Help With Ebb & Flow Flood (Grow) Tray

For an "Ebb & Flow" flood tray, I'm looking at a 3'x3' American Hydroponics heavy duty white flood (grow) tray. However, it's only 4 inches deep. Is that deep enough for "Ebb & Flow" flooding? I plan to use it for SOG grows where the height of the plants will NOT exceed 3 feet.

yea thats fine, you want the water to come up a little higher than half the pots. the hydroton might float away if you submerge the pots to much. just make sure you hand water until you are sure some roots are getting wet from the floods.

I personally want to see the tray at least 6" deep.

That way I have options.

My flood return drain has two adaptors...one to drain at 3" the othe at 5 1/2"....so I can drain at whatever water level I please.

If your Hydroton is floating away.....you add more Hydroton.

I think deeper is better.

This is my setup, if it helps.

Botanicare 3x3 table

Veg: 3 inch netted pots (see flood line)
Flower: 6x6x6 square pots (see flood line)

I think deeper is always better

go to home depot and get a cement mixing tray!!! work great

go to www.greners .com they have 3x3botanicare tubs reasonably priced that are 7'' deep although i think the 3'' deep one would work

thats what she said last night

Yea I use the home depot cement mixing tray, too.


But I'm digging your homemade tray. I was always scared to build one like that because of potential leaks in the vinyl...

I'd try to get a deeper tray if I were you. like 3'x3'x7"

plywood base and sides. 2x4 legs, 40 mill pvc material to make waterproof.... http://www.simplyplumbing.com/oatey-41597.html they sell it at home depot and lowes. VERY heavy duty stuff. The sell buy the roll. Figure about $20 for a 5' long and 4' wide table. That table took about 40 minutes to build and is EXACTLY the size I wanted it. its 2.5 by 5.5 feet long and I'm going to tr5ain my plants out from it through a 3.5' x 7' scrog screen.
Cheers

I did the same. I made a plywood and 2 x 4 table that is 4' by 12' with 4" sides. Offset at an angle so it all drains to one edge and towards the far corner. I use a strip of plastic gutter to catch all the runoff and direct it to the reservoir. I lined the table with panda film and stapled it all the edges and over the lip of gutter.

Not to hijack the man's thread, but I'm currently in the process of designing tables and collecting supplies so that I can have everything ready by my 11/1 deadline to be ready to rock and roll. I spent countless hours on this website and others tryin to learn as much as possible from other peoples trial and tribulations and I have really enjoyed seeing yall post pictures of your flood tables. Can I see more? Most people on this website do DWC or aeroponics drip, or and eb and flow with a control bucket. I want to do flood tables and I like your styles and I want more. Especially you quiller, I've never seen a table like that before can I learn more about yours, do you have no sidewall and all the water just goes straight to the table onto the gutter then circulates through the reservoir? I'm intrigued and confused.

There are sides on the table, about 3" high. Then wrapped and stapled with plastic. I wanted more space than a standard 4 x 8 tray so I built my own 4x12.
