Hydroponics How To: Build a Deep Water Culture Hydroponics System

[Gamer7143]

damn when you were drilling the holes through the stirafoam i got chill through my body cause cause of the noise...hahaha

[mrswizzful]

why does it need to float .. wouldent it be much easyer to use a lid? strange .. guess you like boats?

[oimmuk]

Just tried to go to Sure to Grow website from the link and got a message of a possible malwear issue so thanks I will watch what it says but I am not going to buy from there.

[SureToGrowers]

@oimmuk Thanks for letting us know. Try Hydro Media Ulimited to purchase STG, best prices we have seen.

is hydroponic food safe to eat if flushed

[YouTubzie]

If using an RO do you have to worry about BPA's?

Never did get an answer...oh well...it happens!

"... concerns.

Best of luck with your grow.

Well there you guys go, good luck everyone.

[Duckyistrippin]

@Untsaiyi these guys are largely full of themselves. but to answer your question quality air pumps are generally rated in LPM{minute}. the depth of your system will vary how much air you need. Get a big ass pump and LOTS of air stones. more surface area the better. you want bubbles everywhere! get an alita or hiblow air pump and you will be good to go. get the alita silicone diffuser tubing, weight it and cover the entire bottom of your system with a coil of this tubing. you are now golden :)

[Untsaiyi]

@Duckyistrippin Thanks mate, I'll definitely look into that!

[Untsaiyi]

"... the store you are buying the pump from. Pumps also come with different ratings. The point we are making is using air will be very helpful to your grow and plants.

Our videos are designed to help and educate growers and point them in the right direction whne thinking of building or buying a hydro system. We are not consultants and are a little uncomfortable answering questions that can have variables that we are unaware of that can have unintented impact. Hope you understand our..."

[Untsaiyi]

I got an response in PM and thought I'd share it with everyone. This looks like the best we'll get from them:

"Re: Question Regarding A Video You Uploaded

Thank you for the question. We have addressed air pump questions in the past and are not trying to duck the questions that keep coming regarding pumps. Because pumps can be used for hydro different system applications, in different sized systems and unique applications, our standard answer is to discuss your application and system with... "

[Untsaiyi]

I have a question about air pumps. You say 28 liters air per gallon water is optimal, but I'm a little confused...

Say I have a 950GPH air pump... that's roughly 251 liters per hour. So do I divide that 251 by 28 to see how many gallons it can support? I.E. ~9 gallons? Or am I doing it wrong?

I suppose I'm mostly confused because pumps are rated by the hour... and I don't know if I need 28 liters air per gallon every second, every minute, every hour, or... what? Thanks.

[espencerrrr]

@Untsaiyi

I have the same question as this guy

[jbat3535]

@Untsaiyi its assumed per hour, since that is the standardized unit

[stopbiatch]

seriously believe your friend with the forehead is a bit retarded

[eyewannagofast]

i'm building a larger scale of this setup, one question i'm using a 4x8 tray that the plants will sit it,, if I don't want to use the sure to grow cube or the floating foam,. my thought is 3 gallon smart pots sitting in hydrocoil red rocks. would I still need air stones under the rocks? wats your thoughts about that design?

[bmcbride1982]

you can just put the holes in the yellow lid...and not need a water pump at all just air stones and a perculatin tube that uses another ai tube to push the water up...and throw a fogger in there:)

[myReddog13]

I think you need to check in to the plastic that you are using it might not be the right type.

[xavi6612]

Me as well i would like to know about the 28L of aire / gal of water.

How often you need to do that, is it per min, per hour ?

Thanks

[1982FMJ]

stainless steel chambers are quite good. they keep the water cooler as metal is colder.

[lookoutbitch]

if im growing indoors whats a good way to control water tamp???

[dannygeale]

Hi Sure To grow i jus want to start by saying thanks for the DWC Idea i made a 30 site bubbler cloner and it works well But

im having trubble keeping the Ph stable im using a ph down product but the Ph keep raising

i normally ph the water to 5.5 a few hours it can raise to About 8.0 what could be causing the ph Swings ? if i can get the ph sorted this cloner is the best thanks

[eyewannagofast]

@dannygeale Only idea I have for ya bro is use Reverse Osmosis Water,, if your not already,, if ur using tap water could be that you have hard water in ur area, hope that helps, Grow Green!!

[mangoodvid]

i dont understand... do the roots just grow in the water, or do u put a medium submerged in the water for the roots to grow in.

[NaturalMystic072010]

Great video how to however it is stated that you need 28 liters of air per gallon of water in the the grow table. Question, pumps are rated at liters per minute so do you mean 28 liters of air per gallon of water in the grow table per minute? If otherwise please let us know?

[rcacad]

@NaturalMystic072010 did they ever respond to your question of 28L per Gal either being LPM or LPH? Im making a 10gal 11 plant box and im in disbelief at the need to bubble 576lmp in that. Who would ever buy that many air pumps for a single box? I found 100lpm pumps that weigh 11lbs and cost 119$ but 6 of them? Thats nonsence and im waiting for clarification.

What about all the people who use 8gal, - 18 gal with nothing but a 40lpm pump and grow bushes and bushes? i dont know

[NaturalMystic072010]

@rcacad I haven't seen anything yet!

[montaramike]

Bubbling air into water does not add oxygen into the water. Water is already fully saturated with gases. The bubbling of water circulates the water and breaks the surface tension which allows the exchange of gases.

[RMRio]

what a shiny forehead... lol

[underdog559]

@RMRio thats funny, cause right when the notice it...i told myself "i bet someone comment about it"...and right when i scroll down...there it was...hahahaha

[GTILOUD]

freudian slip @ 8:25 haha "large pot grower"

[HatchetDesTroyer510]

got a ? on a 23w lumacoil low heat output 1600 lumens are these bulbs good for starting or later on or at all

[cmr5828]

"Mmhm. Okay" "Okay" "Okay!" "Okay" "Mhhm. Okay"

[trojanshawaii]

can u make a video of results?

[twinturbo160]

Also if I get a RO system does that mean I dont need to worry about the PH?

[SureToGrowers]

@twinturbo160 No you will still have to PH your solution, however starting with RO water will allow you to dose your nutrients right off of the back of the bottle with little to no issues with PPM's

[rcacad]

@SureToGrowers So your telling me that a 10gal setup needs 567 Liters of air bubbling? Thats 37.8L x 15( min. multiple amount you suggest )? Thats 6 100lpm 119$ pumps for one box? WTF are you saying?

Tell me this is a mis-understanding and when u say "Liters" per Gal, its Liters per Hour and not Lp min.

I can live with a LPH amount of air but practically speaking that requirment of LPM for a 10gal setup is almost impossible.

Ive seen many awsome grows with one 40lpm pump, whats up?

help!

[SuperGaryOak]

Energy inefficient*.

[redicculus]

DWC is probably the cheapest to put together, but the most prone to pH and nutrient swings.

Another great video, guys.

[TheTorah]

nice video guys. very informative. thanks again

[monteros]

Thanks guys. Keep em coming!

[drkirchner]

Great video! One question though, How would you determine how much water would you need?

[chocoff]
