growing autoflower marijuana

It goes without saying that seedlings don’t require nutrients. If you’re going soilless, a mild nutrient solution is fine, but don’t go above 150–200 ppm to avoid burning them.

Whether you Top, FIM, or LST the plants, autoflowers will perform well. However, training techniques must be employed only on healthy plants so the plant has time to recover from the initial stress. Unhealthy plants cannot be trained since there’s no time when it comes to autos.

It’s also important to do some research to purchase autoflowering seeds of the highest quality. You can do everything right but it may all be for naught if the strains aren’t meant to produce high yields. For example, Fastbuds catalog shows you seeds ranging from XXL to L yield category, and you can choose anything depending on the space available.

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.

If you’re unsure of any of these questions, you’re not yet ready to sow autoflowering seeds. Other types of plants allow you to plan things after sowing seeds, but for the love of God, don’t try that with autoflowers. The minute you soak seeds in the water, the clock starts ticking, so think through everything including the medium, container, ventilation, lighting, grow room and space before planting anything.

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.

It’s also critical to transplant only after the roots have filled out in the container since the soil will drop off in clumps with the roots stuck to them. In other words, wait until the plant is a little root bound. Since there are so many conditions, it’s best to start directly in the final containers. With no disturbance, you’re all set to get great yields.

Another drawback to clones is they can take on negative traits from the mother plant as well. If the mother has a disease, attracts pests, or grows weak branches, its clones will probably have the same issues.

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.

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.

Most experienced or commercial growers will not use feminized seeds because they only contain one set of genes, and these should never be used for breeding purposes. However, a lot of beginning growers start with feminized seeds because they eliminate the worry of having to deal with male plants.
