How do you expect them to express their 'dislike' as opposed to if each one was grown separately, apart from final yield that is. I'm hoping for a final yeild from all three to be equivalent to a single plant grown to cover the same area. My test will be done in 8 weeks.
Well this is a 12" pot across the top... Pineapple Gum on the left and White Widow at the back and Pink Grapefruit on the right. At 5 weeks.
You can do it in a 1/2 gal pot but you get root bound easily you will probably get an oz at most off each strain. Good luck, I wish you success. I’d rather have one plant this big then 4 trying to suffocate. That’s a Tangi took that pic a week ago same size pot it’s about 1 metre cubed week 2 of flower, should be good for 12 oz
Hi DD, yes I do agree that the secret is in the roots, it is my intuition that the plants can sense their root space and grow accordingly. With this in mind I have a system that over comes the root problem by using clay pellets which give a peculiarly good substrate structure for roots,
then the roots are allowed to emerge from the bottom into a shallow water culture of a few inches, they also have some airspace between the SWC and the pot.
. My aim for the three is to get a total of 8 zips eventually. Not sure what this crop brings if it can't make more than 3 zips I'd be surprised. I'm not expecting it but I also would not be surprised if these three produce 8 or more between them. 
Nice are you putting the 3 plants because of limited space and want multiple strains or are you doing it to see how they go?
Yes, I am happy to have gotten 18 zips because it will just see me through till the next harvest, but I'd rather have more variety. If you're running DWC you may want to rework it a bit, my first set up just used a smaller net pot but the principle of the roots coming out and sitting in a shallow pool was the same, that produced 13 zips. I'm very leery of DWC's where the roots come straight out of a small pot into the nutrient. I know people do it and it works but it's better to give the roots some substrate. But it's horses for courses, I'm after variety and boutique harvests these days.
So your doing aeroponics with extra clay balls is that what your doing looks good
I started with aeroponics, but what I'm using now is simply a normal inert substrate, plus a shallow water culture, which is like a DWC except it's only a few inches deep. So you get all the advantages of a DWC without any of the disadvantages. The main plant is sitting in the 27L of clay balls. The only air that gets to the roots apart from what gets dragged into the clay pellets, is the air gap of a few inches from the bottom of the pot to the top of the shallow pool. I think that the clay pellets are unlike any other inert substrate for this technique. The technique being to give the roots two ideal systems with each one offering redundancy.
and here's some Pink Grapefruit juice 
and some other shots of white widow juice
What do you think now the verdict is in. 12.75 zips and only about 1.5 of that is larf but it's covered in trichomes so great for juicing. Plus I achieved my goal of increasing variety and yield did not suffer. btw these are all autos.
