MARIJUANA SEEDS FOR BEGINNERS

There is a lot to learn when you start growing cannabis for the first time. Not all strains grow the same and some are less forgiving than others of mistakes that can easily be made. To make your first grow that little bit more enjoyable, we have selected a range of beginner friendly cannabis seeds. These strains can be easily maintained indoors, have inbuilt resistance to mold and pests and are vigorous enough for growers of all experience levels.

WHAT TO CONSIDER BEFORE YOU BUY CANNABIS SEEDS

There are literally thousands of types of cannabis strain that you can grow, from Indicas to Sativas to autoflowers. Every type will produce a very different marijuana plant so it's important that you take a few things into consideration before starting your home grow.

FEMINIZED OR AUTOFLOWERING SEEDS

Feminized (photoperiod) cannabis seeds flower according to light cycle and grow much bigger than autoflowers, however they take around 16 weeks to grow from seed to harvest. Autoflower seeds, on the other hand, flower automatically at around weeks 3-5, regardless of light changes. The resulting plant is much smaller but grows from seed to harvest in as little as 8 weeks and is easier to maintain indoors.

FEMINIZED CANNABIS SEEDS

Pros: Feminized marijuana seeds produce larger yields, high THC levels, and more control over the plant's growth cycle. Cons: Requires different light cycles, longer cultivation time and is more difficult to maintain indoors in smaller spaces. Best Suited For: Experienced growers seeking higher yields, outdoor growers or those with plenty of indoor grow space.

AUTOFLOWER CANNABIS SEEDS

Pros: Easier to grow, faster harvest, and less dependence on light cycles.

Cons: Smaller yields and slightly less potent. Best Suited For: Beginners, or growers with limited space or those seeking a quick turnaround.

INDICA OR SATIVA

Sativa and Indica cannabis seeds produce plants with very different effects and visual characteristics. Sativas grow tall with narrow leaves and offer a cerebral, energizing high. They're usually preferred for daytime use, aiding creativity and focus. However, their longer flowering time and larger space requirement can be challenging for inexperienced growers. Indica seeds produce shorter, bushier cannabis plants with broad leaves. They provide a more relaxing and sedative effect which is usually preferred for evening use. Their shorter flowering time and compact size make them easier to grow in smaller spaces. Alternatively, if you can't make up your mind, we stock a wide range of hybrid seeds which offer a blend of both characteristics in one plant.
