outdoor marijuana seeds

Silty soil is the ideal growing medium. It’s easy to work, warms quickly, holds moisture, has good drainage, and contains a lot of nutrients. The best silty soil is dark, crumbly loam—it’s fertile and probably won’t need any amending.

We also advise against using nutrients designed for indoor weed growing—they are generally composed of synthetic mineral salts and can damage soil bacteria.

The sky’s the limit with outdoor plants—you can let them get as big and tall as you want, as long as they’re manageable. One plant can potentially yield between a half-pound and full-pound of dried weed! Growing a handful of hands for yourself is more than enough. With an indoor grow, your space is a lot more restricted.

Silt soils

Typically, outdoor growers will add amendments to soil when weed plants are transplanted outside. Outdoor amendments usually come in powder form that you mix in with soil.

Soil has three basic consistencies, in various ratios:

What size pot do I need?

Balcony: This can be a great spot if it gets good light—ideally, it faces south—and will usually get good wind. However, you may need to cover your balcony from peeping neighbors.

These are just some examples of amendments commonly used in different types of soils. Heavily amended soils will have long lists that break down all organic nutrients they contain. Some companies create soils that offer a great structure with base nutrients, but allow you to fill in the gaps as you desire.

Outdoor marijuana seeds

As with all outdoor strains, growth under the cover of a greenhouse or polytunnel will protect your plants from the worst of the weather and tend to increase harvest quantities.

The large, dense blooms may need supporting to prevent them drooping down and touching the (potentially damp) ground towards the end of bloom. Harvests of 100g+ of dried buds from Auto Ultimate are not unheard of in the UK, especially when she has enjoyed an uninterrupted sunny/warm bloom period.

Auto Power Plant

Feminised outdoor cannabis seeds have the advantage of somewhat longer grow cycles and consequently heavier harvests (compared to autoflower seeds) for UK growers. The growth cycle is typically around 5 months from seed to harvest with plants typically ready for harvest around late September or early October.

Conditions, temperatures and light hours vary from one UK location to the next. The following table gives an approximate guide to the environment facing many UK growers through the summer months. Note that these are just approximate averages, each UK growing season can show surprising levels of variation from year to year and also from region to region. This presents some genuine challenges to UK outdoor growers.

Auto Think Different

As with all outdoor strains, giving the plant the benefit of a couple of weeks of indoor growth after germination helps them become better prepared for eventual outdoor life. Gradually acclimatise your outdoor plants for increasing periods of time before eventually planting them out after the last frost.
