Deep Water Culture Growing Q & A

Re: Stealth Hydroponics Deep Water Culture Growing Q & A

question!

I've been following the Deep Water Culture walk through that Roseman has so graciously been providing us (great read so far btw). A couple times its mentioned to "take out" the water pump at some point. Is the tube feeding only for the veg stage? I thought it was in for the whole grow, but apparently I missed something in my studies.

I haven't started yet. Still patiently getting my ducks in a row. :nomo:

Thanks for the info. I appreciate it.

Thanks again, they all don't ship outside the USA or Canada. I'm thinking that i might have to make 1. What is the best flow rate to go for. I could adjust each 1 with 1 of those valves, put it into a jug & time how long to get a liter, then match them all. What do you think is the idea rate for say a minutes flow?

Again your help is appreciated.

2 gph or just a slight trickle.

The submersive pump and feeder tubes are the key to the very rapid growth, but it is just not that needed or helpful, after the first 3 or 4 weeks. After 3 weeks, the roots are in the deep water and can drink and eat all they want.
And after 3 or 4 weeks, the roots will be growing into the pump and tubes and choking it up and leaving dead debris in the pump that will mess with your pH.

Deep Water Culture Tutorial, SH Kit & DIY

Preface, This is NOT a Grow-Journal. It is a step by step HOW - TO, or a TUTORIAL. I hope to share a very detailed tutorial here, with many pics, on growing a pound of dried, closely manicured indica buds in a closet. I will use a store bought hydroponic KIT and also use a DIY 5 gallon bucket...

There is an Hyper Link Index on page 17 and 18.
 
Re: Stealth Hydroponics Deep Water Culture Growing Q & A

Good Read Roseman. I plan on using the SH Deep Water Culture kit with CFL's. (BTW-looks like their prices have come down since last time I logged on) If I put it in an enclosed space, what is a good method to create air exchange in that enclosed space? For example if I build a "Stealthly" cabinet 2' x 3' x 6'. Also at what rate of exchange should the air be and how do I calculate that?

Howdy there. I am taking the plunge into Deep Water Culture and starting my first hydro grow. I hope you can follow my journal Roseman and provide much needed/appreciated feedback/support.

In an enclosed space, you must have a FAN and VENT, pushing air out and another one pulling the air in.

I don't have any info or experience on enclsoed spaces. I'll invite a few of the Deep Water Culture to come answer you.

Hey Green007, good thinking there going with the cfl's in a small space, they'll be a lot easier to keep cool than an HID would.

As to the actual quantity of air you'd need for air change is accomplished pretty easily. I just did a small grow closet myself, 28" x 42" x 60", my intention was to just use it for vegging, well now I'm using it for flowering too. But I put 8- 55w cfl's in there for the vegging, with it closed up tight I was running close to 100 deg. I installed a small bathroom exhaust fan that moved 50 cfm of air, and drilled 6- 1" holes to let air in. That has solved the heat problem, my closet stays close to 80 deg max when the light is on.

So, 50 cfm in a closet that is approx. 41 cf. This means that I'm giving my plants a complete air change in less than a minute, I have no figures on it, but I'm guessing this would be more than adequate.

A couple of problems though, that damn fan is noisy! Look into computer fans, they run much more quiet, and the price isn't too bad, about $21. Just be sure you get one that uses ac power. Most are powered dc, same as a computer, but you don't want to mess with that. The best is to get a dc fan that has a converter built in, they are the most quiet.

Hope this gets you going. I'll check out your grow journal.

Join the Club! Join the Deep Water Culture

We Grow Hydro in all of it's forms and specialize in Deep Water Culture and DWC (deep water culture). We firmly believe in paying it forward for help received and we get our kicks from helping people that used to be just like us - new growers with a willingness to read, learn, and understand to produce the medicine we need/want. We learned from those before us and continue to do so with the shared knowledge that a group of growers with a single mission can provide.

Our goals are many but I will state a few here:

The help all growers, with special emphasis on the new hydro grower, achieve a good crop the first time they are ready to try.

To teach with patience and respect as a means of helping the new grower become comfortable to ask us any question on growing and for the helper to learn as much as they teach.

To become ambassadors for the legalization of the wonderful medicine we grow whenever and wherever that will lead.

To support each other in our hard times and celebrate to good times with equal passion.

After we complete a successful grow with the help of the Deep Water Culture, we pleadge to stay around to help others as we have been helped and thereby spread the knowledge and continue the peaceful cycle of payback/payforward.

And to understand that some of the people we meet here are in true need of these meds and have good days and bad days just like in the real world.

Peace and fun are what we seek!


How can you join our band of growers?

The old ph rollercoster make sure that your res temps are between 65-70*
what kinda of water are you using are you in veg or bloom are the tubes still in and the pump there are many factors to consider and there is always
correct Ph Ammonia tabs to stablize your ph found in wallmart in the fish

Get you a bottle of liquid ph down,(i buy em by the gallons) Give em 1 -2 ml of down at time.Stir and mix real good,wait a couple hours and check again.Repeat accordingly.
 
Re: Stealth Hydroponics Deep Water Culture Growing Q & A

thanks for the advice olias and purpdaddy i think i've sussed it it's the ph down i'm useing instead of getting the normal ph down from the hydro shop i went with the alternative nitric acid which gives your plants extra nitrogen and it doesn't cause nute lock out i used on my last grow (in pots) so i assumed it'll ok for the bubbles. so it looks like i'm going to have to ride the ph coaster till i can get to the hydro store this weekend :thankyou: both for replying RoorRip peace
 
Re: Stealth Hydroponics Deep Water Culture Growing Q & A
