new idea just thought of this does anyone think it could work?

[svchop889]

basically its a net pot on a pivot resting in a resivoir containing an airstone. the net pot will have an ''flag'' or way to catch air from a circulatory fan until the plant is big enough to catch air on its own that way a current is not needed

bump bump anyone?

I don't get it.

What are you trying to achieve?

 

[svchop889]

um cheap hydro

 

[svchop889]

i dont have money for water pumps so instead of moving the water i tought why not move the plant instead and oxygenate the water with an airstone

I think your plant will be spinning and get dizy.

 

[tnrtinr]

There were guys talking in another thread that said as long as you submerge the bottom of the pot in the water with the airstone running you will be fine.

I have never grown DWC but I think the pump is redundant. The roots are submurged in oxygenated nutrient solution, I don't get why they need a pump running water over a few inches of root.

it wont spin smart ass lol it will rock back and forth thats it

so this set up will work then in theory? i just like to think outside the box and do things different

I think it will work just as well as not having it.

You can get a pump for 12 bucks at petsmart if you are concerned.

I am going to try DWC soon without the water pump, just the airstone.

 

[svchop889]

what if there was no airstone in the res and it only rocked? would that still work? theres sorta a current at least there is some movement

There are plenty of hydro systems that don't have water pumps.

i.e. Lettuce Rafts.

would it even be considered dwc at that point if ther is no current? im assuming dwc is an acronym for direct water current

I don't think so.

The airstone is to oxygenate the water. A rocking plant or a fan is not going to get the oxygen saturation high enough.

Air pumps / air stones are cheap. You can get both for less than $20 at wally world. It is the most important component of the DWC system.

Deep water culture.

For either this or the lettuce rafts you need:

1 Bucket
1 air pump
1 air hose
1 air stone
1 net pot
grow medium
nutrients

Styrofoam if you are making a lettuce raft or a bucket lid if you are not.

I have not grown using DWC - but I can assure you that everything you need to know can be found in this section or a few keystrokes of google.

I run deep water with just an airstone and I have no problems at all. I have only been growing for a little while but my set up is this. I use 20 gallon rubber maids with 3 plants offset, up to today each tote was lit with 150 hps over each tote. all I use is a 6 inch airstone on a tetra3 airpump. I have been able to yeild about 7 ozs off of each plant. today I added 400 more watts to the room. I fill the tote full with cutting edge nutes and I leave it alone untill its half empty. then I top off for one week then I drain out completely and refill with cutting edge again. and when it is 3/4 empty I top off with just water for a week to two flush. I cam post some pictures of it will help but it is so simple and hasn't let me down

I wanted to add my total cost is 3.50 for the tote
5 bucks airpump

2 bucks airstone
89 150hps

what if instead of a that flag thing i made a straw that caught air instead and blew bubbles into the water?
