Passion #1, fully proven 1980’s high THC Californian Indica genetics

Passion #1 is one of Dutch Passion’s most potent ‘green’ outdoor varieties with THC levels around and sometimes above 20%. She isn’t quite as cold-climate friendly as Frisian Dew and therefore tends not to be recommended to growers with cooler, grey climates.

But with moderate warmth and some sun you can expect premium quality buds and huge plants. The plants can grow to large proportions, easily 3m/10ft tall with XXL harvests of notably high-quality buds with a spicy, tart citrus aroma of lemon & lime.

Like the other outdoor strains mentioned, she also excels in a greenhouse or polytunnel. An exceptional outdoor cannabis seed variety with high-end potency and massive multi-Kg yield potential.

If you’re looking for a specialist outdoor-bred feminised seed variety with exceptional resilience and XL yields then Pamir Gold is the strain for you!

Bonus Pick: Black Lebanon from the Super Sativa Seed Club

Black Lebanon is a first-rate bonus recommendation to those that love rich, old-school hashy flavours and aromas with their outdoor weed.

She comes from Dutch Passion’s sister seed company the Super Sativa Seed Club, an original 1980’s Dutch Seedbank with their own extensive genetic archives.

Black Lebanon is an original 1980’s Hash Plant, made by crossing Lebanon #2 with Lebanon #5. She is a powerful indica with tasty buds that have the flavour of berries alongside fruit & earthy notes on a powerfully flavoured hash background. Deeply pleasurable lay-down indica effects come as standard, with heavy outdoor yields.

Outdoors she is ready to harvest in early/mid-October in the northern hemisphere (early/mid April in southern hemisphere). So she does best in a climate with reasonable outdoor grow conditions in early autumn/fall.

Extra tips and recommendations for a successful outdoor harvest

Selecting the toughest outdoor strains that will yield well in your conditions is only part of the challenge. The other is to provide a sunny outdoor grow location with good quality, nutrient-rich earth. You have the choice of rooting your plants directly into the ground or planting them in containers. Container-grown plants have the advantage of transportability in the event of extreme heat/storms. But may require more frequent feeding and supplemental watering in hot weather.

Local soil can be improved with new grow-shop soil and/or amended with additives - bat guano, fish/blood/bone meal, dolomite earth (Calcium/Magnesium rich mineral), well-rotted manure, compost etc to improve your final harvest quality/quantity.

Many outdoor growers germinate their cannabis seeds indoors under 20/24-hour light for a few weeks before planting their seedlings outdoors once the weather has warmed up sufficiently.

This allows your plants protection from the elements, slugs, snails & predators while they are young and at their most vulnerable. Indoor germination & initial growth also allows your plants a head-start and a few more weeks of valuable development under optimum conditions. This could eventually lead to larger plants and heavier final yields.

Many outdoor growers & guerrilla growers routinely plant a few autoflower seeds outdoors alongside their traditional photoperiod feminised strains. This offers the grower some autoflower buds to harvest in mid-summer.

Top-10 tips for growing autoflower seeds outdoors.
