promix soil or soilless

TokeMySmoke · Sep 19, 2023

Hey folks, I have a question about promix all purpose and ph. I've been hearing that promix is considered a soilless mix. So my question is what should I be PHing my water to? I'm guessing not in the same range as regular potting soil?

I don't like the all purpose mix. It doesn't drain nearly as well as hp and it gave me ph problems. While promix hp or bx can be considered soilless, all purpose includes decomposed forest floor products, i.e. wood and bark humus.

They make a lot of different products some of which do have soil. ProMix HP is the one I've used for about 15 years and has no soil or nutrients in it. With RO water and AN pH Perfect 3-part nutes I can use it straight out of the bale and just soak it down with a nute mix and it's ready to go. Never have to worry about pH so it's a real time saver.

Their Veg and Herb mix grows nice plants all on it's own and has some soil along with organic time release nutes in it but need some perlite added to improve drainage.

You should check out their training centre for lots of great and science based plant info.

I'm liking the pro-mix mycorrhizae hp.

the ph for pro-mix is lower than for soil.
Good luck

Hp is easy to use. If you have to adjust your pH then aim for 5.5 - 6.0 and it's golden. The two types of lime that are in it keeps things on target. With most hydro nutes the pH will drop the pH of your water so if you use tap water that's usually around pH 7.5 it will likely be around 6 once the nutes are added. If your tap water is hard then it's best to use RO or distilled water to prevent mineral buildup in your pots which will cause the pH in the pots to rise over time after repeated waterings. A lot of runoff otherwise to flush out the buildup.

I never have to have runoff using RO and not overfeeding.

ProMix HP is an excellent product so is Sunshine Mix #4 but I would pick ProMix over sunshine due to it being easier to break down the bales. I personally use Coco but ProMix has a huge advantage of holding way more nutrients and water. Not only do you feed less often but less strong so those are huge pros. One reason I went back to coco was I use an auto drain system and the promix was gunking up my plumbing cause its not nearly as "clean" as Coco Coir when it comes to runoff residues.

Doing my first grow with Sunshine 4. Was visiting my Mennonite friends and they was using Pro Mix HP.

Nobody local has Pro Mix but have Sunshine 4. Go figure.

Similar experience in a lot of areas also.

I run promix bx+ and add perlite, i use botanicare pureblend nutrients and calmag and never ph anything. I run 2/3 of mfg recommended dose and feed every watering.

I haven't found any noticeable differences between any of the major brands, Promix, Lambert, Berger and Sunshine. They all grow the same for me if I get the same type, course particle size with high drainage. My wallet decides which one to buy, since a frugal f#$%.

I use HP an ph between 5.9-6.5

Wish I could get hp but can't find that locally. I could order some but the price and shipping is a little out of what I would like to spend.
I appreciate everyone's input.

Do you have an Ace Hardware or garden center nearby?
They can usually order it for you.

I have to go to my local Ace Hardware and have them order it to store and it saves me all the sbipping costs.

Just grabbed a 3.8 cu ft bale of promix bx+ for 50 bucks.

Sunshine #4 Yellow & Black bale seemed way less dirty than ProMix HP, in my experience.

I remember a lot of people complaining a couple years ago the Promix was dirty and full of twigs. I got a few bales like that as well.
If I had to rate them, I would say the Berger BM6 is the most consistent well made product, Sunshine is right behind them and I have used too little of Lambert products to comment.

Try to find an agricultural supplier, they will destroy local retail and ganga shop prices. Professional growers could care less about stuff being geared towards cannabis cultivation. My local supplier hasn't carried Promix in years. They usually have Berger or Sunshine for around $25 per 3.8ft bale.

I just use the Pro-Mix walmart carries. Comes in a red bale for 12.99.
I emailed the people at Pro-Mix to see what the difference between the HP and the regular red bale stuff.
They replied that the HP has more perlite that's it.

Your Hydro shop carry it. Get HP or HP CC. HP CC crushes it.
5.9-6.2 for veg
6.0-6.5 for Flower

I'll look into that. Thanks
