I would recommend soft pots, Jason the ceo has done millions of pots all around the world and if your looking for max yeilds and don’t mind cleaning the soft pots (I just got double so I’m not rushed) then fabric will give you a bit of a boost…
The new 5 valves and lines come with every setup so no stress there.
I like having 25 gallons minimum for 4 plants.
Run your pro mix and then switch later like you said no sweat.
If you want bigger yeilds possibly you can run an air pump and air domes with their line or a air stone in the bottom of the pot many have good luck with the air stones. You don’t need clay pebbles in the bottom but do they help and do air stones/domes help? That is up for debate in fabric it does help in plastic.
Personally I wouldn’t go with plastic but it will still grow fine.
It comes down to tuning your setup you have, both @Not2SureYet and @Myfriendis410 arnt getting the same yeild as they are from top watering but again still early on and running mostly plastics with air. I think @Not2SureYet is starting to run some fabric pots but other variables have changed like nutrients and Alan just moved.
My suggestion is go with fabric and if you want to spend more get the air domes and run. Them to see if it’s worth it fid yku do 50/50.
I would rather run 5 plants that are super easy to keep then 3 or 4 that produce maybe more which are more hassle,give me more real garden time less work. Or I use that time to chill more lol.
As for jacks I know it works and it can work really well I dont personally have a experince to say it’s better than this or that. I run chemgro and am trying to do a chemgro vs Jack’s but can’t get my Jack’s seedlings to survive haha. Just bad luck and haste on my part with changing variables
