Growing Indica vs. Growing Sativa Strains

When you are looking for the best marijuana seeds to help you get started in your growing endeavors, you might think that all strains are made alike. Not so fast! There are lots of differences between indica and sativa plants that you need to be aware of. 

Indica cannabis plants are native to India and high-altitude areas. Therefore, they are better suited for colder temperatures. They also have quicker flowering time, meaning your plants will mature more quickly. They are short in stature and produce a relaxing, sedating high that can be used to relieve pain, anxiety and muscle spasms. Indica is best for people who have limited growing space indoors. 

Sativa seed strain, on the other hand, are native to areas near the equator, where winters are mild and the summers are long. These plants grow more slowly, but produce more extensive growth. You’ll find that these strains are better suited for outdoor growth, as their height can be difficult to manage indoors. If you are an experienced grower who wants to explore the many strains and intricacies of marijuana available to you, you might want to consider growing sativa in your garden. 

Not only does sativa have faster vegetative growth, but it can handle lots of heat. It has some exceptional qualities, too, offering some of the purest characteristics for the user.

When To Harvest Sativa Buds?

Some sativa weed strains may need up to three months of flowering in order to be ready for harvest. This is when providing a typical 12/12 light routine. In this pattern, both daylight and nighttime hours are evenly split. Some variants, however, may need even longer nights on average. 

When you get closer to harvest, you are more likely to have buds that attempt to self-pollinate. If your buds appear like they are mostly done and this happens, just go ahead and harvest. The trichomes might never come amber-colored, a sign that they are ready to be harvested, even despite months of prolonged flowering time. 

Instead, harvest when your trichomes are cloudy and may have just a few clears left. This will allow for the greatest psychedelic effect. They should be milky white with some clears for maximum potency. Make sure you invest in one of the best bud trimmers in order to make light work of your harvesting chores.

  1. Am your number one fan. I love what you do. Keep the good job

  2. I need to know all this. My how things have changed since I grew hydroponically. Can’t wait to get started!

  3. oh, in fact, hybrid varieties play a role for me, which require not so much maintenance, because it is very important to devote less time to the plant. But this is pure for me, but hybrid ones are harder than natural species, so if you like to relax purely, then be sure to take natural flowers. The varieties are described quite accurately here: Jack Herer, Sour Diesel. This is true both in taste and sensation. Amnesia Haze is a very persistent flower, which is why they are often grown carelessly.
