shallow tubs

xxxxxim looking to start a grow so my old lady will stop wasting money im gonna build something like the bubbleponics thing but im thinking of using a wide tub but a little bit shallow so that th plants can get more space.

any concerns i should be having?
the pic is an example only ill probaly be looking for something a little bigger i just dont want to waste nuets using too much water. i could use a 35 gallon sterolite tub 27x17x17 but thats alot of water





altho now that i think about my big tub could be perfect. fill up the tub 1/4 of the way so the roots can dangle. maybe preventing root rot. and if somin dies easier to remove. maybe the roots dont get tangled. but im no way a grower yet. so i dont know how my hypnosis is true or not.

no one has any input?

Im currently using a shallow tub setup, but its my first operation. I've been around growing but I can't call myself a grower either (yet!) I'm doing 10 plants in about 5 gallons of water, and they drink it fast. I'm about 3 weeks into it right now, starting to flower in the next few days. I feel like I'm saving a ton of nutes compared to what i've seen done in deeper tubs so i agree with that hypothesis but I think I'm going to be adding A LOT of water OFTEN. In about a day they can drain a few gallons already - I have 4 100% sativas and 6 mostly indicas. The tub is just a rubbermaid or whatever from walmart. My roots are getting mixed up pretty quickly but if i needed to it looks like i could seperate them pretty easily. I think the biggest challenge will be keeping the water at a level deep enough so the roots can drink up but still have enough air so they dont rot.

Heres my thread on my grow check it out I add pictures with progress let me know what youre up to!
