flood and drain table design?

Flood table made from two 4' W x 6' L x 1/2" thick sheets of wood and 2" x 6" studs. Reservoir sitting on floor with table stacked on top. Overall 13" tall to accommodate low ceiling. Covering both reservoir and table with black PVC pond liner, using a pond pump on a digital timer, flood and drain fittings, rock wool, and clay pellets. All under two 1000 watt HPS and using C02. Would this work good for a SOG? Or just one big harvest at a time? Overall good setup?:joint:

Sounds like a nightmare size to me. If you have room to move around all four sides of the table it might not be too bad. That 13" height will be very hard to achieve. What you would have to do is built a reservoir the same as the flood and drain table so that you can get the necessary amount of water in the remaining 7" of height. And then you will have a problem with the height of the pump. You might be better off to consider aero for the height and even then the 13" will be hard to do. VV:blsmoke:
 
There will be approx 12" of room around table. You think the pump will be taller then 6" ? I was planing on having the res and table the same size. I just want a zero maintenance setup unlike aeroponics!
 
Look dude, I built my own tables, I am not saying you can't build one. one foot of space around the outside of a table that big is not enough. You would be better off, IMO to build (2) smaller tables and have all of the room to work around them be in the center.That would give you two feet of space and the res wouldn't have to be as big. these tables are 32" by 48", so about 1/2 the size you are considering, trust me, you won't want to work around a table 6' by4' unless you have more room.

about the sog, thats really hard seeing as you only have one rez, one way to set up your nutes. also, dont be fooled, aero is not by any means low maintence, no matter what system you are running.
 
I like the idea of two tables. Thanks. How much money I have at the time of build will ultimately determine what my setup will be.
 
I know aero is not low maintenance and that is why I am doing a flood and drain! I will need four separate reservoirs/trays for SOG? I guess I wasn't thinking of the difference in PPM's and flushing, etc. . . . .

Would it be better to just buy an ebb and grow controller and build my own ebb and flow bucket system to accommodate low ceiling?
 
im sorry, i meant hydro. my aero unit is actually easier than my drip. just my case though because of simple design flaws in my drip system.

I had thought about suggesting something like that, the parts are not cheap. I have a link to a company that sells the float system and gives excellent directions for how it works etc. The kits is less than $100, and includes 5 float switches and all of the electric DPDT 12 volt switching and work boxes. The res and the controller unit will take up space thought. I'll post a link here, everytime I try to do it in the same post I have lost the post, gotta love old people. VV:shock:
 
say victor victous i was wonder what kind of plant they were and i heard a gallon for ever foot and you table dont look to deep? ho deep is it and how tall can you plants get,me i got a rubbermaid about from walmart 13inches long and 18 inches deep about 4 gallons 6 plant but i dout there all female how far a part do i need them>

https://www.rollitup.org/do-yourself/22115-diy-flood-drain-table.html Here is the build of those tables. They are all Marijuana plants. The one gallom=n per foot of growth is for soil grows not hydro. With soil grows you add water when the plant is getting dry, with hydro you water a few times every day depending on the medium. Because they are being watered regularly everyday you don't need a gallon of medium for every foot of growth. The rubbermaid container you have is more like 15 gallon than 4 gallons and is used by many folks here for thier Aero set-ups, Filthy Fletch posted a 30 minute aero build thread for those.
Generally with hydro you can have as many as four plants per square foot. I recommend you read AL B Fucts journal, he explains the sog system in detail and he is harvesting about three pounds a month. Uhh... I have a journal as well, VV:blsmoke:
