male autoflower

The number one fear any beginner grower has when working with regular sex seedlings is to allow a male to pollinate the entire crop. There is no need to be concerned if your intention is to pheno hunt all the female plants, as removing males before they produce sacs will cause no need for concern.

Sexing cannabis plants is really just finding out whether they are male or female, this can be very important for various reasons, ranging from a breeding project to extensive phenotype hunting. Knowing how and when to tell if your plants are male or female will give you an advantage when growing indoors.

2. Male Plant Characteristics

The only sure way to determine sex before your plants reach maturity is to c lone the plant. T his could be achieved by taking a clone from any plant.

• Large scale Sea of Green operations can be set up, without the need to worry about any male plants. This means the crop will not be cross-contaminated with pollen and become seeded and commercial useless.

When growing from seed, Cannabis plants will spend the earliest stage of their life cycle focusing on the root, leaf, and stem production.

To minimize the negative effects of transplanting, remember the following tips:

Some sativa varieties on the other hand, like an autoflowering Amnesia Haze, might respond really well to topping. These plants can easily reach over 150cm and usually respond well to topping, especially during the early stages of vigorous vegetation, allowing for multiple colas and even light dispersion across the top of the plant.


It is true, that all autoflowering strains contain ruderalis genetics, as that is what gives them the autoflowering trait. And it is also true, that Cannabis ruderalis varieties generally contain higher concentrations of CBD than THC.

Some growers swear by topping their autoflowers, arguing that it creates more colas per plant and ultimately increases their yields. Others argue that, with such a short lifetime, the time it takes for plants to recover from topping actually decreases their yields.

This myth isn’t entirely true and depends a lot on the individual strain you’re growing.

I believe the Kinks said it best:

I’ve read a little about it – something about F2s and F4s – but most of it is over my head – ha ha!

What I have gleaned is that feminized seeds are often a little unstable (which may be why many of the most experienced growers plant unfemed seeds, and cull the males) – and can become hermaphrodites with or without stress factors (temp, humidity, transplant, nutrient deficiency/toxicity).


The Hobbit I currently have underway also produced pollen sacks – low down on his/her stem that I didn’t notice under the fan leaves until after they had opened and dropped their payload.

Anyway – I’m sure someone that knows what their talking about will chime in here – but in summation, from what I’ve read, feminized seeds are just a little unstable like that.

There are some very experienced breeders on this site that can tell you why feminized cannabis seeds sometimes become hermaphrodites (and I’m assuming by week 4 that your plant has produced pistels at the bud sites?).

As she was the only plant I had in flower – I kept on with her, and she produced three seeds (that I can see) on her bud sites.
