Hey all, Great info on this forum and some amazing grows!

I have a question about a PPM meter.

Currently and on my last grow I had some problems with yellowing leaves, Im assuming its either nute burn, cal mag def problems.

I am looking to get a PPM meter and dont know which route to go.

Any suggestions on which work the best for the money? I cant spend too much I just bought a 600W Galaxy.

Any great sites or ebay that have the model I should get? Any links would be more then appreciated!

PS- If you have a chance please look at my thread in plant problems I have pics and everything I cannot figure out what is going on.

(I did a PH test lastnight (6.0-6.5) and today the first test showed 4.0 or lower. Then I stirred the water up and it was 6.0 +- a few points?) Its a wicking system with airstones. The res is very small and needs to be topped off every 2 days or so.

You can find the TDS3 on the 'bay for under $20 shipped. Work fine. Have bought them for gifts they're so cheap.

get ur hands on a blue lab stick/truchion its water proof and pre-set for u .

its not that cheap like £65/$110 man but itll last for years man

the hanna primo is 20 bucks and works great,theres also oakton. ,blue lab industries,milwaukee,hm digital. lots of companies all in all they do the same thing.if u do go with the hanna primo remeber its not water proof.

Are there any good ones in the 30-80$ range? Whats the benefit of waterproof?

Any links would be great.

wellthe bennefits of being water proof are,well the fact that its water proof sooner or later your going to drop your pen into the bucket that your mixing your nutes into,trust me it will happen.i dont think i have met a person yet that has not done it.umm hm digital has 2 hand held pens that are water proof the TDS-3 and the comm-100 i have never used either of these.i use the cheap hanna 20 doller primo and it works fine. look around the net.your not really saposed to put links to other companies and what not.remeber when u do get a tester to get a couple of small packages of calibration solution.

Sunleaves makes a great TDS meter that is like $35. I've had mine for two years and it has yet to fail me. I would say the only downside is that its hard to calibrate right on 1000 PPM, so its usually off by like 20 which is pretty trivial. Also I am not sure if its waterproof, I've never dropped mine into the water.

If I were to grow cannabis, I would only do so to supply myself and my close friends. Doing this would take myself and my friends out of harms way by knowing the source of our cannabis, as well as take hundreds of thousands of dollars off the black market annually. It would also lower the demand of black market cannabis, and would ultimately help keep cannabis out of the hands of minors.

What do you guys tink about the wizzard constant meter? Its only a couple bucks more then the blue lab.

just go with the blue lab man they are really worth there money!

I use the sunleaves one and its great, decent price and u can pick up the 1000ppm solution to calibrate it when ever u want.

I bought that one tonight!

I bought Fish emulsion and Bot Sweet and The flowering fert with high phos, cal, mag.

I added a good amount of fish emulsion and the PPM is at 1200 now, previously it was only at 600.

1200 ppm, how old are your plants from seed or cutting?

One is roughly 4 weeks into flower
The other 2 weeks into flower

2 clones
both at a month i would guess.

Why? Please give me the proper advice.
I just added some voodoo juice tonight.

a ppm meter is useless unless u know what you're looking for. seedling's 50-150 unrooted clones 100-350 small plants 400-800 large plants 900-1800 ppm.your ppm are fine for your older plants. but do not use the same rez water for your other plants.

Thanks for the info brother,

I will post which nutes im using this week and what suppliments I have as well and hopefully we can cook up a good nute meal.
