Only Heavyweight would attempt to improve upon perfection, but they have, somehow, managed it. The yields are gargantuan, the flowering time is breathtaking, and the flavours are even more mouth-watering than the original. A truly remarkable plant.

This indica-dominant Skunk/Kush cross stinks superbly of rich, pungent cheese and hits as hard as any generic Cheese strain on the market. It is a genetic masterclass and pretty much the last word in relaxation. Welcome to a world of calm.

Heavyweight have a gift for apt, accurate ways of naming their strains, and no nomenclature can be more accurate than Fast & Vast. It's simple, really. A rapid flowering time and brilliant, heavy yields (a good gardener could reap 800 g/m2 indoors) have ensured permanent popularity and a fantastic, well-deserved reputation. Our hats are off.

This is a punchy, fruity, powerful and highly productive plant. An experienced grower is looking at anything up to one kilo per plant (outdoor yield) and the 22% THCs are enough to please even the most seasoned of smokers. This is a lot of bang for your buck.

The beginners guide to sativa-dominant autos is here, in the form of Heavyweight's delicious Fruit Punch. This is a sweet-tasting, resinous and extremely social strain, promoting lively, affable conversation and deep, thoughtful discussion. It is extremely easy to grow and, with yields approaching 800 g/m2 when grown indoors, has proven one of the most popular autos of our entire site.

A cross of auto Big Bud and auto White Dwarf, this plant delivers vast quantities of tasty bud before most other plants have even taken root. The mind-numbing couch-lock can be avoided with a tempered toke, but the plant is versatile enough to be enjoyed by smokers and gardeners of all levels. A truly remarkable and brilliant value-for-money strain.

With an 8 week flowering time and a height no taller than 80cm - one could be forgiven for not expecting much in the way of yield. The Massive Midget, as the name might imply, has other ideas. Indoor yields can deliver a hugely satisfying 450 g/m2, and the quality of the bud is absolutely brilliant. Tasty, aromatic and reassuringly potent.

The Money Bush has obvious commercial applications on account of her outstanding yields, but, surprisingly, this has come at absolutely no expense in terms of flavour, smell or potency. Heavyweight have really hit the bullseye with this strain and there are few that can offer so much bud in so little time. Nature at her finest.

Heavyweight think their Kush is superb and we have heard nothing to dispute the fact. The sour, fuelly aromas mean mouths water during every minute of flowering, and the high this plant delivers is easily worth the admission fee alone. No plant has done more to spread the fame of OG Kush than this brilliant offering from Heavyweight Seeds.

Heavyweight Seeds Cannabis Seeds; Head-spinning indicas, soaring sativas and an ongoing quest for excellence.

Heavyweight Seeds has an expert team dedicated to the research and development of superb-quality strains. Its goal is to produce high-quality genetics and their breeders will not stop in their quest for perfection.

Heavyweight Seeds currently produces an exciting and varied range of feminized cannabis seeds with types for all tastes, from medicinal to psychoactive. The super-productivity of the Heavyweight range also makes them a perfect choice for the commercial grower.

Massive yields and knockout highs, the gloves are well and truly off.

There was a time when autoflowering cannabis strains represented a poor and unstable genetic and low productivity, but this ended the moment cheap Heavyweight seeds entered the market. Their autoflowering weed seeds are completely stable and are a great choice for the novice or for the grower with limited growing space.

Heavyweight Seeds has become synonymous with top-quality seeds and high-yielding plants since entering the ring in 2010. Bob and weave your way through the hard-hitting indicas and swinging sativas of a vibrant, dynamic catalogue, full of energy and life. Some of you may plump for power, some for productivity, but each one of these strains is a heavyweight champion in its own right and will never throw in the towel.
