Recirculating CSN-17

[MedResearcher]

Anyone have any experience or heard anything about using CSN-17 nutrients in a recirculating system, hand watered or drip?

I think VT tested it out some, and surfingrob as well. Although I couldnt find info if they were recirculating, or drain to waste.

Anyways, any info is much appreciated. Im tired of mixing up the GH, and I think im gonna take the CSN-17 plunge^^

Tks

I've not used it, but you should be able to recirculate any nutrient that balances pH.

I heard the stuff is good, and should be fine in a recirculating.

Yes I actually used CNS in both a recirculating DWC and a recirculating coco grow. It works great and holds PH well even when the plants are feeding heavily. I was using drippers and never had a clogged one in the 6 months I was doing recirculating. Just make sure you mix that CNS up reaaaallllyyyy good cause it likes to stay stringy in the water. CNS like to be stirred for a long time. I notice once I add it into a res with RO in it, the res water will stay cloudy, then when I mix it in more the water will begin to turn clean and clear, with the PH and PPM stabilizing perfectly. It really is awesome stuff and the self buffering is just the tits for convenience.

Tks for the replies guys, I think when I go to the store next time Im gonna pick up some and give it a whirl.


Hey Surfing,

Think tap water with 50 ppm would be ok and not upset the balance of things?

Once you get it mixed into the rez very well, does it stay mixed in? Like after its mixed its a done deal, or do you have to keep mixing it before every watering?

Also did you test any additives with it. Im not big on additives, but like a little Sweet or some Gravity maybe just at the end?

Last thing if you wouldnt mind could you post the PPMs you used at the different stages of growth? That would really save me alot of time, hassle, and worry.

Much appreciated^^

I use CNS17. In this part of the Urban Jungle the ph is up pretty high so I have to use ph down. This leaves the ppm up about 600 with out the Cns 17 added so I at least have to keep an eye on that or it can creep up pretty fast. The plants seem to love the stuff even when you add super bud or spray with bud swell enhancers. It is also fairly cheap.

Nice pile of herb NYC^^

Anyone have there CSN-17 feeding schedule around?

Trying to figure out how much ppm of CSN-17 I should use at various stages of growth.... well im trying to cheat by getting someone elses data

Do you CSN-17 users, feed every watering? Also do you have to flush much?

TKs a ton^^

My hydro store has tons of this stuff on sale right now, i gonna buy a huge jug of grow and bloom to just try it in next years outdo coco run at a buddys house...can't wait to see some more CNS-17 results, best of wishes to you all!!

Im still experimenting w/ the CNS but ive had a few runs with it and my experiences are as follows:

I start off clones w/ about 400ppm, run them in veg for a week or so and start in flower @ 600ppm or so. Right now im experimenting with adding some atami pk 13/14 so Im not totally sure how using additives works out.

Final ppm depends on the plant you are running, I have a sensi star plant that I can run @ 1400ppm and be just fine, but i also have a local clone that is the bees knees that will go dark green and claw up at anything over 700ppm.

So you have to experiment, depending on strain. However id reccomend just starting low, and reading the plants. The CNS is the absolute shit as far as i am concerned, I like it alot and plan to stick with it.

good luck.

Ya its funny, I was just in the Hydro Store yesterday. I ended up buying a gallon of CSN-17 Grow and a gallon of bloom. When I asked them if they still stocked it, they said ya but they thought they were sold out.... ended up they had a couple bottles left

Anyways its funny cause a few months ago they werent selling any of it, and now they said its one of the biggest sellers. The guy who is my friend, and I trust him, told me he did a side by side with tomatoes PbP vs CSN-17. He claimed the CSN out yielded and ripen a bit faster then the PbP. Guess we will have to find out ^^


1 more question

For anyone who has been using it for a while, do you follow the instructions on the label as far as mixing 50/50 grow/bloom during transition. Or do you just do Grow for Veg, then Bloom when you go 12/12 light cycle ?

