I plan to have straight water in the res and periodically handwater with liquid karma and pureblend pro (after a few months) to keep it interesting and use up stuff that I plan to not replace. Any ideas as to the shelf life of pureblend pro products? Hopefully I can keep up the same growth rates as I got in coco and use less water (= less work!)

very simple method:

*perlyte, or coco, or 50/50 coco/perlyte

*1 tsp osmocote / 5 gal of coco/perlyte

*1 tsp humic acid

*no peat (sunshine or pro-mix)

*no worm castings

*no biotone

*no oyster shells

feed regime:

*1 tbsp (15grams) 5-12-26 (jax) + 1 tbsp (15g) cal-nitr8 + 5 gallons h20
*edit*
(npk-mg preferably mixed in different tanks & fed from separate from ca++)

*hand-water, @ 1X / day, until very little run-off. then stop. in 5 gal containers, 1 / 5 volume of container / 48hrs, max.

*5*128 = 640
*640 / 5 = 128
*128 / 2 = 64
*64 = 2 liters per day, max.

maybe start w/ only 1 liter (32 ounses) per day. should still be run-off. 1 1/2 - 2 liters when canopy reaches 3x3x3+.....

should be able to feed that same amount (ferts) thru the entire season

shelf life of pure blend pro depend on a lot of thing , the way the store keep is temperature is a factor key . i have a whole gallon that went bad on me less than 4 months after i open it .

i find out the store where it came got several hydro wheel crap on display and the temperature in the store is always over 35 and i was shocked last summer ...i wasn't barely able to stand in the store, it was a like a steam bath ...i was sweating bullet and my clothe where soaked in less than 10 minute ... so i find out that was a main thing to consider if the store is keeping a few 1000 w without ventilation ....they are not unique , too many store are the very fucking same =high temp all over

no wonder their nutes went bad .

thing was , my friend bough me the gallon from that store ...i found it came from that place....

now i note that too many hydro store got bad temp in their store ...nutes bottles in plain sun and at night they baked under hps ...

no wonder some nutes precipitate in the bottle only a few day after being opened ...

my gallon of pbp was gazing bad ...it was ridiculous after 3 months , it was like opening a pepsi bottle...the pffffffffttttttttt sound....plants went pretty bad too ...

using maxibloom now , 1 tsp and voila

this is a great thread, thanks carl. after fatman's chem refresher courses the 3 to 2 jack's to cal-nitrate is dead on for that 3-1-4 for sure and way easier than mixing all that shit myself. i didn't really want to buy another scale to measure that tiny amount of ammonium molybdate anywho

This is an egregious bookmark, and thanks for the research and links!

Thanks carl for the thread and mistress for breaking down the info! Sweet!

Eight weeks and change..



I cut out the calcium nitrate after 6 weeks. That was a mistake. The leaves are yellowing out nicely and I know from experience it will lead to a very, very white ash but...the edges of those yellow leaves are a little on the crispy side and there ain't no way that is good for a plant...live and learn.

I will post some closer pics when I harvest so you can see crystal development...but I would be willing to put it against any hydro store nute, at least grown by me.

Instead of the Potassium Silicate, could I add Diatomaceous Earth instead? I know that it's high in silica. and I've got tons of it already. Also how long can a mixed batch sit for? They're inert chemical compounds so I'm guessing indefinitely? Plan on mixing up 5 gallon bucket batches at a time for my upcoming hand watered coco grow. If the buckets are kept with a lid on in a cool dark dry place, will they be okay to use for a week at a time? thanks.

Thanks as always but my point here is to produce some babies without having to mix any nutes. They seem pretty happy so far, we'll see. My little ones in 12/12 with nothing but pro mix and osmocote are looking very frosty and healthy so maybe I should've just stuck with the oc+ and skip all the other stuff but you know what happens when you have a bunch of carp laying around!

I maybe totally wrong, but I don't see why there is a discussion about EC. The plant takes up a certain amount of salt per unit of time and the same goes for water. Why wouldn't you just aim to figure that out and give it what it needs?

For example, I have a DWC plant. The EC is say 1.8. Tomorrow there will be a little less nuts and water. If the EC goes up, the plant needed a bit more water, down and it needed more salt. I am to find where it become stable. Genetics, CO2 levels, lighting, and temp have a lot do with this.

I have noticed my EC must be much higher the day they go from the veg room to the flower room due to the lights (more of them, less crowding). If I don't change my nutes the EC will slowly start dropping. It may stop at some point, but from what I know the plant will need to expend energy and work to get the salts if the solution is too dilute.

I have heard the term 'steering EC' in greenhouse literature. That makes sense and seems scientifically the most sound.

Anyone disagree with this? If so please let me hear your side, maybe I'm just missing something.

My flower room takes a EC of 1.8 and I have no runoff ever. The water that collects in the wicking area is 1.3. I am trying to get it to go up, but don't want to make an over correction and cause damage. I will raise my EC slightly until I see that number climb. It should climb slowly. But it seems like right now they are consuming more salt than is in the water.

let me end my saying I am aware there are studies that make a case that the sweet spot is large, I'm just trying to find what is best for the plant, but it may be negligible.
