Males will have round balls—these will develop into pollen sacs, which will release pollen into the air when mature.
Cannabis can be either male or female—also called “dioecious”—but only females produce the buds we all know and love. For reproduction, males have pollen sacs and pollinate females, causing female flowers to produce seeds.
These are referred to as “bagseeds” and whether or not you can grow one will depend on where it came from.

Cultivating males is important for breeders trying to cross new strains and genetics, but most people growing for buds will want to remove the males.
Even if your seed sprouts fast and grows vigorously, it still has roughly a 50/50 chance of being female and producing buds, instead of turning out to be a male.
Some seeds germinate very rapidly while others can take a while, but generally, seeds should germinate in 3-10 days. If it’s been two weeks and a seed hasn’t sprouted, it’s probably a dud and won’t sprout.
Marijuana seeds can be acquired from an array of sources and can vary in quality. For more info on how to buy marijuana seeds, check out our Guide to buying cannabis seeds.
In particular, full-spectrum LEDs work the best for any type of autoflower. The higher the lumens, the better the yields, but if you cannot afford expensive lighting equipment, CFLs will work well during the vegetative phase.
Most people assume that autoflowers produce small yields, but they can’t be further from the truth. Get this straight — autoflowers can not only produce humongous yields, but the fact that they do so within 2 months isn’t a small feat! But, you gotta follow a small rulebook, so here are 7 tips and tricks to maximize yields in autoflowers if you’re struggling to get the best out of them.
7) Use proper training techniques
Autoflowers grow even when they get only 12 hours of light from seed to harvest. They are tough and adapt in any situation; however, they thrive when they receive 18 hours of light and 6 hours of darkness. Some growers provide 24 hours of light from the beginning until harvest, but it’s not recommended because plants need some rest and time to recover like the rest of us.
Most autoflowers start flowering in the third or fourth week, so start training only if the plants grow fast and remain healthy enough to be trained. If you’re unsure, it’s okay to not train the plants at all.
5) Keep an eye on the pH
It’s common for beginners to load their plants with too many nutrients and burn them. We get that you love your plants, but you’re only harming your autoflowers by feeding extra nutes. Photoperiod plants have bigger roots, but autoflowers are comparatively smaller and the nutrients have to be adjusted accordingly.
Here’s a quick table to help you understand pH better:
Now that you know the basics and what to avoid, you’re all set up to start your first autoflower indoor grow.
Frost must be avoided at all costs. Typically, most growers begin planting when spring is just around the corner. Depending on where you live, you can plant the seeds as soon as the frost clears. If you reside in a location that doesn’t receive any snow, go ahead and plant when the temperatures range between 22°C to 28°C (71°F to 77°F).
7. Over and under-watering
After all, a plant that gives you lip-smacking buds in just 2 months deserves some research, eh? Autoflowers may scare you at first, but if you avoid a few common mistakes, you’ll harvest much more than you can imagine, and it only gets better.
Autoflowers (aka self flowering seeds) are suited for beginner growers but it’s crucial you know the basics if you want to have a successful harvest the first time you grow cannabis, although you can learn as you go, it can be disappointing if you waste time and money, and end up with nothing to smoke.
Talking about nutrients, some growers try to make their own nutes. While it’s completely okay to do so, you should avoid doing it if you’ve never done that before. Nutrients are expensive and it’s tempting to make your own, but try to attempt that after you’ve gained some experience.
Often referred to as popcorn buds, the lower portions stay small. However, harvesting the main colas and leaving the popcorn buds on the plant for a week more will increase yields dramatically. Be patient, and let Mother Nature do the rest for you! If you avoid these common mistakes when growing autoflowering cannabis, you’ll soon be rewarded with potent resinous buds that will last a long time if stored properly.
