DIY Flood & Drain

I have been looking for a larger alternative... I would like to get something 4x4 myself, in a single unit and to this point have come up short in finding one.
I had almost thought about a small kiddie pool, the smallest one I found is about 5' across... a little big but.. might work LOL

yeah!
and i was thinking you could build a stand from 1"pvc for dirt cheap.
you think it would be strong enough? i have seen no info on that

1" pvc should be plenty string enough... but the pool is kinda flimsy, BUT... could either do several cross bars from PVC or a thin piece of plywood to be the table to hold up the pool. THis might actually be a good idea LOL... talk about ghetto I like it!

im building a 1" pvc stand right now and its sturdy enough for my 2x4 table. what i want to know is what power pump i will need to split my res to two seperate tables

Great thread; I'm in for this. I've been looking for a new system design today.

very cool! +rep, i'm wondering if anyone has any idea where to get a 4x4 flood table that doesnt cost an arm and a leg. unfortunately the cement mixing tubs are not large enough for what i would like to do.

i cant understand why a plastic tray should cost 150$ lol.

You can build a custom table with plywood and 2x6, here's the thread... https://www.rollitup.org/do-yourself/401668-diy-flood-table.html

I like his waterproofing

Step 4 (Water proofing your table)

In the past I used rubber or plastic sheeting or pond liners to hold in the water and keep it from leaking. But I still had a few leaks now and then. But now I coat the inside of my new tables with a liquid rubber I found called "BLUE MAX" from a company called "Ames Research". It can be ordered from them at amesresearch.com or at any paticipating Ace Hdwe store. This is a liquid rubber that is waterproof and can be applied with a roller,brush or an airless sprayer. It is non-toxic to all animals and plants and is safe enough to coat the inside of a water tank for drinking water.

TshirtNinja.. as far as the pump goes, depending on your overflow (water return pipe) depends how big a pump you need. Really anywhere from 150-300gph work very well.

My new grow using this flood & drain will start within a week, it will contain 4 THC Snow & 2 AK47 (THC Snow is a 3 way hybrid, THC Bomb, White Russian & Big Bud. It is a fast flowering 6-7 week and high yield plant) I grew 1 THC Snow in soil and it ended up at about 3 zips in a 3 gallon pot, finished in under 7 weeks.

The way to solve your setup is to use your water pump and get a extra hose to pump out that water

I like your setup there UPNSMOKE23... how many plants do you normaly put in each tub?

nice writeup, +rep for sharing

I just finished up another grow in the DIY Flood & Drain Table and absolutely love it! I grew 6 plants and yielded some 15 ounces... it should have been much more but... I had a smaller strain mixed in with 4 other plants that overshadowed them heavily, but anyways... This system works VERY well.

I do not do any leaching or flushing with this system, what I do if I feel the need to flush or leach before end of veg is remove a plant from the table and go place it in a 5g bucket with a raised bottom, let it sit there for about 10 minutes, remove and let drain and do it all over again... usually 2-3 soaks in a 30-45 minute period.

TO date have had zero issues, using Dyna-Gro products and this flood & drain.

can one of u guys tell me please , if i use one of this systems , how many times per day should i flood/drain?

depending on stage... 2-4x a day for 10-15 minutes... do all flooding during lights on.

ok , so flood for 15 min then drain , and repeat this for 2-4 times per day when lights on , thanks a lot

I just recently built some PVC rails to place around the flood & drain table, these are to hold up the plants as they go... It is all fitted together and can slid right up to the table, covering 3 sides, as 1 side of the table is always close enough to a wall for support. The unit stands by itself with 2 different heighs of rails 1 is about 12" the other about 36" above the top of the tub, thus giving support. Forget strings or tying the plants up, let them lean on the PVC. I will get a pic up soon.

looks pretty sweet

Right now im doin a scrog and it working great. It looks like ill get 16 oz off 4 plants. 2 plants per tub is perfect. I think doin flood and drain could be better then dwc because its easyier to control and clean.
