There are auto strains with a flowering time of just five weeks! Add in a 2-4-week vegetative stage, and you could theoretically grow a strain from seed to harvest in only seven weeks. Bubble Kush Auto, for example, is ready to collect 7-8 weeks after sprouting. Therefore, you can enjoy multiple harvests each year.
If you grow in a typical manner, you have to ensure your grow room has light-proof sealing. It is a disaster if this gets breached. In contrast, a light leakage has no discernible impact on the flowering stage of your autoflower marijuana.
There is no need to add nutrients during this period. By week three, you can begin adding nutrients and increase the feeding rate weekly. Remember, the vegetative stage is short, so you need less nitrogen. Light feeding is ideal unless you notice a nutrient deficiency. You’ll need to alter the nutrients once the plant hits the flowering stage.
After a week, opening the jars once every 2-3 days will suffice. Your bud is ready for use once there is only a small amount of moisture left. Transport your weed to a sealed container and use it within a few months.
These days, it isn’t unusual to find automatics that produce up 22 ounces per square meter.
Proper germination is pivotal to the healthy development of your autoflower marijuana plants. You can go down the traditional route of using soil, or else you can try a container with a growing medium. The paper towel method is probably the easiest way to germinate your autoflower seeds.
The shorter growing season means you have a higher level of autoflowering varieties. Imagine having the opportunity to grow five different strains in a single season! Multiple harvests are especially useful if you enjoy the growing process and are keen to sample as many marijuana types as possible.
You’ve reached the best part of this autoflower grow guide – the end. Depending on your specific strain, you may be ready for harvest anywhere from 10-12 weeks. You’ll know it’s time when most of the trichomes are whitish, and the pistils are brownish-red.
Harvest up to a pound
The downside to an autoflower grow is that the yields will not be as large as traditional seeds. However, a smaller yield on something you are nearly guaranteed to be successful at is better than no yield from something a bit harder to grow. If it’s your first time growing these quick-growing seeds, try using an autoflower grow journal to document your journey. This way, there’s a record of your work, and you can improve upon it in the future.
Week 7 – 8: Monitor and prepare
Potting mix is ideal for autoflowering seeds. Primary ingredients should include decomposed moss and compost.
At this point, your seedling has begun creating energy from its light source. If you are growing indoors, you’ll want to use LED lights to give your autoflowering plant some light. Choose LEDs – they save energy and direct less heat. Plus, they are affordable. You’ll only need a single light to grow a large plant in an indoor autoflower grow setup .
To start germinating your seeds, you will need the proper soil mixture. In general, autoflowers will need fewer nutrients than regular seeds; still, they will need rich potting soil to help support their rapid growth.
As the flowering stage proceeds, you’ll want to continue lowering the humidity if you are growing indoors yet keep your plants well-watered. It is very easy to develop mold during the flowering stage, and that can ruin all of your hard work. That’s why you need to pay attention to the amount of water in the air and soil. A watering can helps you keep track of how much you are giving your plants. We include one in our Complete Kits.
If buying from a reputable breeder or seed bank, growing from seed is the best way to ensure your plants will have solid genetics and start clean, meaning they won’t come with diseases or pests.
For the typical homegrower, it may be easier to obtain cannabis seeds rather than clones. Growing from seed can produce a stronger plant with more solid genetics.
How weed clones work
Most cannabis plants begin flowering when the amount of light they receive on a daily basis reduces. Outdoors, this happens when the sun starts setting earlier in the day as the season turns from summer to autumn. Indoor growers can control when a plant flowers by reducing the daily amount of light plants receive from 18 hours to 12 hours.
However, potency in autoflowering varieties has increased significantly since their initial introduction, with some breeders crossbreeding the low-THC ruderalis with other more potent varieties.
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.
