Feminized CBD Seeds

Feminized CBD seeds give you CBD-rich photoperiod plants that are almost all female: they keep growing as long as you give them long days of light and flower when you switch to 12/12. Of all CBD seeds, these are the ones that produce the biggest plants and harvests. We carry 13, from balanced profiles close to 1:1 to strains with THC below 1% according to their product page, like Swiss Chocolate CBD or Critical CBG. They all cost the same: from $6 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 feminized CBD seeds?

You decide when they flower. A feminized 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 clones from the plant you like best, and outdoors the plants can grow big and very productive.

Because they're feminized, almost every seed gives you a female plant, and females are the ones that form buds. Indoors, the moment you flip to flowering sets the final height: the Critical Green CBD product page advises doing it at around 12 inches if you're not going to train the plant, and the Grapefruit CBD page says not to go past 4 weeks of veg if you're not going to prune, because it stretches a lot in flower. If you find a plant whose profile you like, its clones 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 veg come 7 to 11 weeks of flowering. If you'd rather have speed and a small plant, take 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 veg. The other three feminized CBD strains in our catalog, CBD Therapy, Harlequin CBD and Jack Herer x Black Domina CBD, are sold out right now.

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

For an indoor grow tent, look for plants that don't stretch much, like Himalaya Gold CBD or Critical Mass CBD. Outdoors, where fall turns wet early, as in the Pacific Northwest or the Northeast, go for the September finishers, like Critical CBG or Critical Green CBD. And if you have sun and space, Amnesia, Swiss Chocolate or Critical Green CBD grow into 8–10 foot plants.

Indoors

Himalaya Gold CBD Stays between 3 and 4 feet indoors and responds well to training.
Critical Mass CBD Is short to medium in height, with thick colas that may need support toward the end.
White Caramel CBD Stretches little indoors, and its product page recommends it for SOG with small clones.
Grapefruit CBD Stretches a lot after the flip to 12/12 and smells even in veg: you'll need good odor control.

Outdoors

If fall arrives early and wet where you live, Critical CBG is harvested in mid-September, and Critical Green CBD between mid and late September.
If your climate is warm and dry, like California's or the Southwest's, Amnesia CBD and Grapefruit CBD finish in mid-October; the Amnesia page recommends a greenhouse where fall 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 mold or bud rot in damp conditions.

Feminized CBD seeds FAQ

Do feminized 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 feminized 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 (1.8–2.5 oz/sq ft) and Critical Green CBD (2 oz/sq ft). Outdoors, Amnesia CBD, which can top 35 oz per plant, and Critical Green CBD, which reaches about 2 lb on the biggest plants.

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

It depends on your space and the strain. The Critical Green CBD product page advises doing it at around 12 inches if you're not going to train the plant, and the Grapefruit CBD page says not to go past 4 weeks of veg if you're not going to prune, because it stretches a lot in flower.

How much do feminized CBD seeds cost?

Between $6.00 and $8.67 per seed, depending on the pack: $26 for 3, $38 for 5, $66 for 10 and $150 for 25. All 13 are the same price.
