I'm impressed with the performance of the boveda 320g 62%. I actually don't have anymore bud to hydrate and it's a bit much for long term storage to be honest. 62% is excellent for over dried bud, but I would never use it for storage. Too much moisture for properly dried buds. Maybe the 58% ones are popular for a reason?
The big ones are the only ones that are worth it imo, the small ones don't last but a few days in my experience.
It can take weeks to rehydrate too dry weed with the 62% and personally I've found them very good for long term storage, it really preserves the terps.

Not tried the 58% tbh but will for sure, imo these products are genius.

Jacks is good stuff. I once tried to get a commercial grow to use this as a cost effective product to increase profit margins...Instead they opted to buy 50gal drums of liquid karma and bunch of other non-sense.

They went broke...

I like Dynagro Foliage pro, but my 2nd choice would be jacks pro hydro + the cal-nit

Can someone help me out with Jacks?
I got high ppm tap water 300-400ppn out of the tap. Sometimes worse. PH usually 7-7.5 out of the tap.


what's good for vegging moms and clones
15-6-17?? Do you ever put any food in your cloner res? Ive been getting some yellowing I want to avoid. Would this help? Or would it stall rooting?
do you add cal not to this as well?

and then what's actually needed for flower?
I saw another poster say just the 5-12-26 is needed? Do you add cal nit to this?

Currently flowering with FloraFlex and really like it so far helped straighten out some cal mag looking issues fast. But it also is really expensive compared to Jacks.

Edit: also just really like the simplicity of A+B deal. Jacks should be the same just plus Epsom salts?

well that info would have been good to know. lol.

i use jack's RO formula with my well water 0.2EC. i had issues with jacks tap. 1 part . just a FYI as an alternative to 321
so for VEG it's Part A 5-12-26 + Part B 15-5-20 TAP (if I wanted to try straight tap water instead of the CAL NIT?
DC4BECEF-D7DF-4611-9706-8CDB1EC6FF91.png

and for Flower it's Part A 5-12-26 + Part B 10-30-20 BLOOM?

is that correct? And do you skip the CAL NIT?

Part-A 5-12-26 is normally used in combination with Part-B 15-0-0 calnit.

The bagged 10-30-20, RO and TAP are one-part. Optionally, or as needed, calnit can be used with these.
So if I understand correctly. For VEG all I would run is 15-5-20 TAP and cal nit if I see a calcium deficiency?

and for Flower
Just 10-30-20 plus cal nit as needed?

Tap or RO, many run the 5-12-26 + Calnit + Epsom. Aka Jacks 321. For veg and/or flower.

Personally, I would only use the tap formula if I had a PH stability issue with Jacks 321.

Some run the same formula/ratio start to finish.
I'm trying the bagged 10-30-20 only for the first 2 (to 3) weeks of bloom this run.

Just some common nute profiles, broken down into elemental ppm. (bagged tap formula not on this - yet)

I was curious....added bagged TAP breakdown, at 3.5 grams per gallon. I don't list them, but the bagged TAP includes micros. (with zero Ca, you really gotta be sure enough Ca is in your tap water)

No. Here is the feeding chart for jacks tap. Essentially you are running jacks tap the whole cycle. The bloom and finish are not necessary. I too was confused when switching. So much that I wrote an email to a jacks rep just to make sure a veg and bloom formula weren't needed separately.

Shit never ends in the garden man. I swapped out both my carbon blocks, prefilter, and DI resin. Fucker is spitting out 4-5ppm. No good. Spending another unplanned $50 for 2 new RO membranes on amazon. They'll hit Thursday and will be installed ASAP. How I was able to zero in on the membranes as the culprit is because all other filters have been swapped. This increased the rate of flow through the RO system dramatically. The RO membranes just can't keep up. Also, when the membranes are going out on ya it will trash your DI resin extremely fast on the final 5th stage of filtration. DI resin is a pretty ocean blue when it's all good. In under 1 month half of it has turned sludge brown. Another sign of that the RO membranes are failing. Here's a pic of the 5 stage system. It's basically a prefilter, 2 carbon blocks, the 2 RO membranes, and then finally to the DI resin. I gotta split before the DI with a flow regulator that goes to my kitchen sink and a 1 gallon pitcher in my basement near my garden work area I installed a float valve on. Who the hell wants to walk up stairs for a water refill. Not this fucking guy. That's for sure :)

Laundry cold water tee feeds the RO system. Nuttin fancy. The 2 white canisters are the RO membranes. This is a water saver model so it has a 1:1 exchange ratio. The best you can get for efficiency.

