How important is the Bubble in Bubbleponics?

Hey guys, How important is the amount of bubble in a DWC setup? I always thought the point of the bubbles was to splash onto the cup/roots (like an aeroponics system) for nutrition but now I'm hearing that the point of the bubbling is to provide oxygen to the roots (standing water has no movement and thus very little O2).

Is there a direct correlation between the amount of bubbling and plant health (e.g. few bubbles = poor performance; many bubbles = high performance)?

I have a 10 gallon tub (smallest one I could find at Wal-Mart) and I bought 2 6inch bubble wands (air-stones were sold out, of course). Can 2 6 inch bubble wands generate enough bubbles for a 10 gallon res? I certainly don't want to cement these wands into the tub if not.

ye man always think off it this way= THE MORE BUBBLES THE QUIKER THE GROWTH!!
i would defo use an air stone if u can get hold of one if not get a couple of those wands in each bucket
hope this helps
good luck n post sum pics..

More is better, but you can get good results with a small pump if you keep the diffuser directly under the roots.

Bottom line; can 2 6 inch bubble wands generate enough bubbles for a 10g tub? I''m using the Walmart pump with 2 connections (the $10 one). If not, I can try to find a smaller tub, I just don't want to cement this stuff into the tub and then learn later on that I'm not getting enough bubbles to be effective.

how many plants u got in each tub?
2 in each tub will b ok if there aint loads of plants in there get me?

What's the g.p.h. of the pump?

Bubble wands are nice, but you don't need to be cementing anything. If you have 2 of them, then they'd be good for 2 plants in a tote. Now the size of the plant you can grow is directly related to the output of the pump. When I have a go in 5 gallon buckets, the smallest pump I use is a 28 g.p.h. and it's good for a big plant..... bigger than any 2 you could grow in a 10 gallon tote without them battling each other for space, dig?

The pump is rated @ 2800cc and I now understand that I need 500cc per gallon minimum so this means that my pump cannot handle a 10 gallon tote. I'm going to go buy a 5g tub.

How large should my bucket/container be?

You have several options here.

First,are you going to be using a bucket?
A rubbermaid container?
Or something else?

The easiest size bucket to maintain would be a five gallon bucket. These are the common size used by most people who decide to grow using the DWC method.The smallest size I would recommend is the 3.5 gallon buckets if this is your first time growing in a bubbler. If you have already had some experience with this method,you could try using the 2 gallon size buckets. Just remember that the smaller the bucket, the more maintenance will be reqiuired.

A 2 gallon bucket will require daily maintenance to top up the reservoir as the nutrient solution evaporates and transpires. The pH and TDS of the nutrients will also require daily maintenance. The 5 gallon buckets are more stable for the simple reason that there is more volume there. So just keep that in mind when choosing a bucket size...the larger the bucket, the more pH and TDS are stabilized and less topping up. Smaller sizes are less pH and TDS stable and require frequent topping up. One final note is on bucket color. The darker the bucket, the better. Black buckets are perfect for DWC as they dont let any light into the container which can lead to algae growth. If you cannot find black,use the darkest color you can find. If you choose the white buckets, wrap the buckets and lids with several layers of duct tape or anti-corrosion pipe tape.
