Jacks Hydro 5-12-26 vs peters 5-11-26

[Budley Doright]

So some weeks back I was in the big city and tried to find jacks hydro.....

the dude says....

we don't carry that brand but we do carry the peters brand.....


So ok..... I bought a bag..... still a bit skeptical I diligently compared the bags.....


The micronutrient package is exactly the same...... not much to say there....


Except for magnesium.....

Lets return to that in a moment.....


The macronutrients are pretty much the same.....


5-11-26 vs 5-12-26 jacks has slightly higher phos than peters....

which is probably not problematical.....

Both are supplemented with calcium nitrate......


the biggest difference therefore is the magnesium......


Its widely reported that with peters magnesium def is not an issue.... because jacks contains high levels of magnesium.....


After considering the labels my general focus has been..... does the use of peters and the lower amounts of magnesium result in any sort of magnesium defs.....



Of course one of the main things about jacks and peters is that they seem to do quite well using tap water...... within reason of course....



tap water will contain calcium and magnesium.......


while I cant say for sure ..... when using RO water.... with tap water the peters has been fine.....


I do in fact keep some epsoms salt just in case..... but the plants haven't complained to this point....



Ive been using around 600 ppm and the plants look perfect.......



I have been doing res changes every two weeks.....


at about a buck per 60 gallon trash can..... cant beat it.......



My motto is something like....


low ppms..... and dump the res regularly.....



Anyone else have any comments about the two ferts????



I certainly cant say which I prefer..... but for me the peters is doing just fine......

I use Jacks and do not dump the reservoir ever, just keep topping it up. No issues at all. I do an automated Hempy top feeding daily with a good volume of solution. I do add a 1/2 teaspoon of epsom salts per gallon of solution. Actually it is 12 teaspoons of each element per 27 gallons. In tap water.

Im a little puzzled.....

I believe hempy is a drain to waste system......


why would it be necessary to dump the res?????

Burnt Rope, I believe Dr. RedWhite was referring to a larger rez that he feeds his individual hempy's from with an automated drip system.

Dr. RedWhite, how do you like that auto hempy set up with Jack's? I'm running the 3/2 ratio without epsom salts, don't think the extra Mg and sulphur is needed.

 

[Budley Doright]

I get a little confused because I run a sort of bastardized hempy myself.....


The standard hempy is for hand watering..... and a little runoff..... drain to waste....


I fertigate every couple hours.....


but recirculate the run off.......



Like I say its pretty bastardized but its closest to a hempy......


Doing drain to waste you don't need to ever drain your reservoir.....


when doing a recirculating system ..... reservoir management is in order....


Im also using turface the forever medium......


Turface looks like perlite anyway......

I know you didn't ask me....

but Im using peters not jacks...... peters has half the level of magnesium that jacks has.....


Im seeing no issues.....


If I were you I would only keep the epsoms on hand just in case you see some magnesium def chlorosis.....


The only way I can imagine getting magnesium def with either is when using RO water....or rainwater.....

 

[Dr.RedWhite]

I haven't run Jacks without epsom salts. I think the extra sulpher is a good thing and I have never seen any problem with running high levels of magnesium sulphate. I never thought that returning the runoff to a reservoir and using it again via a timer and a pump might be bastardizing the Hempy just making it automatic. As for growth and beautiful plants I am there in spades. I only do a couple of runs a year but I do not dump or clean it until I am done for the year. This could be 6 months of just adding mixed solution never letting the res go dry. My 1000 GPH pump runs once a day for 12 seconds and my buckets are a bit more than 3 gallons.

 

[Dr.RedWhite]

On a new point I generally add a mixture of Humic acid at 1/4 tsp per gallon and 1 tablespoon per gallon Maxicrop seaweed juice the last four weeks of flower. I to this via a 32 ounce cup once a week. I was also adding 1 1/2 tsp of Molasses but feared my res going biological on me. And Burnt Rope I am still very happy using the Walmart cloner. If I had to complain it would be that taking more cuttings to make sure I have enough always causes me to have more than I need!

Jacks and Peters are practically the same thing. If you look at the history of J.R. Peters Company I think you will find they are or were the same folks. Very helpful and they do nutrient analysis and leaf tissue analysis also. They will help you directly with any needs you may have. Very nice folks.

Hey guys, I decided to go with a 5gal dwc system kit, 5 buckets and a small 1 gallon cloner. I was wondering, I plan on going with W.W. xtrm from the AMS bank, and maybe MOB from rcmc, so I was wondering which Jack's should I go with for a simple, effective grow? I only want personal smoke, I'm no where near a comercial grower, (yet, I want to open up a small dispensary as soon as the laws change, hopefully next year). I'm on a budget so Jack's is perfect for me atm.

DWC can be a rodeo with trying to keep your solution at the right temp but I have seen some awesome plants come from it. I might do a run with some cheap seeds to work the kinks out while getting the system reliable. As to which Jacks I can't imagine them being different enough to make a difference.

get a chiller and go with better seeds. $10 each or more... you will concentrate better and whatever comes at harvest will be 'better' too.

and learning how to clone, successfully.. it isn't as hard as many say. I didn't know how in the beginning and lost a really great tasting, high yielding, knock your socks off, endless high Big Budda Cheese girl (when he did regular seeds). it sucks when that happens.
