Auto Weed Seeds FAQs
How are autoflowering seeds different from regular seeds?
As the name suggests, autoflowering seeds will bloom on their own, whereas regular seeds require more encouragement.
Typically, to get regular seeds to bloom you need to alter their light schedule at a certain time. This requires keeping tabs on where the plants are in their life cycle, as well as having the gear necessary to trigger the flowering process.
Auto seeds have a shorter growing cycle and require less space.
The autoflowering version is often hardier and less sensitive to climate changes or pests and diseases. Basically, auto seeds require much less maintenance and supervision than regular weed seeds, but they’re usually more expensive as a result.
How long does it take to go from seed to harvest with autoflower cannabis seeds?
This will vary depending on the strain, but in most cases an autoflowering version takes 8-10 weeks.
This is faster than most regular seed strains, so if you’re in a hurry then autoflowering seeds are definitely the way to go.
Do auto seeds have less THC?
In most cases, autoflower seeds have less THC content than their regular counterparts. If you want the strongest buds possible, you might need to go through the hassle of growing regular seeds.
Also, as mentioned, you’ll have to pay for the convenience that autoflowering seeds provide. Not only are the seeds themselves usually more expensive, they require more light in the beginning of their life cycle.
Be prepared to shell out for good auto seeds!
Their compact size can work against you as well. While they require less space to grow, you’ll get less of a yield than you would from a regular strain. You may be able to make up for it by harvesting more often, though.
