I have.

The objective is to get the roots in the air
without them getting too dry.

I have gone 5 hours without any spray.

I am just trying to achieve a balance between
just enough nutes and water,
and too dry.

Fine root hairs do not indicate a healthy plant.

I like the results I am getting with 5 on 30 off.

The strain of plant has a big influence on your end result.

Also the lighting.

Keeping the nute loads low
is the best way to improve the quality of your buds.

Light determines yeild weight, not nutes.

can you tell I'm pretty stoned.....

I get it. Thank you. I've been running 1 on 5 off but I've been thinking about extending the off time. Do you only use a 15 min on time because of the increment on your timer?

Bad ass earl, I'm pulling up a seat to watch and learn :)

Wow. Just finished. You grow some amazing plants in Aero. I tried DWC and realized quick about having to keep the water cool. I want to try full on hydro again when I have the cash to start up right. Till then Im in the hempy buckets. :) Thanks for posting such great info earl.

Howdy again Earl.
1500ppm? Does your meter use NaCL Conversion or the 442 Conversion? If your not sure do you know what the EC was? (arround 2.2 or at or above 3.0 milisiemens?)

I didn't weigh the crop.

I have a milwaukee SM401


The numbers on the meter are from a dutchmaster grow.
I can't run that high with AN nutes.
300-400 is where I grow with AN nutes.

Going by PPM can be misleading though as there are 2 differant conversion factors that some meters use. Any Dutch grower I know uses EC instead of PPM.

The NaCl conversion(0.5) or the 442 conversion(0.7). I do belive that the milwaukee SM401 uses the 0.5 conversion factor. Here is where it gets confusing with PPM, You could plug a meter with the other conversion in with that milwaukie and the milwaukie will read its 1190 and the other would read arround 1428. If we were talking Electrical Conductivity instead then no matter the brand/maker of the meter they will all read the same amount of MiliSiemen.

Here is a good article it.

Thanks earl was just wonderin. I'll not start hydro or aero untill I get me a good meter so I'm all ears on this topic. Thanks for the link I'll be checking it out.

1200ppm that's amazing!

1200 was not that good of an idea
and the plants suffered for it.

You know,
there are so many ways to measure the TDS
and in the end,
tds is just a number.

The key is to use the same meter and the same nutes
and then you will learn the numbers.

I am sticking with AN nutes for a while,
and I plan on keeping the nute load as low as I can.

Didnt you also recently change meters earl? wonder what the old ones conversion factor was.

No.

This is the meter I have been using for tds.

I did switch to PinPoint for my pH meters.

I like this Milwaukee meter,
but if/when it dies,
I want to switch to Pinpoint tds.

My Milwaukee pH meter died twice,
so I'm giving up on them

Like I said before.
TDS meters are just numbers to help you keep from screwing up
and you can tell if the plants are eating,
if the numbers are always moving down.

I like the numbers to move down fast.

This means I have to watch it pretty close.

Be sure and spend the bucks for a good pH meter,
because the pH will be the most important number
and an accurate meter is essential,
along with plenty of calibration fluid,

Plan on calibrating your pH meter
every time the rez temp changes a few degrees.

This could be every few hours
if you don't have a chiller.

That is why I love the chiller,
only 3ºf max variation, 24/7.

DYNAMIC NATURE OF ION UPTAKE

1. Regulation at the uptake step: CaSO4-grown plants

In the 1930' and 40's Hoagland, made use of barley seedlings grown hydroponically for about 1 week in solutions containing only 0.5 mM CaSO4 to measure the uptake of K+, NO3-, and other ions.
At a time when measurements of ion uptake were generally made without the advantage of radiotracers,
it was necessary to optimize uptake or be satisfied with experiments that lasted for days,
and therefore suffered from lack of sensitivity.
Hoagland observed that growing the plants this way
compared to growing them in full nutrient-solution,
considerably increased the rates of absorption of all ions except Ca2+ and SO42-.

Actually, the observation was recorded as early as 1906 by Brezeale,
who demonstrated significant increases of nitrate, phosphate, calcium, and potassium uptake
when these ions were removed from the media for 15 h (table 1).

Thus, it would seem as though the plant adapts to the absence of a particular nutrient
by increasing the capacity to absorb that particular nutrient.
