to rise above all the plants like a palm tree. So if you want to keep your garden in secret, you should be ingenious with the cover-up.
Another difficulty you will face is a prolonged flowering period, which in some cases may reach 90 days. It means that harvest time comes by the end of November, when in most states the conditions are inappropriate for growing plants outdoors. This strain definitely does not like impatience, but your waiting will finally be rewarded with a tasty and potent yield with an intense, sweet aroma and strong psychedelic effects.
This strain is a hybrid from California that provides you with a strong body and mind pain relief teasing your senses with a candy spice flavor and lemon aroma. Like most of the OG strains, SFV OG requires special feeding conditions. These plants need a lot of nutrients rich in calcium and magnesium. However, it is also possible to overfeed the plants so you should be careful with it.
Apart from that, SFV OG has a very dense structure, so to avoid the appearance of mold or pests, you had better prune the plant and get it topped at an early age. After the eight weeks of flowering, you will get about 150-300 grams per plant.
Bred by crossing two legendary strains OG Kush and Sour Diesel , Headband has a smooth, creamy smoke with lemon and diesel notes, and its long-lasting effects can easily help you treat a great number of conditions, including chronic pain and stress.
Headband grows fast during the vegetative stage, produces lots of tops, and does not require any special nutrients. The only thing that growers may find difficult is harvesting this strain. Its dense, large colas are covered with small buds that are quite difficult to take off. Applying the SCRoG technique at some point may help the issue.
This sativa-dominant hybrid has an amazing taste and aroma of chocolate, coffee, and a bouquet of Thai spices. Having almost no side-effects, Chocolate Thai will provide you with a strong cerebral high that leaves you happy, energetic, and creative.
The main difficulties in growing Chocolate Thai are its stalky structure, small yield, and typical for the Asian landrace strains long flowering period that lasts up to 100 days. The yield is usually very poor regardless of the place you are cultivating it or the methods you apply. The buds are spindly, with somewhat clumsy strings growing on the subtle main floral cluster. That is why it was so popular to make Thai sticks back in the 1970s and 1980s: it gave the buds a chance to look nicer and not so skimpy. However, the potency of the strain makes all the efforts worth trying: Chocolate Thai definitely has something for any consumer to enjoy.
