What are indoor cannabis seeds?

Indoor cannabis seeds can be germinated and grown into plants which produce cannabis buds. Good quality indoor cannabis seeds are easier to grow than ever and deliver heavy harvests rich in THC, or any other cannabinoid you prefer such as CBD, CBG, CBDV, THCV etc. Most growers choose either autoflowering cannabis seeds or traditional photoperiod seeds. But some old school growers (or those wanting to produce their own crosses) can also grow regular photoperiod cannabis seeds.

Autoflower seeds take around 10-11 weeks to grow indoors. Usually they are grown under 20 hours of daily light from seed to harvest. Quality levels from the best autoflower seeds are as good as photoperiod feminised seeds and many growers feel that autoflower seeds are easier/faster to grow.

Photo-dependent feminised seeds don't start blooming until light hours are reduced to 12 per day. Whether you choose autoflower indoor seeds or photoperiod indoor cannabis seeds you can expect high quality harvests.


Best indoor feminised cannabis seeds

There has never been such a wide choice of indoor feminised cannabis seeds. Recent introductions with USA genetics have increased the diversity and quality levels on offer. Here are three of the top Dutch Passion feminised cannabis seeds.

Sugar Bomb Punch

Sugar Bomb Punch seeds are a proud member of the elite Dutch Passion Extremely High THC cannabis seeds collection. These can produce THC levels around 25% in optimum conditions. Indoor feminised cannabis seeds simply don't come much stronger than Sugar Bomb Punch! The indica genetics take around 9 weeks to complete bloom and are part of the USA Special cannabis seed collection.

Amsterdam Amnesia

Amsterdam Amnesia seeds use the best Amnesia genetics you can get, Amsterdam Amnesia! With very high THC levels and the classic Amnesia effects this is a strain that should be in everyone's seed collection.

Best indoor autoflower cannabis seeds

Autoflowering cannabis seeds have become the go-to genetics for any grower seeking a fast, heavy, high quality harvest with an easy grow experience. Dutch Passion are proud to have been one of the original autoflower seed pioneers and have collected numerous cannabis cups and awards for their autoflower seeds. Here are 3 top recommendations:

Auto Skywalker Haze

Fans of sativa indoor autoflower cannabis seeds will love Auto Skywalker Haze. With very high THC levels autoflower seeds don't get much stronger. The Haze genetics mean that Auto Skywalker Haze can take up to 12 weeks from seed to harvest. That’s a couple of weeks longer than other autos, but the wait is worth it for the XL yields of powerfully relaxing buds.

With THC levels officially (and independently!) recorded at over 25% this could be the worlds strongest autoflower seed. Heavy yielding with a long lasting and supremely powerful effect. Only suitable for those that can take the very strongest buds!

What makes a cannabis strain indoor or outdoor?

Some indoor cannabis strains can't be grown outdoors at all latitudes. They may lack the genetics to give them sufficient weather resistance at your latitude. Or they may simply take too long to finish outdoors in temperate climates.

Dutch outdoor cannabis strains have been selectively bred over many generations to withstand outdoor cultivation at Dutch latitudes.

When to start indoor cannabis seeds?

It’s up to you! The beauty of indoor cannabis seeds is that you create the optimised grow environment indoors. So long as good indoor grow conditions are maintained you can grow your indoor cannabis seeds at any time of the year, or even all year round!

What do you need for indoor cannabis seeds growing?

You need grow lights, a carbon filter, extraction fans, a grow medium/grow system, nutrients and a few other devices perhaps (thermometer, humidity meter, pH meter). You can buy the equipment easily online or in a grow shop. You will also need some quality cannabis seeds from a proven supplier!

What is the average flowering time of indoor cannabis strains?

Typically around 8-10 weeks bloom time for indoor feminised cannabis seeds, though some Haze strains can take up to 14 weeks. Autoflower seeds grow from seed to harvest in around 10-11 weeks.

What is the average yield of indoor cannabis seeds?

There are so many factors that it’s hard to give an average yield. Light type, grow method, skill level, cannabis genetics all have a huge impact. Many growers aim for around 75g-100g per indoor plant. But inexperienced growers may get less, and professional growers could get much more.