THis is interesting, it is. Im battleing between Fnova and this stuff and am having a hard time. After some calculations I find that Nova is cheaper in the long run b/c the cost per gallon of solution is cheaper. Nova was 6.75/g and CNS was 9.08/g. Running Nova @ 8ml/g (lucas) and cns @ 20ml.

BUT I just found out from the hydro forum that Nova has a tendency to crystalize if not used fast enough, While CNS @ 18 months hasnt yet. This could be the determining factor.

My local hydro shop use CNS-17 exclusively on all their in-store and outdoor gardens. There demos always look awesome and I am soon to try it as well. The label is more for larger vegetables (tomatoes, eggplants, ext) grown outdoors or in greenhouse which can really handle the nutes. Always let your meter be your guide. The shop guy told me they rock it as follows indoors:

Clones - .4 -.6 ec
Veg - .6 - 1.0 ec
Bloom 1.0- 1.6 ec

Sorry for the late reply but I've been dealing with putting up 2 new growrooms simultaneously and running around all damn day for parts and supplies.

Once CNS gets mixed in it will never seperate, the water will look crystal clear until it stops getting bubbled and builds up junk from anaerobic bacteria (CNS is very very organic friendly, even for the bad bacteria). I've used almost every additive there is with it, I just reccommend backing off the nutrient strength by 1/4 or more to offset the high usable amount of nutrient already in the CNS. I personally still use Gravity and it works great with CNS, gets those nuggets TOO hard actually, I've had people complain that sacks look too small. I use molasses instead of sweet and it works great too.

I usually run 3-500 in veg and 900-1600ppm's in flower. It all depends on the medium though. With CNS however, lower is always better. The great thing about cns is the chemical chelation process. It's always available to the plants, no having to worry about microbials to break it down into a useable form.

I've been getting a ton of questions about CNS, I feel like a Botanicare sales rep

Finally made the switch to CSN official about a week ago^^

So far everything looks good, they seem to be doing slightly better compared to my GH formula I was using.

I got my Veg room on solely grow csn @ 600 ppm ph 5.9

My flower room was just transplanted into larger buckets, and will veg in there for about a week before flowering. So I mixed up the transition ratio 50/50 Grow and Bloom CSN @ 650 ppm ph 5.9

Im hoping to use the transition formula for 2 weeks, 1 last week of veg and the 1st week of flower, then switch to the pure flower recipe.

Do you guys think I should flush them before switching to the flower recipe, or maybe just take it easy on the ppms ?

Also I didnt flush out the GH nutes before I switched, hopefully that doesn't cause any problems. When I water though I probably have at least 30% run off if not 50+% since its recirculating I cant waste it, so the more the merrier^^

Any tips, or critiques are more then welcome.

This is something I posted in another CNS thread just thought that this may be usefull.

Lets get nerd!!
Slurry Technology: from Max Yeild Article
There is an article about 1,2,&3 part nutes and it mentions why 1 parts work so well and how they are able to avoid percipitates. Im going to type from the magazine. This is probly the technology behind CNS17.

It says that 1-parts NOT based on ST are usually short at least 1 macronute due to the difficulty providing a concentration level comparible to 2&3 part nutes. This is mostly due to the relations between Calcium and Sulfate; any meaningfull amount of these two together will precipitate into CalciumSulfate (CaSO4) This preciptate usually canot be homogenized to enable blended dose,OR they form crystalline that also cant be mixed up. (see FNova)

So this can be avoided by using the ST. Slurry is a suspention of mainly CaSO4 solid (which I think is the white shit in CNS) within the solution containing a balance of macro and trace elements. When shaken up it remains homogenized for sufficient time to dispense a uniform dose. Once the dose is added to water and briefly stirred the CaSO4 suspension dissolves immediatly. THe use of a slurry enables the manufacturer to exploit the solubility limits of Ca and SO and squeeze more nute species into a given volume...

Hey guys I am using canna coco right now but I don't like the high cost or relying on an imported product that makes availability a concern, if world events change.

So I am thinking that CSN might make a good nute for me, do you guys think that the transition would work from canna to CSN?
