"Planting autoflowering genetics indoors could not be easier. There is no need to transplant them and as long as they receive more than 12 hours of light you will get spectacular results. Our team has taken the time to choose the top 10 auto to grow indoors, as well as our honorable mentions list."
Nirvana’s best autoflower strains for indoor cultivation
Growing Cannabis plants indoors allows a grower to control their environment, meaning lighting, nutrients, temperature, and humidity are in your hands. This opens the doors for autoflowering genetics to be grown using anywhere from 12-18 hours of intense lighting for the best results.
Autos are not reliant on a particular lighting regime to induce flowering, as typically associated with photoperiod cultivars. Basically, once planted from seed, the autos will vegetate for a 4-week period, before flowering automatically. With a strong resilience to pathogens, heat stress and cold temperatures, you find autos are an excellent addition to any indoor grow room.
We all know you can achieve some incredible outdoors autoflowering yields, but indoors you can really see what these autoflowering ladies can do! With such a variety of large yielding, easy to grow and low maintenance autos now available, there has never been so much to chose from! Our team recommends planting directly into a large-sized container, and to use only HID lighting.
1. Original Glue Auto
We start our top 10 list with Original Glue Auto, which is a cross of Original Glue and autoflowering genetics. A superb performer when grown indoors under HID lighting, and with a harvest date from seed to harvest of 9-10 weeks, Auto Gorilla is a must-have for any indoor grower.
