Promix and bottled nutrients question

Robgrows · May 23, 2025

Hello fellow farmers.

I am a retired small time grower from Southern Ontario. I run perpetual for myself and 2 adult children.
I grow for taste and effect and prefer older strains like Girl Scout Cookies, Pineapple Express, Purple Kush
and various others. I need variety and have something for whatever mood or time of day.

I run clones in a combination of Happy Frog/Ocean Forest and perlite. I use the FoxFarm trio with some
cal-mag and silica. This has been working well for years. Until now. Getting the soil has become difficult
for about a year and now nobody has it.

I'm going to try Promix as an alternative. In my small flower tent I will experiment with dry amendments.
Hopefully I can lock it in with a couple of test runs.

Most of my strains run for 63 days (p/e 71 days) alternating feed/water and just water the last 10 days
or so.

Promix is a different animal. Will this schedule work in this medium ? I have scoured the forums/YouTube
and haven't been able to find a definitive answer. I could try the feed/water (probably will) or feed/half feed
if the first doesn't work. I know my plants so eventually I will figure it out.

This question is not about the nutrients themselves as we all have our reasons for using whatever so lets try
to avoid that conversation.

So farmers, if you are growing with Promix and bottled nutrients let me know how you feed our beloved plant.

Thanks in advance.

Gosh you just made me feel like a dinosaur with the Girl Scout cookies being called a old strain

All the best bud

Hey whats up @Robgrows and Welcome

Im a Promix user for life and its super easy man. At times I run organic bottled nutes, but mostly use Advanced Nutrients. Indoor Farmer hooked me up with some teater dry amendments (Bokashi) I believe, and I did add some last run. Unfortunately ran into PM and tore the basement down, so not to familiar with the dry nutrition method
I usually run Advanced Nutrients at half the suggested dose, and rarely ran into any lockout or nutrient burn

Im in the KW area bro!!

Ok maybe not quite old school but I think I first had this about 20 years ago ? I've had my cut for about 5 years.

Panama Red, Columbian Gold and the dreaded brick weed whatever that was. Those were from my teenage years
in the 70's. Those are old school.

Cheers

Just up the road.

Thanks for chiming in. Ok so this is what I'm looking for. So half dose. Every time or do you alternate with just water ?

I run ProMix HP with well water and Mega Crop one part (Greenleaf Nutrients)..

MC is an inexpensive dry powder and I feed every watering by weight.

Two SIP's and a hempy !

Cinderella 99, a bit hot @4.5g/gallon

Destroyer

Panama

I keep it basic....half dose every feeding. I only use Advanced Nutrients Grow and Micro during vegetative phase. Then switch to Micro and Bloom for flowering. PH'd to about 6.2
If plants are growing quickly and start packing the bud, I do add Big Bud (half dose) for a couple weeks

It was just a joke my well it sounded funny in my head

Interesting that gsc is about 20 years old guess time flies

Glad you got the information you was asking about

Enjoy the adventure and all the best bud

Grew some c99 a few years ago. I liked it but the kids didn't.
Never heard of Destroyer. Had to look it up. Does it really take 12-14 weeks ?
MMMM Panama.

Thanks for the info on Mega Crop. I'll have a look.

Funny the things you remember from almost 50 years ago.
I was lucky that I always had a reliable source or 2.
The Columbian Gold really did have a beautiful gold color.
Panama Red code named "Little Red Haired Guy" had beautiful red hairs.
Brick weed needed an album cover to sift the seeds.

What were they really. Who knows. Never heard of Sativa or Indica until decades later.

Thanks again Greenadian. I'll be trying the half dose every time.
I'm thinking of a side by side using 2 strains 2 plants of each. 1 dry 1 bottled of each.

Judging by the fact the Destroyer took longer to even start flowering and how slow the buds are building I would say that estimate is going to be close

BTW > I did a few grows with AN ph perfect and found that anything over 1000 ppm burnt the shyt out of them. I backed off to 900 and was able to pull +13oz from an Early Miss Auto using a 600w MH/HPS in a wing reflector

But I quickly got tired of measuring out mls of six different products !

With Mega Crop one part you measure one part of powder by weight/gallon, done... And with ProMix HP it is not necessary to adjust ph !

I have compared AN, GH Maxi Series and Mega Crop one part and all of them performed equally well !

So for ease of use and Cost it came down to GH Maxi Series or Mega Crop one part. IIRC the MC worked out to be less than half as expensive as the GH and much less expensive than AN.

Again, IIRC it cost me ~$150 for AN to grow three plants with enough left to do four more. ~ $20/plant

I purchased a 25# bag of MC for $120 four years ago. I've grown 27 plants since then and still have about 4# left

~$3.50/plant

Cheers

Thanks for all this info chuck. I have time now to put a plan together because this happened. Still hoping others that use the bottles will chime in.

What happened to the ProMix HP ?

Those bags are a completely different animal

This will always be my go to until it isn't. There was a Canadian blend from Quebec I think that was almost the same except it didn't have
the bat guano. It was cheaper but they discontinued it about a year ago. Now it can be weeks between restock.

So I'm good for now but moving forward who knows.

Now I have time to properly plan a side by side grow with Promix and bottles/dry amendments. Now that the pressure is off, I'm really
looking forward to doing this. Probably won't start this until September but I will update when it happens.
