the issue is you used 3/4" pvc, you can pick up a1/2" to 3/4" threaded adapter(same place youll find the hose barbs) and use that.

or i believe ive seen the 1/2" male threaded to 3/4" slip adapters also, cant recall off hand.

your thinking of it as the pump as the female end right..

exactly...

OK, I am ready to move my clones to my veg unit, I used the stink veg dual container system and put the recommend nutes in and my Hanna GroCheck is flashing 2000 PPM (that is it's limit, as it is for my veg, I thought one that went up to 2000 PPM would suffice).

What did I do wrong? I added the exact recommend VEG nutes and then set the pH. The PPM flashed around 1400-2000 for a spell when I first inserted probes but then it just started flashing 2000 PPM (which manual says that it is OVER GroCheck limit).

How do I lower PPM? What if I wanted to higher it, hypothetically, in the future?

THANKS et al!

Dilute your nutes back down to the 1200 range by taking out nutrient solution and replacing it with fresh water. Believe me, 2000+ is way way to high to begin clones at. I know there's this whole thread of Skunk saying he starts at 2000....I call some level of bullshit. I have been using Botanicare for several years now and I never go above 1300 ppms....ever! I start getting nute burn at anything over 1400 ppms. Dilute it down and put your clones in....they should be fine. I personally start my clones in the 500 - 600 range and very gently work the ppms up throughout veg and flower...peaking at 1300.

Here's my current grow with Botanicare (Pro Bloom, Liquid Karma, Cal Mag, Sweet) 1000 Watt RDWC Setup

Stink never said he started anything at 2k ppm. He starts at 1500 when the clones first go into veg and then gradually increases to 2000ppm by the 2nd week in veg. I and countless others have followed stinks nute dosage with exceptional results. The explosive growth with this aeroponic system supports a higher dosage, especially during veg, and the stretch when the plants are growing super fast. The key is to learn the plants intake during flower, it is usually a bit lower, along with possible salt buildup and you must stay on top of it or you could get burned.

no bullshit!

When Stinkbud recommends 2k PPM's, I believe he is referring to using Co2 in conjunction with those high level's. If you don't have Co2 and a sealed room/Air Conditioner, then ur nutrients should prolly be alot lower.

My last grow liked 1500-1800 in veg, and 1500-1800 for the first 4-5 weeks of flower. Seems like after the 5th week, the plant goes through a change and can't handle high nutes anymore. Dropped it down to like 1000-1300 for the last 5-6 weeks.

I'm gonna stick with these numbers with the Kush and gradually increase with the addition of Co2.

Hello again everyone. I tried to type up an apology the other day, for the ranting and raving that I did a little ways back, when I was in severe pain and frustrated, but the damn site logged me off right before I sent it, so here it is, again. Lol. I honestly and sincerely apologise for wasting precious thread space on my personal BS. I'll try and stick to posting about the system, use paragraphs, and use a spell checker from here on out. Lol. Oh yeah, and I was also wanting to thank WhiteDiamond for the Rep on the PVC toxicity question that I answered.

Now since that is out of the way, I have a question. Has any one on here attempted to build a system out of fuel pumps and injectors? I think I am going to try it. It will certainly be easier on the clone and veg units. I have experimented with the pumps and injectors, and as a mechanic, I know they put off a much finer mist, meaning even more aeration. I figure the screen will filter large particles, the 12v pump is submerged and powered by an array of 12v batteries, then the solution is filtered with a large fuel filter(possibly a diesel truck filter), then
hopefully the roots are simply and gently sprayed.

I'll start a thread soon if it sounds interesting to all of you. Right now I just want to see what the best grow thread out there has to say about all of this. I'm just trying to share some technical love. I have fuel pumps, batteries, wire, and I am just a few items short of actually doing this thing!

On to the electrical. I mentioned a 12v system comprising of; multiple large batteries wired parallel(anything 12v), a good battery maintainer, timer( the line voltage timers we already use can be used with this too, just to trigger the 12v side), but I think I will experiment with windshield wiper delay modules and try to extend the on an off time, since they use 12 volts also. Can you guess what this kind of setup also mimics? The cheapest and best damn uninterruptible power supply you could possibly have!!! If the power goes out, the pumps never get interrupted. The only thing that happens, is the maintainer doe not charge the batteries for a while. With enough car batteries wired in parallel(positive to positive, and negative to negative) this should have the capability of running for days, or maybe even weeks, with out a recharge! I need feedback on this one fellows. I want to try and figure out some of the kinks before the build. How about it?