So I asked myself a question today and we're gonna find out the answer soon enough. The question was, how low can I go on ec with jack's 321 that satisfies the plant's needs without using more than is necessary? I'm running 600PPM which is around 1.2 ec on the res I'm making today. I'm also trying out RAW's humic acid. I particularly think the RAW brand is a fleece job, but I bought this shit years ago and thought I'd give it a whirl at the lowest recommended rate of application. 1/8 tsp/gallon. It's supposed to increase the effectiveness of nutrient uptake. I doubt it, but we'll see. If I notice any negative effects the remainder of the bag will get trashed.

I'm doing a major overhaul today getting the flower room up and running. I'm gonna banzai the fuck out of this overgrown critical mass that's way overgrown. Basically I'm just gonna hack the canopy down about 6". Then I'll let it all regrow back as an even lush horizontal canopy. And 6" lower :)

She's a beast:
20210610_094435.jpg

Applying another round of Forbid 4F to mitigate a mite issue. I fucking hate growing in the warm months. Mites are a plague that never ends. All it takes is 1 of those little cocksuckers to hitch hike on some article of your clothing. I change my shoes. I change my clothes. I shower after working outside before entering. Doesn't matter. The fuckers find a way in. After the forbid application I'll be switching to all organic methods using Grandevo CG and Venerate CG. They are safe and effective up to harvest day. Planning to initiate flowering in the next 14 days. Need a little more girth on my other smaller plants. This cycle is definitely gonna be a reduction in size. Not too dramatic, but it will be easier on me and the wife. Last cycle was a real bitch of a process. No encores :)

Here's a pic of the outside garden using jack's 20-20-20 @ 650ppm:

Edited: I mistakenly listed my ec as 2.5. Total brain fart. 1.25 ec :)

Just jack'n it fellas. It releases endorphins and promotes a sense of calm :)

Easy sollution, disconnect the DI stage and relax. You don't need distilled to grow plants and 4-5 ppm is no problem. In fact, DI is corrosive, with zero ions it will leach ions from metals.

Just removed the single phillips screw on all my trim scissors. Ran them all through the shearsharp and they're dam near razor sharp now. Prior to sharpening they wouldn't even cut wax string. Now they effortlessly snip it all the way to the tip. I'd highly recommend the shearsharp. Cheap and effective.

4-5ppm with new prefilter and carbon blocks indicates the membranes are failing. It's been over a year since it was placed into service making 90-150 gallons per week. Factoring in the waste water I run between 180-300 gallons per week. Let's just call it an average of about 250 gallons per week x 52 = about 13,000 gallons. They're due. It only gets worse from here. $50 gets me good for another year at 0ppm. I bought an expensive RO system to obtain 0 ppm water. Anything more is unacceptable. My electric bill is over $800/month during flower. $50 for maintenance on my RO system is no biggie. I'm considering installing bulk reef supply's back flush device so you can periodically rinse the membranes prolonging their life.

I should also mention that once my flower cycle is under way life gets pretty crazy on the day to day work load. I'm dealing with clones, transplants, and a flower room. Plus I still gotta knock the wife around once in awhile and have a sammmich now and then. Needless to say the hours in the day get much shorter as does my patience. If I don't replace the membranes now it'll be 3-4 months from now. An ounce of prevention is worth a pound of cure. I'm a very strong believer in keeping up with maintenance on all of my garden equipment.

Humic Acid doesn't really help much in hydro situations. It's Fulvic Acid that you want for hydro.

Thanks for the heads up. I'm definitely trashing the rest of it. Shit foamed in my res. I literally had to skim it off. I think I originally bought the stuff for making organic microbe tea but I did very badly at growing organically and abandoned that ship quickly for hempy buckets. I occasionally find all sorts of weird shit in my cabinets from that organic expedition. A gallon of molasses the other day. What the hell do ya do with a gallon of molasses?
