well the they sure look like they are doin fine on the lineup your given em. bout to do a side by side of the jacks rwdc vs chow mix in dtw so it will be really interesting to see what these end up doing. as always excellent work my brother.

hey TF, those roots look sweet. I'm loving the double trellis. What ec does 2g/gal cal-nitrate equal for you? how about 3g/gal of jacks?

I run 3g/gal of JAcks and 3g/gal of cal-nitrate. If undiluted, it usually ends up in the E1.6-1.8 range for me. What's important is the ratio; if you want a stronger solution, just increase the number of gallons you're mixing the nutes for, and you want less, just reduce that number. So if you want EC 2.0 in your 50 gallon RDWC, chances are you'll want to mix something like 70 gallons' worth of jacks, calcium nitrate, etc. If you prefer EC 1.0-12, then make your mix for 30-35 gallons, then just keep filling the RDWC until the EC is where you want it. If you always mix the different parts of the mix for the same number of gallons, then no matter what the final EC works out to be, the ratios between the nutrients always remains the same.

hey ttystikk, I'm trying to run 3g/gal of jacks and 2g/gal of cal-nitrate, I was wondering what the individual EC of each salt at that rate was for you or other fellow farmers, So I can compare my ec from my pen, as I heard that measuring in weight is useless especially w/ the cal-nitrate as it will absorb moisture and gain weight throughout it's lifetime, that and I have a different brand. I'm not sure 3g/2g of jack/cal-nit will still be 3/2 ratio when converted to EC. I think I need to figure out the ratio EC wise first before I can make an easy 70 gallon batch. I already have stock solutions made up, so I just need to figure out how much EC 3g/gal of jacks is and how much ec 2g/gal of jack is, So I can use as a base ratio to go off of or if my EC is way different then I'll recalibrate my ec meter.
Any help is appreciated.

While it's true that Calcium nitrate is hydrophilic and likes to soak up water as it sits, this generally isn't a big issue unless you live in a damp climate and don't keep it in dry storage like ziplock bags, or airtight containers. I DO use them both by weight; I measure all my materials dry, in grams, and pour my Jacks and epsom (plus amendments that do NOT contain calcium) into one 5 gallon bucket, and my calcium nitrate (and anything else I'm adding that contains calcium) into another 5 gallon bucket.

The point I was making above about ratios is that if you want to run 3g/gal of jacks and 2g/gal of cal-ni, then you always mix them for the same amount of solution, such as 50 gallons;
3g/gal of Jacks x 50 gallons = 150 grams
2g/gal of Cal-Ni x 50 gallons = 100 grams
2g/gal of Epsom x 50 gallons = 100 grams, this goes in the Jacks bucket ONLY!

I fill my buckets first with a gallon of warm water to dissolve the nutes, stir until all the granules vanish, and then top up with cold water. Only then do I pour this mix into a reservoir with cal-ni or anything else premixed in it. I haven't had any trouble with nutrient lockout at all if I do it this way. Now, pour all these, once thoroughly mixed, into your res or wherever. It is only at this point do I use my EC pen and check to see where I'm at with solution strength. As a starting point, you always want your solution strength to be low; so mix somewhat less than your total capacity, and add water until you get to the EC you want. To raise EC, I generally make a mix of 20 gallons' worth of nutes (in my two 5 gallon buckets), then add it to my RDWC, and then only dilute once it's throroghly mixed into the system. Then, I know how much water to add to bring it down to where I want.

Thanks ttystikk, that's the way I'm currently doing things. I guess I wanted a different way to skin the cat, I guess what it comes down to is I trust my EC pen to be more calibrated than my gram scale. I figure if I get ratios right it doesn't matter whether it's by EC or weight, Imo it's good to know both methods.
Also sorry wasn't trying to hijack TF's thread, any sweet updates w/ some more weed porn for me to oggle at?

Hey guys,
been lagging on the updates. I wanted to get some lights off shots, and I always would forget to shoot them when lights just turn off. Got it handled now.

Aerojoe,
Thanks man. I only have measured EC after all ingredients are in.

DB,
Awesome news on the RDWC and chow mix test. That should be fun. Thanks.

ttystikk,
great description on mixing different nute concentrations with varying the water value. That is how I do it too. Only difference I do is three containers of warm water to dissolve in. I also have no problems with the Calcium Nitrate soaking up moisture at all.

Southstreets,
Glad to see you tuning in there man. I will work on getting some close ups. My photography definitely doesn't do these girls justice.

Looking good TrichomeFan, I like how you keep your room so clean. I'm curious about what day and night temps and humidities you're running and what day of flower those last pics are?

Bravo bro! Those budshots are badass... Thx for the lights out shots...
 
#72
Oh, my GOODNESS!!!!! LOL I couldn't help myself; that's lookin' juicy tasty monster good, bro!

TF,
You mentioned you had 19 wifi's. Are all those from seed? If you don't mind sharing what are some of the tricks your learned running rockwool.
Thanks again

Big thanks guys,
Buds are looking out of site! Not too shabby for inexpensive powdered nutes and zone.

resinable,
I keep daytime temps at about 78F and about 74F at night. RH stays between 50-60%. Go Friedrich AC & Santa Fe dehuey!

Those pics were taken at day 52. Flush will start next Monday.

Shady,
Those shots were on your behalf buddy. Glad to satisfy. By the way, how do you focus when taking lights out shots? Any tips?

SD,
Well, I have 18 wifi's now. One was stressed out from the beginning, and went herm bad on me, so I culled it. But yes, they are all from seed. My tricks on rockwool that I learned is to always water to a good runoff, even when they are very small or just transplanted. PH I ran with 5.7 initial and let it creep slowly up to 6.3 before I would think about touching PH down. Most batches, I'd use it up before it went that high anyway. 100 gallons goes fairly quick around here. Don't wait too long to transplant from cube to slab if you are going that way. If the root zone in a 4" cube builds itself to the point of drinking it dry in a day or less, it is tougher to acclimate a big soggy slab to a cube that keeps going dry up top. I have transplanted as soon as 1 week from clone into 4"cube then to slab. As soon as you see roots on the bottom of the cube, you can transplant. The way I see it is the quicker they get into the big slab, the better they are. Also resist watering your plants after sticking them on the slab until they are either almost to wilt, or the whole slab feels fairly light but not bone dry. That is about it from my experiences on this last run.
