I'm in Ocean forest, clone and veg out for moms to take clones. No flowering, just veg. The above is the cheapest kit I can find for jacks 321.

If you think you'll end up using it for more than one cycle I would suggest just getting the large bags and getting epsom salt from Walmart or something.

It's about twice as much, but like 11 times the amount lol. The jacks epsom is WAY overpriced, pretty much all epsom is sourced from Giles and relabeled. I get mine from Walmart for like $6 for 8lbs.

I would only feed 4x max per mom cycle. Ffof nutes hold my plants over for a bit. I swap moms out 2-3x a yr.

I've actually ordered my jacks through them before. great experience with them when I had a shipping issue as well.

That web site has some good deals in their dank deals section too 👍

If you contact j r peters email(info@jrpeters.com), they will send you a link to a page with all their affiliated dealers. I had it somewhere but can't find it right now. Anyway, I was pleasantly surprised to learn that a lot of "regular", IE non-cannabis gardening stores are JRP customers and if they don't stock what you want, they will often order it. As you likely know, non-weed places generally have lower prices.

I contacted a very old-school, straight-laced place near me when I was in the city and they were happy to order Jack's 5-12-26 for me.

Hope this helps somebody.

It's still pretty much a secret in my area, and I'm leaving it that way

Secrets out





Bit of sticker shocker there, still , looks to be about 6x less $ than what I am using now.

Did you recently find a better price @Amarok ?

Did you recently find a better price @Amarok ?

No. I mentioned that I had reached out to local companies back when I bought mine and found that many would order it in upon request. That was a number of years ago. That stuff goes a loooong way for a small timer like me.

Seems like it, but when you figure epsom salts are almost nothing and cal-nit is also very cheap, it's more like 50lbs of feed for somewhere around $220.

Metric makes for easy math. Flowering with one gram per liter nets me 1100 litre for 25 lb bag.
I use 3000L per season.
Puts me around 30 cents per finished plant, as opposed to the $2 that I am paying now.

The only thing that concerns me is the N source.
I am using up to 30% ammonia at this point. It keeps the pH lower and helps chew up this hard water.


This is what our riverbed looks like right now, and this is where I'm getting my water.

The only reason they have to A and B all of that stuff, and hide it in prill's, is because of the potential calcium latchiness.

I see they now offer a part A 0-12-26 For flower.

I was at a grow store today and looked for this to give it a try. They didn't have any, so I grabbed a 1kg bag of the 10-30-20 blossom booster to test.

That stuff has a very limited window in which to use it. I bought a 25 lb'er back when. Tell ya right now it's a lifetime supply, lol. I also feel it makes branches and stems both a little more of them and definitely stronger, if you use it for the entire grow. Anything looking weak outside, gets this for the duration. I never used it inside.

If anyone is looking for a dirt cheap bloom booster look no further than MPK 0-51-34, I mix it with some Epsom salt.. Always got great results

Do you use it as a 1 part? It has 0 Ca, so that seems strange if so.

It was an impulse buy, so I'm just starting my homework. I'm seeing conflicting stories, so it's nice to hear from somebody like you that is knowledgeable and experienced,

When do I use 10-30-20 Bloom?

Our 10-30-20 Boom formula is meant to be incorporated into your grow program to jump-start bud production.

"Remember they're designed to be used during the same in your grow schedule, but not in conjunction with each other."

Well, that was awkward.
' You may choose to use blossom booster or Ultraviolet during transition, but not both '

Is that what they are tryna say ?

Just bought my 1st jacks 321 kit last week. 13+yrs of using technaflora nutes, (6 bottles, and 80% more $). Let's see how jacks measures up.

 

[Dino Party]

I got my jacks at growgreenmi.com on thier super sales page. It goes on sale all the time, or at least it used to.

I believe you are correct, I think they are saying that during the 1- 2 week transition , you can use both, but only one product per individual feeding , using the other the next time you feed. Rotating products during the time frame, but not using both ( mixing together) during one feeding .

Yes I use it as a one part. But I only used it a couple times early on. Then I switched to Masterblend Tomato for the rest of the year.

What's everyone's jacks123 and/or masterblend values for veg and flower? And masterblend is only used for 3 weeks after flower has started? I'm reading mixed time frames on different areas.

I've been doing 3.6-2.4-1.1 in veg and 4-2-0.5 in flower and it works pretty good, usually keep it around 1.8-2.1 ec depending on vpd and what the plants look like. Might pick up a bag of the new 0-12-26 to try out soon, the ppm values at 4-3 look a little better for flower than the og part a.
