Dwarf low flyer x2

So I'm thinking of doing a few small grows just to keep mms supplied with smoke over the winter and I'm really liking the idea of a dwarf low flyer on gets to be about 2 feet tall and there an auto flower fem seed from cropkings. So my question is can I put both plants when they are rooted into separate Rockwell cubes and then into the same 4 inch net pot that's on top of my 5 gallon dwc, I just don't want to have to use 2 buckets I'm limited on space. Also I would be using an lst method pulling each plant away from each other.

Yes you can.

However i would suggest just one plant per netpot. Look into mainlining, you'll get a similar effect as 2 or 4 plants.

I've decided to use a crown royal fem seed and just do a lot of training on it where should my water level go i have a 10inch net pot 6 inch square rockwool cube and the rest is clay pellets . Should my water level be just at the bottom of the net pot of a bit above the bottom ? also will the rockwool pull water up so the seed gets enough moisture?

This is my set up I'm runing a 150watt hps, I'm using Substra Vega A,B

I never had much luck with rockwool so i'm not the guy to ask.

In my experience it doesn't like getting too dry or too wet.

I use collars and hydroton and keep the water an inch below.

Bump!
