4inch PVC Aero/NFT 4x5 SCROG (1200Watts)

Hello everyone,

This is my first grow journal here at ICmag. I'm keeping a journal on another site and I'm too lazy so I'm just copying and pasting it from that site. That's why all of my pics say property of another site.

Actually you all are going to get to watch me embark on my first attempt at Hydro. I've been growing in soil for some time and have decided to build my own system.

With a lot of help from a friend on another site, I've put together a 9 site Aero system that may interest some of you. I cannot take credit for this concept. I simply modeled my design after my friends. He's the Genius. I'm simply a Copycat.

I'm going to take you through the construction of the unit itself, then show how I've placed it in my growspace. I'll also show how I configured things and talk about how and why I did them. On Monday I'll be loading it with 9 clones from a (Nirvana)Snow White Mother ...and away we go. I'll be placing a 4x5 net over them in order to get max yield. I'm hoping for 30 ounces dried.

Ok so let's talk about the unit itself:

I wanted a Hydro unit. I wanted at least 8 sites. I didnt want to have to mess with soil or hauling Distilled Water anymore...it was too much work. So I decided to spend some money and do it right.

The design is fairly simple; Three seperate 4' sections of 4inch PVC each with 3 sites. These pipes are spaced 1 foot apart so that gives all 9 sites an even 1 foot in every direction to fill out if I'd ever choose to grow without the SCROG net. There is a 3/4" slope from the 2x frame which holds the ends of the pipes so that the water will automatically drain back into the 45 gallon res. The entire unit measures roughly 42"wide x 55" long.

4in_setup_007.jpg


This shows the spray pump which is a 633 eco. I simply built the 1/2" PVC arms and fitted it down to accept 1/4" vinyl hoses. You'll also notice the drain in the bottom of the Res. Remember when I said I didnt want to have to carry distilled water anymore? I meant it. This res has a dedicated drain line(garden hose) and a pump which pumps it through the wall and into a bathtub for quick, easy, drainage.

4in_setup_003.jpg


drain_pump2.jpg


pump_hose.jpg


Here you can see the basic setup of the pump and site hoses. I went to Wal Mart and got the little tees in the section where the Aquarium supplies are. They'll fit 1/4" Vinyl hose.

4in_setup_008.jpg


The Vinyl 1/4" hose carries the water to the sites and then hits the sprayers which are positioned within 1/2" of the plant site.

* NOTE * I bought a 633 thinking that it would be more than enough to spray water 2 inches with basically 0 head and was surprised to find that it didnt even come close. I had originally drilled the hose holes 2 1/2 inches to each side of the 2 inch pots. I had to reposition them to within 1/2 inch of the pots. Now the stream reaches the pots just fine. The rubber grommet is a 6mm grommet. The hole was drilled with a 7/16" bit and the grommet makes a nice snug fit. The sprayer is a 333* head. The Red or Green 360* sprayers work too. These are 2 inch pots with 2 inch Neoprene holders. We go from clone to Harvest in this system. No BS hassle.

4in_setup_013.jpg


potneoprene.jpg



I put a Bulkhead fitting on the bottom of the tub and threaded a 1/2" watter hose valve up into it. When it's time to flush my res I simply open the valve and turn on my drain pump (350gph) and it drains out the bottom. I siliconed it and used teflon tape and it doesnt leak a drop. Notice that the res sits on a heavy duty stand. I had to leave room for plumbing underneath and this also allows us to place a catch tray of some sort just incase it decides to leak. It's better to be cautious. Don't skimp on plumbing.

4in_setup_004.jpg


Speaking of don't skimp...... Give your plants good water. Invest in a Reverse Osmosis system. 132.00 on Ebay all day long. City tap water is garbage. PPM of mine ran 300 with PH of 7.8 .... yuck. After installing my RO unit my water is 0 PPM.

4in_setup_014.jpg



However, oxygen uptake for roots is best from 65 to 69* so we have to keep our res cool to avoid Algae/disease. That's where my 1/10 HP chiller comes in. This will keep my res at 65*, 24 hours a day. It's pricey at (355.00) but it's the best insurance against disease.

chiller.jpg


Here's my RO unti installed. I'm no plumber. Trust me, if I can do it, ANYONE can.

ro_waterset.jpg


Now the RO unit feeds this 30 gallon Rubbermaid RO res which then feeds my Nute res through the wall via a 1/4" vinyl hose.

ro_res.jpg


Notice that the drain hose(garden hose) comes back through the wall just under where the res feed goes through. My flower room is obv right on the other side of the wall.

rores_line.jpg


pump_hose.jpg


Here's a shot of the res with the top on. Notice the lines coming through the wall. The black 1/2" Vinyl hose is the in and out to the Chiller.

hoses_res.jpg


So here's a look at the spray pump after all the vinyl hoses have been hooked up. See those brass tees? You need them to build this system and they're 46.00 for 10...lol anyway, you can see the water draining back into the res as the sprayers are on in this picture. Notice the float valve in the rear....that's what feeds the nute res and keeps it from overflowing.

waterfall_res.jpg


Here's a look at the Chiller pump. Mine is a Danner 500gph mag drive pump. It'll keep your res circulating at a cool 65*. It sits right beside my res.

chiller_pump.jpg


The spray jets in action. I simply attached them using zip ties. The white Duct tape covers the old holes.

spray_pipe.jpg


Now, here's the system as she sits. The flower room is 7x7. There are (2) 600 watt HPS units hanging overhead.

