I know alot of the regs here use jacks. If someone can please make it simple for me, Im getting into my 2nd grow and I want to try jacks vs organic i just tried. I will be ordering Canna coco, growing in 5 gallon fabric pots. watering from top, using Led lights. Using fridge filtered or tap water that ph 7.5 before i bring it down. Im going to get an EC meter.
what do i need to get to get started and how much of it do i add to each gallon??
Thank you.
2.5 bricks per fabric pot will work. I am str8 coco and jacks only. 5-12-26 A 15-0-0. B I mixed 2 gallons of jacks to hydrate the 2.5 bricks.
I use 3.6 grams A. 2.4. B. 1.2 grams epsom
No digital scale thst reads down to tenths?
A scale that measures grams, TDS and PH pen. Super easy 3 part mix 
I have digital scales.
Im getting the canna in bags.

Yes, i ordered the 2.2 lb bags from jr peters aka jacks for 80.00 to the house. My small grow, 5 to 10 yrs it will last easy.
You mix part a with epsom salt. I heat up some water first. Warmer water helps dissolve the fertilizer and epsom easier. Do the same for pt B.
Good practice, only mix enough for few days.
this is no where near as easy as top dressing every few weeks.
My 2nd grow ever is in progress. Didnt test nothing, just watered for 12 ozs from 3 auto plants. No ph, no tds, no dli.
Dialed light back, didnt water for runoff, did nutes at 80% strength and kept lights back few inches.
We watched and watched and watered.
ok, is there a good video so i can wrap my head around this?? im watering normally in gallon container.
Gram scale is a must for this old couple, 60+ can do it, youll get it.
First, scale
Part A. 3.6 grams
I dont have tenths on my scale
One dollar bill weighs 1 gram. It is 15cms long. 10% of 15 cm is 1.5cm. I cut 6 cms giving me .4 grams
.4 + 3.6 = 4 grams part A
.6 + 2.4 grams B= 3 grams
We old school. An older nickle weighs 5 grams, easy to check any scale for bad battery or altered scale.
Dimes pennies each 2.5 grams
Dollar bill 1 gram
Thats how we made sure we didnt get shorted/cheated.
Id visit J. R. Peters store, web, from the horses mouth.
Not easier just total control. Faster correcting deficiencies as well
Should i order the 4 pounds kit on Ebay for 30? would I add the same amounts to my water each watering? or is there a guide?
Part A 3.6g pr gal. add to water first
Epsom Salt 1.2g add to water second
Part B 2.4g add last
Important to mix in that order if using Silica/ Cal Mag mix in water before Jacks.
Buy whats best for your budget.
I watered by lifting my dry pots, i dont water for runnoff for testing. Cannabis is a weed, it loves dry cycles, depending on the plants age and its appetite as to how much to give.
My runtz is getting a half gallon every two days based on lifting.
The wedding cake, exact same age as runtz, 5wks into flower gets half gallon every day. She drinks more.
I lift them everyday. By the way, neither drink as much as the late summer girls did. Hotter?
I actually did less my first time. 321 like it states.
321 even grams across the board. No nute burn. This time, full strength.
The 2.2# bags lasted me for aprox. 10 plants from start to finish.
The new mix for jacks is 3.7 a, 2.5 b, 1 epsom so you know. I love the dollar bill technique tho, creative!. You can get a digi that does tenths for 15 bucks on amazon if you do not already know. The original is close enough tho lol.
