EC is actually ms/cm (microseimens per cm).
And your pen measures in us/cm (milliseimens per cm).

So if you pen says 200 us/cm then that is 0.2EC.
If the pen says 1000 us/cm then that is 1.0EC.


You can use this convertor so you don't have to fuck about........

Change the input value box at the top to microS/cm and when you put the number that your pen reads in the space next to it and click the calculate tab at the bottom you'll get the corresponding readings in all the boxes.

The EC will be in the EC box.

Most of those pens are only calibrated to 0.5EC though which is pretty much useless for ganja.


You're best off getting a proper EC pen, they usually go up to 10EC which is way higher than anything would ever need.
I rarely go above 1EC.

I have an Essentials EC pen that cost me about £40, which is cheap for a half decent pen.
Ebay says £36.85 for the cheapest one I can see at the moment......

You can get away with a cheap £5 PH pen but not an EC pen unfortunately.
An EC pen is an investment.

After having a quick play on there it looks like i just divide the us reading on the meter by 10 to get the EC, cheers for that mate

 

[R1b3n4]

So then tap water here is roughly 0.7EC, whats max Ec level i wanna go to at various stages etc? anyone got a handy picture/graph etc

 

[R1b3n4]

0.7 down here lol

Knowing that from understanding nutrition ratios and reading your plants at each stage is what makes a real grower and sorts the men from the boys.

It's not a black and white answer.

Ratios are more important than overall EC, but you can't do ratios with 2 part commercial feeds.
With 2 part or all in one feeds you get what you're given and just have to work with it.

Assuming the PH is right mind you, if PH isn't right EC doesn't mean shit cos the nutes won't uptake properly.


I rarely go above 1.0EC, 1.2/1.3 is the high end intermittently and 1.5 depending on ratio for defs.
Even then I don't feed with every watering.

That's pretty good.

It's not what I was thinking of.

 

[The Yorkshireman]

That's hard as fuck to be 0.7EC.

Mine's 0.2EC.

I feed plants up to mid flower at 0.7EC most of the time.

 

[oscaroscar]

Yeah they have sent me different to what I've ordered a couple of times but they were always around the 180 mark in my guesstimation. I usually get a couple of the new press testers in the mix too. last ones were black dominoes the same size as the original silver bars. I've never had a prob with any of their beans but I get you wanting what you paid for not what they've got at the time.

It is unusual for them to have not been online in 4 days tho yer reet. You not rather get a bag full of grit and some gel caps and do it proper?

Like I said. They ain't for me.
I've ordered elsewhere for about the same price. It's been accepted but not shipped yet.

 

[Lemon king]

Nobody in this thread buys shitty product.

Lemon is the exception, he doesn't know what quality is and punts shitty product as top shelf.

Im sure i can get some shitty product your way yorky if you fancy it yorky ...

Always happy to let the buds do the talking......

I've had a bulk request so I'll be looking into a new vendor if partyflock look like they're going dodgy.

You order domestic or Europe?

NL. I can't remember the vendors name just now though. They had decent numbers and feedback. I'll look in a bit. I can't do it from my blower. I've got a stupid iPhone.
I'm still pissed off I got stung by that CQDX cunt though. It's only £25. I've messaged him but he's not been online for four days. It's been nine days for a domestic delivery so I reckon he's stitched me up the cunt.

 

[Don Gin and Ton]

I never managed to figure it out on my bugle. Christ, I don't need to make it easier to order off the DN. Haha

 

[oscaroscar]

I have to do it when she's out because I'm not allowed to do it on the laptop because I blew the last one up lol

 

[Don Gin and Ton]

lol. i mind on. Though it can't have been the DN that did it. you must have the digital death touch haha

Do me a favour when you get on and check the prices for me. Looks like the price on a hundred red defcons is only about £150 from about 3-4 different NL vendors with escrow. usually a couple to a few hundred sales, which isn't loads but there's one over a thousand I'm looking at just the cheapness makes me think scam.
