Btw...should I have dwarf auto flowering plants on a 20/4 light cycle ? Anyone?
You're going to hear mixed views on this especially since it's an auto. Because it is an auto people will say it doesn't matter and that 20/4, 18/6, or 12/12 will be fine from veg to flower. I mean that's why autos were made in the first place; people wanted a plant that automatically flowered without having to change the light cycle.
In my grow, I actually treated it as if it was just another plant and went 20/4. No reason behind it nor no real hard data that it's going to affect my end yield, I simply just felt like doing so.
Now... from my understanding, in general, plants use light cycles for various development. They use daylight for photosynthesis and at night through various complex cycles, breakdown stored energy, distribute, and uptake nutrients. With this it only made sense to me that even though it's an autoflower giving it some night and daylight would still help the plant regardless if it's an auto or not (especially in flowering when I'm using nutes).
In the end she's going to be your little girl and you'll have to be the one making the decisions
just want to help by dropping some thought to your question instead of just a solid yes/no, 20/4, 18/6, 24/0 answer. Either way I'm subbed and can't wait to see this thing take off.
