Lets talk a little bit about autoflowering cannabis, and how to grow it without nutrients to avoid that horrible burn and possible decrease in yields. These girls are modified to stay small and compact, jump starting themselves directly into the flowering stage. Ultimately these cannabis plants are very fragile, and in no way need anywhere close to the amount of nutrients a full size photosynthesis plant would need. So you need to keep your idea of an aggressive nutrient plan at bay and possibly think of an organic option.
We have a few suggestions that can help along the way if your interested in adding autoflowering cannabis to your collection.
Autoflowering Super Soil
This is the idea of having a one step solution for growing autoflowering plants. You essentially just monitor your pH levels in the water your using and give your cannabis plant just that water alone. The super soil naturally includes all of the essentials you are going to need throughout the life cycle of your autoflowering plant which totally wipes out the need for synthetic nutrients or additives.
You have two options when choosing your super soil, or one step soil. You can either make it your self with the different components and ingredients to save money, or simply buy a premade mix which takes out any guess work and allows you to plug and play. You can experiment with both options to really dial in your cannabis grow, after all every strain is different and when you really figure out what it is that cannabis plant wants she can be very rewarding in sense of yield.
We recommend researching Subcool's Super Soil recipe if you are interested in making your own cannabis soil. This method is better suited for experienced growers who understand the different NPK ratios, this will help with mixing and customizing the super soil to your specific needs.