No dirt, no carrying water, no hassle. The beauty of this unit is that I can place the cuttings right into the 2" neoprene pots and start spraying them with 200 PPM water and in a few days they will root and away we go. I go from clone to harvest in this. There's no need for a veg room, only a place to keep a mother which I keep right in the bathtub where my res drains.....

systemfinal_017.jpg


mother13.jpg


I keep the mother under (4) 26 watt CFLS. I'll cut 9 clones and go. Right now she will only yield 5 or 6 good clones. I need to wait 3 or 4 days and then I'll be ready.

Anyway.... here's how I set up my flower space:

Empty room with a 5000 BTU window AC.

emptyroom.jpg


The res stand with hole cut to accomodate the drain.

The unit with the 4 inch holes cut into the front. That damn 4 inch hole saw blade was 30 bucks! lol

frontres.jpg


Rather than tape Mylar directly to the wall I built a 1 1/2 inch PVC frame and draped Mylar over it to provide some reflection for the 600's.

Here's what I'll be feeding the ladies. Also, you've got to invest in some good meters to keep track of your nute res.

I've always wondered what it'd be like to lose all that dirt.

Good Luck

Nice, clean and well thought out! Props! I love NFT!!!
I'm in my second week of bloom and the growth rates and overall health is great.
I'll be watching for sure! Thank you for posting it up!
Oh yeah, how long do you plan on vegging the 9 For a scrog? I have vegged a sog grow in an aerofloii and had stalks break through the netcup, and started cutting into the stalks! I only vegged like 3 weeks to pull as many cuts off the sucker branches and give my bubba a few more tops.. Big mistake! I ended up cuttiin 2' off the ends and doubled up on the holes. My 120 turned to 80 sites and I flipped at 8"... OH MY GOD!!! Under a 1000w HPS in a tube air cooled I got my pound and some change.. Start to finish in 70 days from when I took cuts.. I rotozipped 4" sqares from the circles and just filled it with 4x4x3 cubes and pulled the laser line out and replaced it with 2 1/4" dripline per tube. Added a nft-1 timer (1 min on, 4 off, and that system is now at a friends house w a single 600 in a PL with a rail, and he's using floranova and getting 1+, and he don't know shit about growing! He just pours 8ml per gallon and tops off with RO 1x weekly and drains n refills. He has no meter, no ph reference and he's growing top quality medicine and plenty of it!
You look like your going to be very successful with this setup and you made it so easy to do all the gruntwork. Sorry for rambling but AU has it right w NFT. I warn you about sprayers... Their a liability with any system, and they play with PH a bit so watch out! That's why I went full NFT. Not much to clog on ya. Let her rip Mon!

Oh yeah I had that same gold tote w wheels from walmart, and when I filled it 2" from the top, I had suddenly realized that solution was leakin from upstairs, into my office/studio and ruined a midi controller, and my sub. It leaked right at the 90 around the wheel. I've used many totes, barrels, trashcans and that rubbermaid wheeled tote was the first to leak from too much water in it. I saw heavy duty 50 gallon black storage containers that were really tough and cheap ($30) I'd hate to hear you lose a crop over thin ass plastic. Just some food for thought.

Thanks for the kind words. I'll leave 10 inches or so between the pvc and the scrog net. I'm guessing I'm in for 6 or 8 weeks of veg (just a guess since this is my first Hydro grow).

I read your journal. Very nice.

The Gold tote is a Rubbermaid Roughneck. It's been fine so far but thanks for the heads up.

FYI.... I'm spraying them with RO water, PPM = 200, PH = 5.8, Temp = 74*

Once they root I'll switch the spray pump to 10 minutes on and 30 off, raise the PPM to 400, Ph at 5.6, Temp at 66*.

I'll veg them at 600 PPM max with AN sensigrow.

love the detail of the set up!! lots of work but it will be well worth it im sure.

Today is the first res change. I've been spraying the clones with 200PPM of sensi grow A set at 5.8ph and my chiller is set to 74*. This is the 6th day of spraying them with a cycle of 20 minutes on and 1 minute off. The clones are barely starting to root which is nice to see. I'm anxious to see what happens in the next 7 days.

That is a sweet setup that you have there. Also, the way that you explained it was pretty easy to follow. If it's not too much off a PITA, can you make a parts list for this(I read it carefully, but I know that when I go to put one together it would take about 20 trips to the hardware for this part and that part). This should be a sticky either way though(who do you talk to about that kind of thing?)

Plain water works! But Phosporous will blast roots in that machine, I luv that you can use that system from start to finish. The only thing I would suggest is you build another system just like it and run 1 600 per system!

Today the roots are clearly starting to show. I shifted the water temp from 74* down to 66* but the PPM stays at 200 until they get good and rooted. PH = 5.9

Timer still set on 20 on and 1 off until all show roots 1 to 2 inches, then I'll switch to 10 on and 30 off.

My city water is 250 PPM and 7.8 PH. I needed better water. Can you elaborate on your Phosphorous comment?
