Feminised CBD Seeds

Feminised CBD seeds give CBD-rich photoperiod plants that are almost all female: they keep growing while you give them long days of light and flower when you switch to 12/12. Of all CBD seeds, they're the ones that give the biggest plants and harvests. We have 13, from balanced profiles close to 1:1 to strains with THC below 1% according to their product page, such as Swiss Chocolate CBD or Critical CBG. They all cost the same: from €3 per seed in the pack of 25. Below you'll find the flowering time, height and yield of each one.

There are 13 products.

What's special about feminised CBD seeds?

You decide when they flower. A feminised CBD plant keeps growing while it gets long hours of light and only flowers with 12 hours of darkness. That lets you control its size indoors and take cuttings from the plant you like best, and outdoors the plants can grow big and very productive.

Because they're feminised, almost every seed gives a female plant, and females are the ones that form buds. Indoors, the moment you switch to flowering sets the final height: the Critical Green CBD product page advises doing it at around 30 cm if you're not going to train the plant, and the Grapefruit CBD page says not to go beyond 4 weeks of vegetative growth if you're not going to prune, because it stretches a lot in flower. If you find a plant whose profile you like, its cuttings are genetically identical: the White Caramel CBD page suggests exactly that, a good mother plant and SOG grows.

The trade-off is a longer cycle than an autoflower: on top of the weeks of vegetative growth come 7 to 11 weeks of flowering. If you'd rather have speed and a small plant, have a look at our CBD autoflower seeds. And if you want to understand THC:CBD ratios or see the THC and CBD of all 19 strains side by side, it's all in our CBD seeds guide.

"Not stated" means the product page doesn't give the figure. For Critical Green, White Caramel and Swiss Chocolate CBD, the indoor yield is under a 300–350 W LED; yours will depend on your light, your space and the weeks of vegetative growth. The other three feminised CBD strains in our catalogue, CBD Therapy, Harlequin CBD and Jack Herer x Black Domina CBD, are sold out right now.

Indoors or outdoors? Which feminised CBD strain to choose for your grow

For an indoor grow tent, look for plants that don't stretch much, such as Himalaya Gold CBD or Critical Mass CBD. Outdoors, where autumn turns wet early, go for the September harvesters, such as Critical CBG or Critical Green CBD. And if you have sun and space, Amnesia, Swiss Chocolate or Critical Green CBD grow into 2.5–3 metre plants.

Indoors

Himalaya Gold CBD Stays between 90 and 120 cm indoors and responds well to training.
Critical Mass CBD Is short to medium in height, with thick colas that may need support towards the end.
White Caramel CBD Stretches little indoors, and its product page recommends it for SOG with small cuttings.
Grapefruit CBD Stretches a lot after the switch to 12/12 and smells even in veg: you'll need good odour control.

Outdoors

If autumn arrives early and wet, Critical CBG is harvested in mid-September, and Critical Green CBD between mid and late September.
If your climate is warm and dry, Amnesia CBD and Grapefruit CBD finish in mid-October; the Amnesia page recommends a greenhouse where autumn comes early.
Watch the humidity with the densest buds: the product pages of Critical Mass CBD, Critical CBG and Critical Green CBD warn of the risk of mould or botrytis in damp conditions.

Feminised CBD seeds FAQ

Do feminised CBD seeds always give female plants?

Almost always: they're selected so that practically every plant is female, and females are the ones that form buds. Even so, check your plants at the start of flowering, as you would in any grow.

Which feminised CBD strain has the least THC?

According to its product page, Critical CBG, with 0.05–0.1% THC, although it's rich in CBG, not CBD. Among the CBD-rich ones, Swiss Chocolate CBD, with 0.20–0.25% THC and around 15% CBD.

Which one yields the most?

Indoors, Critical CBG (550–750 g/m²) and Critical Green CBD (600 g/m²). Outdoors, Amnesia CBD, which can top 1,000 g per plant, and Critical Green CBD, which reaches a kilo on the biggest plants.

When should I switch a feminised CBD plant to flowering indoors?

It depends on your space and the strain. The Critical Green CBD product page advises doing it at around 30 cm if you're not going to train the plant, and the Grapefruit CBD page says not to go beyond 4 weeks of vegetative growth if you're not going to prune, because it stretches a lot in flower.

How much do feminised CBD seeds cost?

Between €3.00 and €4.33 per seed, depending on the pack: €13 for 3, €19 for 5, €33 for 10 and €75 for 25. All 13 are the same price.
