Is this the right Pro mix?

Hey guys I just bought this pro mix pack

PRO-MIX Moisture Potting Mix

Ready-to-use compressed 2 cu. ft. potting soil is perfect for all indoor and outdoor container planting, re-potting or seed starting.
www.promixgardening.com www.promixgardening.com

I wanted to know if this will work well for my grows.
Im currently in the middle of the grow and will be transplanting from 2 to 5 gallon soon.
Is this good enough on its own or should I mix it with some more of my other soil?(Kellog's Organic Potting mix, cheap home depot soil)
  • Sphagnum peat moss (80-90% by volume)
  • Coir
  • Perlite
  • Ground Limestone (for pH adjustment)
  • Wetting agent
  • Mycorrhizae
Is there anything bad about it?

I have pro mix hp M, but I wouldn’t recommend using it alone. Either bottle feed Nutes, or amend soil.

Promix BX, and HP are the 2 best. 3.8 cu/ft bales.

I agree, only because I prefer inert medium. I like to feed my plants the nutrients I choose, when I choose to. I've switched however from Promix HP to Sunshine #4. I can get it in the same bale size (3.8cu/ft), but it's $5 cheaper. It's essentially exactly the same thing.

It will work just fine. I wouldn't mix anything in with it. This Promix is soil-less, so you have to treat pH differently than soil, so I especially wouldn't mix soil in with it.

That Promix also has nutrients built-in, so don't feed the plants after transplant until they tell you they need it (likely a couple to three weeks).

With peat based products such as this one, pH your water and water/nutrient mix to 6.0 before watering.

As far as nutrients? I've used General Hydroponics Flora series for several years. I'm currently phasing that out and switching to Jack's 5-12-26, Calcium Nitrate, and Mono Potassium Phosphate powdered water soluble nutrients. That'll be a few months long process though so I can dial it in over a several plant grow in my experiments environment, before I use it in my production tents.

The medium itself (both Promix HP and Sunshine #4) contain Perlite. When I first switched to Sunshine, I added some extra Perlite as I felt it was light on it, but quickly realized that the water retention was too low, so I stopped that practice.

If you ever bored and want to try some cheap jacks that gives amazing flavor use jacks classic blossom booster for flower cycle. Go by Ppm. Up to 1000ppm I go sometimes with it. Plants love it.

The bloom booster has some K and P (Potassium & Phosphorus) I mentioned, but it also has several of the micro nutrients, along with the third primary macro, Nitrogen. It's more of a balanced mix, whereas the MKP I'll be using has only Potassium and Phosphorus (0-52-34), with nothing else.

Essentially, when/if I use the MKP, I do not want to be upping the quantity of any other macro/micronutrient other than just those two specifically.

Edit: I just realized you may have meant to use *just* the Jack's Bloom Booster in flower. If so I misunderstood before I wrote the above.

I have a bag of this running now.. placed a couple of clones in it.. I believe it was .30-.10-.10.. if I’m correct it says feeds up to 9 months..I’m just testing it out..seems ok.. I believe I need to drop the ph.. I assumed the limestone adjusted it to 7.. however, with all the peat.. make sense now to water at 6..

The BX with initial watering usually measures around 5.8, and then after a couple waterings will stabilize at 6.2

Yea I actually didn’t want to deal with ph just yet I was trying to go towards organic living soil route. I can’t find a local source of ph meter and organic ph up/down. Anyone have ideas?
i think I’ll just return this mix lol

A 4-1-1 is very low on both Phosphorus, and Potassium

Weed likes the same amount of Phosphorus as it does Nitrogen, and 2x the amount of Potassium as Nitrogen, and Phosphorus.
A 1 to 1 to 2 ratio is best going by tissue analysis.

For chemicals we use Chem Gro fert, which gives a 19.5-20-39 ratio. Or 1-1-2

The Kelp is also really good.

For organic I like Peruvian Seabird Guano. Both Veg, and Flowering formulas. In veg I like 2 parts Veg to 1 part flowering, and reverse in bloom. 1 part veg x 2 parts flowering

I also like to supplement Kelp, Oyster Shells, Azomite, Wood Ash, Bioactivator

Each transplant I also add dry fish fert spike that are 6-4-6 but they must be slow release. I’m trying to do organic on a budget lol can I use organic tomato fert?

Tomatoes have a close to the same ratio as weed. Just depends on the ratio. Try and get the same amount of Nitrogen as Phosphorus, and 2x the amount of Potassium.

Weed is also a heavy feeder of Magnesium, and Calcium. Mg is the #1 deficiency in container gardening. Oyster Shells are a very good source of Mg/Calcium. I also recommend Azomite, and Kelp for trace minerals, and growth stimulators.
