Questions Add an Auto to a Flipped Photo Grow?

Although I have a lot of experience with gardening generally, I still have a lot to learn about growing cannabis indoors, which brings me to my question. Can I add an auto sprout to my photo-grow when I flip to 12/12 for flowering? I have a single, small grow space, and would like to maximize the grow. I have the space for another plant. Autos can grow on the 12/12 cycle and mature, right? Am I correct that some do this with autos in micro grows?  Thanks in advance!

Yes, you can do that and that is a common practice for some growers. Just be aware that because you are reducing the amount of energy that the plants can get, the yield will be a little lower than a plant grown with longer light hours.

@Monkeydo Excellent -- I thought reduced harvest would likely be the only downside.  Thanks!

One thing you may want to consider is humidity, seedlings and young plants like high humidity which is not what you want for late flowering. Higher humidity in flowering stage can bring on powdery mildew or worse yet the dreaded botrytis (bud rot).

Yes, thanks!  I am hoping to time them so there is a huge overlap in flowering, but you raise an excellent point.


Don't forget light intensity. Young ones won't like the flowering light. Most flower tents get pretty full too, so space might come into play.

So yes. Technically you can do auto's like that but the environment would not be ideal. That would show up in the end.

Thanks!  I am able to manage the light intensity issue, and I think I have the space, which I don't want to go to waste.  Time will tell, and it could get interesting.
