Planning a 3000 watt Sour Diesel grow, switching from SunShine#4 (hand watering) to a EBB and flow type system. Have a few questions from people who have done ebb and flow.

I am going to use Hydro Rocks (expanding clay) but I am a bit unsure of what size pots to use right now. I currently use 3 gallon pots for my project, but I am guessing that is over-kill with ebb and flow. The weight of the hydro rocks alone would be pretty heavy for a table wouldn't it? Would two gallon pots be enough or does one gallon even work? I have friends who do NFT in tiny little containers with hydro rocks, but that's kind of comparing apples to oranges isn't it? I plan to veg for about 1.5 weeks, but keep in mind the diesel grows pretty darn tall...I know with most mediums you need a gallon per foot of growth, but this doesn't apply to hydro right?

Second question, I don't like trays because it makes it very difficult to move plants around, kind of like playing one of those games where you need to slide the little pieces out by finding the perfect combination of pieces to move in order to get it out. What can be used as an alternative? I am not super familiar with ebb and flow, but I know that the plants have to be suspended in air off the table so that the roots aren't jammed into the table. I was thinking just cut a few holes in the table and place metal rods in it to suspecd the plants...does that work or am I not thinking of an easier method?

the table have a expansion kit that you put on top with holes on them so you can suspend the plant.

answering your first q. the table is very sturdy clay pellets are light. You just have to make sure you flood enough water in it so that theres enough water getting into the medium.

sorry i didn't answer everything i got lost because you put like 5 question into one sentence. but hope that helps lol

Oh cool, didn't know they came with expansion kits to hold the plants. Pretty cool idea.

No, ebb & flow systems don't need the plants to be suspended. It's better described as flood and drain. And large particle aggregate (grow rocks, hydroton, clay balls) is the best thing to use for it. You want the medium to be flooded to about 3/4 its height.

For 1.5 weeks veg time, a six-inch pot will work well. Putting each plant in its own pot will allow you to move them around during growth. If you have extra room in the bed, you can fill it with spacers so less solution is needed to flood.

So the pots just sit on the table and that's it with a flood and drain? Don't the work gets fucked up being pressed against the table? Please explain

P.S So does that mean I should put as many six inch pots as I can fit into my 4X4 table or space em out? Sorry, super new to flood and drain.

A flood and drain system is a container that has plants in it, and the container is filled with nute solution to feed the plants. Is that what you want me to explain?

It's easiest to buy the flood container, a ready-made hydro bed. They are black molded plastic, and have drainage channels so the pots don't sit in still water.

Yep I got it now. I was just confused weather or not the plants sat in a tray on top of the flood table that's all. Thanks for da info.

I have an ebb and flow 4x4 table and love it.
the cool thing is you can use 4x4x4 rockwool blocks and you dont even need a pot at all. I am trying to use both.
You can use a smaller set of trays inside the table so you can keep track of your harvest dates.
You just harvest one basket a week.

i turned my 2x3 table into a aero setup by buying the expansion kit that fits on top.
