tubing and fittings

hey guys i was just browsing this site with hydroponics fittings and tubing and trying to get a handle on what i need

i want to do a 12 bucket waterfarm. what size tubing should i get for the water and air lines? any idea how much iwill need?

Why not do a 12 bucket DWC and just get 2 pumps that can handle 12 buckets each put a hose from each pump in each bucket and call it a day... Waterfarm is nice but if your not wanting to invest all your money in a fancy setup I say put the money towards a good light, air exchanger & filters...

1/4" air tubing 100', 24 air stones, (2) 12 outlet pumps, 24 anti-back flow preventers (just protects your pump if you place them on the ground), 12 Team water jugs /cooler or other well insulated container this will help maintain temps. What type of lighting? How are you exchanging the air?

Waterfarm is all 1/2" hosing/fittings. The amount of tubing will depend on how
far you want to space your modules. Air lines are 1/4" standard air lines like
you can find at walmart, again this depends on the distance of your sites vs.
location of your air pump.

I ran the waterfarms and wasn't that impressed with them IMHO. I would recommend
some kind of recirculating DWC as this will make changing/adjusting your nutes
a breeze. If you're not into DIY, something like the CAP Ebb and Grow system could
be a good solution, or if you've got some good lighting could try out an under current

I'm not a huge fan of having to adjust the nutes when the plants are sitting in them as
this makes things quite a pita. If you can find a way to either pump your nutes out or
drain them without having to get down in dirty in the root zone, this will make your
job quite a bit easier. Hence why I would recommend the RDWC.

i am planning on a recircuating system. with a resevoir and float valve or similiar. how far should i space my modules if i use a 4x3' t5 12 bulb for veg? i can only have 12 plants total by law. is it necessary to get a 16 bulb?
