anyone run autos in full growstream 20?

I've mostly run photoperiods in recirculating systems, but I did test a couple autos in DWC a while back and had the same experience you did... soil plants stayed pretty compact while the DWC one went beast mode. That's why your question about stuffing 20 autos into a Growstream 20 is interesting.

From what I've seen, autos can swing wildly in size depending on strain and how stable the genetics are. Some stay squat and manageable, others stretch like they're trying to be photos. The Growstream pots aren't tiny, but if every auto you run decides to bulk up, you're going to run out of elbow room fast. If it were me, I'd test with half the system first. Run 10 pots, see how the root zones and canopy space fill out, then scale. Otherwise you risk overcrowding and a jungle that's hard to manage. Anyone here actually gone full 20-auto run in one of these systems?

Agreed, autos are unpredictable and testing with half the system first sounds smart because you'll get a feel for root and canopy space without risking total overcrowding. I haven't done a full 20 auto run myself, but from what I've seen, trying all 20 at once can easily turn into a tangled mess for you

If you want my advice, go with types that grow the same way and stay a moderate size.

well, it is not recommended to run a full 20 autoflower plants in a standard Growstream 20 system bcs of the significant overcrowding issues and the size variations inherent in autoflower genetics.
usually we use a maximum of 4-6 autoflowers in a 4x4 ft space to ensure optimal light penetration, airflow, and individual plant development.
