What do you guys think of this, and is 9 plants possible from this system?
ebb and flow

Yeah it looks good to me. Looks like your plant sizes will be small in that setup though.

I read your grow journal too BTW and I am sorry that things went badly.

FYI a PH tester is key to a successful grow. With the wrong PH your plants may or may not be able to absorb the right nutrients or any nutrients at all.

I have to monitor mine daily. I fucking hate it but it has to be done!

You can see all of my trials and tribulations here:

Newb growing for GOLD!

I am using a lot of hi-tech equipment and have even added more since (like a much needed PPM meter).

Once I get my plants into flowering my next big thing is to get a good CO2 solution.

Peace!

expensive is the first thought that comes to mind

dude, In my opinion, if you are gonna go with ebb and flow you should reap all the benefits that come with using that system. I don't like those systems because, like an aeroponics system you are restricted on where you can put your plants and how man plants you can have. By using a tray, you can freely move the plants around and if you wanna add an extra plant or two you can .
For that amount of money you can put something together yourself, with great ease.
