Hello everyone... I am about to enter flowering st...

12/12 won't be good for your autos and your photo periods won't flower at 18/6. Best if you only one grow space, to grow only autos or only photo period plants at any one time. They have totally different lighting requirements and trying to grow both types in the same tent will produce complications, with one or the other suffering. Hope this helps,..... Organoman.

They would be getting the wrong end of the spectrum. If you have an option to use both spectrums simultaneously, that would work. You would need to have some kind of stand to get the babies close enough to the light once your other plant stretches. If this is possible, you can definitely start some new ones without much problem.

Ideally plants have to be of the same age, provided that you have sufficient room and light to raise two contemporary plants Those who raise more than 1 have a veg-only grow tent and a flower-only grow tent.
