coco vs ...

I'm planning for my new grow place. I'm fairly experienced with coco. Is there any reason why I should consider aero / fog / ebb&flow? I mean it's all hydroponics.. is it worth it deviating?

I don't even have a drain I just feed low 600 ppm to 700ppm for me never had problems and when they did I just had to back them back with a little of regular water and they'll be just fine I just have a res I fill with 30 gals and hand water will I think the pot wont hold anymore I barely have any runoff

I have a few strains that do better in coco then rdwc,find the right strain and rdwc will out do coco but not by much.rdwc is less work as long as res is outside the room.My next grow will have a mix of coco/rdwc.Im finding the rdwc plants can take a higher ppm then coco.

I'm limited to a tent, so nothing can get out the tent
I'm planning for a new grow room and considering should I stick to the old & tried method or try smth new

Stick with what you do well.....

Why don't you ebb and flow with coco? One res change a week and auto feeds 2 or 3 times per day. I have had five footers in 2g cloth pots flooding 3 times per day and loving it. Add water midweek.

How about flood and drain with no medium? Use a tray cover with holes for small net pots.

Flood and drain is the most forgiving hydro method and with no medium there is no potential for salt buildups. Otherwise I would consider hydroton in flood and drain.
