Cannabis Seeds: Buy Marijuana Seeds Online

Which type of cannabis seed is right for you?

The most important step when you buy weed seeds is choosing the type: it decides how the plant is grown, how long it takes and how much it yields.

Cannabis seeds for outdoor growing: UK, Europe, USA and Canada

Outdoors, the right seed depends above all on how long your season is — the plant has to ripen before the autumn rain and the first cold nights:

• Short seasons (the UK, Ireland, northern Europe, Canada and the northern US): choose early-finishing feminized strains such as Northern Lights (1st week of September), Wembley or Kryptonite (1st–2nd week of September). In damp climates Black Cherry Punch is a strong choice: it is mould-resistant and finishes in September.
• Long seasons (southern Europe, California, the US South and Southwest): almost any feminized strain finishes outdoors, even late sativas such as Amnesia Gold (2nd–3rd week of October), and big producers reach their full size.
• Autoflowering seeds: go from seed to harvest in about 43–80 days, regardless of day length. They allow two harvests a season and finish before the autumn rain — the safest choice for short summers.
• Fast version: photoperiod strains that finish one to two weeks earlier, between late August and mid-September.
