Hello guys. I’m new. And I’m thinking about autos. What medium is best for autos ? Soil or coco ? Soil+perlite or coco +perlite? How much nutes should I give ? I heared that atleast for few first weeks I should give like 1/4 of what the provider says as autos burn easy ?
Hi, and welcome to AFN. My recommendation for your first grow is to keep it simple, and stick with a single grow design. Soil works, coco works, organic works, salt nutes work, and so on. But mixing and matching often spells trouble. Choose a medium, and then study how successful growers here deal with it.
If you go with non organic, I recommend getting some MegaCrop single part nute mix, some CalMag, a cheap EC/PPM pen, an Apera pH pen (cheap is a bad idea for pH), and some coco and perlite for your medium. Read up on here how others grow with coco/perlite mix to see how to make it work. Do not try to run a coco grow with organic nutes, you will likely run into difficulty. If you go with coco, study the information on Cocoforcannabis.com before you start a grow. There is lots of good information there, and it is focused specifically on coco growing.
If you go organic, which in my opinion is likely to prove harder for your first grow, understand that organic nutes feed microbes, they don't feed the plant directly. They work slowly or bloody slowly, and you need to factor that in how you manage your soil preparation and your grow. Also understand that lots of new growers here run into issues with organic mixes that are too heavily fertilized for autoflowering cannabis. Getting an organic mix right for a first timer means fastidiously sticking to a recipe for soil that has been thoroughly proven by other growers. This can get inconvenient and expensive due to the diverse ingredients required, as well as the preparation time needed, and if you try to wing it by altering recipes, preparation, or grow technique, you may bugger your grow.
All considered, I think a coco/perlite grow with Megacrop would be your best bet for a first time grow. But you need an EC meter and a way of monitoring pH to manage a coco grow. The pH drops can work, sort of, but many people including me find them difficult to use due to the difficulty of reading the color change. I recommend a digital pen, and getting a good one like an Apera. EC pens can be cheap, but pH pens are a different animal, far more sophisticated technology, and the cheap ones usually fail early if not sooner.
As already mentioned, read, read, and then read some more. Once you decide how you would like to try a grow, there is lots of more detailed help available here if you ask for it.
Good luck with it.
