So by keeping the temp between 62° and 68° I am ok then.
Thanks.

re-constituted would just mean to top off right? Or do you mean a full change.

When your nutes get cold, the chemicals will "drop out",
and the solution must be heated to re-dissolve/reconstitute the chemicals.

I'm not sure of the upper temp limit on stored nutes,
but the problem is letting them get too cold,
below 59º according to DutchMaster.

OK I got it now, we were talking about stored nutes. I thought what you said didn't make sense because you mentioned earlier some guys in Canada growing in 50° temps. That was nutes mixed with water.

My stored nutes temps max/min are about 80/65 so I think I am ok.

Thanks for clarifying that.

I think you could run that air cooled CMH at the closer end of the chart.

Yea, thats what I figured. I got Caligrowers chart too. I started at eight inches but but the plants leaves curled down and I got deep veins on the new growth so I figured that was to soon. I backed it off to 12" and they are doing fine. I will drop to 8" in flower.

Hey bud,

I guess everyone has there own opinion as to whats the best for flowering.
From what I have read there are two red and two blue spectrum's you want to hit.

The easiest way to hit them is to use a bulb that covers all four (CMH is one) or to use two HPS to one MH all the same wattage.

I noticed your stems on the fan leaves look red or pink.
I think this is an indication of the pH being too high.
Be sure your calibration fluid is the same temp as your rez,
when you check your meter.
If you are happy with the calibration,
then you may need to shoot for 5.5 instead of 5.7

Nice catch Earl.

I do calibrate with solution thats stored in a warmer place. I cooled it off. I found my pH was off .04

I understand you like pinpoint constant meters. I have never owned a constant meter, are they easy enough to calibrate? Also can you tell me how long the cord is from the meter to the res?

Thanks man.

So far I like the PinPoint meters.

They are not temperature compensated,
but they work well
if you keep your calibration fluid
the same temp as the nutrient rez.

Using a chiller also keep the rez temp closer to constant
and that contributes to more accurate readings on your meter.

Temps 90 res 64°
Ph 6.3 backed to 5.4
PPMs 340

I turned the thermostat up a bit and kept temps around 90° Today.
Had that mishap with the Ph meter but I got a lot done today on cab 2.

I got another thermostat for it and hooked up the ventilation.
Added the light and timer and finished off the clone chamber. I still need to get another small pump for the res.

Looks like the Hydrofarm air pump I got with the waterfarm will be enough to run a couple bubbler's.
Hell it ran eight water farms. I got a few air stones a couple eight inch sticks and a flat 12" I think.

Heres some pics.










Heres a close shot of the stems.







Im getting the hang of the macro on this.
Its got a super macro too but I havent got that figured out yet.


This is what I was doing most of the day.
Almost done.
Cab 2

You do nice work.

Thanks Earl.

Maybe one day I will have the space you have and can duplicate your space shuttle.
This is all I can do with the space I have.

Buy the way, after making the adjustment on the ph and letting them run for eight hours
I noticed a difference. The grow was only using about 1/2 gallon of water a week. PPMs were
slightly lower but mostly the same.

In the last eight hours the grow used 3/4 of a gallon of water and the ppms went from 340 to 240.
The plants grew an inch I had to raise the light.
If it continues at this rate I will be topping off 5 times and changing the res twice week.
I understand I will need even more in flower.

I did a res change today.

Temps 90 res 66°
PPMs: nutes 390 calmag 120 total 500PPM
Ph 5.7

Ya know, what you could do is just get one more 400w HPS and see if that will get you what you want. If it doesn't then pick up a MH the same wattage and add that to the center.

You could always pick up a 1000W and a killer bulb that covers the spectrum but that would not cover as much area because the source is one place. The difference is the 1000w would have a penetration power of about 3 feet but only in a four foot area. With 2 400w sure you would have 18 to 24" penetration but you can cover like 6 foot square.

So it depends on what you want to do.

my areas are 30" wide by 5,5 long. the other is 3x3 if i put another hps with hood they will be butt to butt after conexted to the vent the other area it not enough room to hang two lights of that size with hoods

Whoops, I just recorded it and posted it. LOL I see what you mean now I watched it.
Well, as I was backing up I knocked a full beer off the table, the thing spurted all over the wall, floor and back of my chair.
What a mess.

Humm, not sure how to edit a video yet.

Temps 86 res 67°
PPMs 390
Ph 6.4 back to 5.7

We got another inch of growth, It’s about time to start training.

I didn’t realize how strong the root system is. I looked at pictures and it looks like spaghetti.
I guess I figured it was supple like that. It’s not.

Here are some root shots at 30 days in the tub. I just don’t see me vegging a root system this size
then pulling it through a 2” hole. The roots bottom out and spreading out all around instead of following
the water back to the drain

I have never handeled roots in a grow. Do you think I could just squeese them together like I could
the canopy without too much damage?















Now I see why aeroponics grows plants faster. Look how the water follows the root to the tip.
