Soil quality matters...

I needed to share this experience, 2 reasons... what I saw really shocked me, and I hope it helps a newbie in the future.

I really wish a took pictures but I just didn't think of it at the time.

So, I am 3-4 grow cycles into this and I've got quite a few things locked in, so I thought it was time to experiment, because isn't that why we do this?? My main goal was to be able to switch to readily available products as my previously selected products seemed to always be out of stock.

I was growing 2 clones in 2 gallon pots and it was time for transplanting to their 5 gallon flowering pots.

I ran out of my good soil mix and the local store didn't have any in stock so I got some $7.99/bag promix, just standard potting soil for house plants.

I potted one of them straight up with this soil.

Then as I was about to prep the other, I remembered I hadn't used any vermicompost in a while so I went to my bins and harvested about 1-1.5 gallons of good quality worm castings.

I put some of the cheap soil at the bottom, then layered in some vermicompost(didn't mix it very well), put the plant in and filled the remaining space with the cheap soil.

About 2 weeks later, I had to go on a 4 day business trip so I (had thought) slightly overwatered both of them so they wouldn't dry out when I left. Well, I come back 4 days later and they are still pretty damn heavy. I leave them for another 2 days and there was nearly no change, still really heavy. This went on for another week or so until I started watering again, but they just didn't look healthy anymore.

Fast forward to 1 month later. All hell is breaking loose, both plants aren't doing well, they look to be suffering from overwatering, and multi-nutrient lockout.

I could figure out what was going on, but my local store brought in some foxfarm soils... I didn't have my good tried tested stuff from previous grows, but this was the next best thing.

I decided to repot both plants.

The first one, which turned out to be the one without worm castings(I didn't label them so lost track) the root ball had barely stretched out into the new soil. I could clearly see the 2gallon pot rootball and not more than 1" of new root growth. This was very apparent as I flipped the pot upside down and most of the new soil just fell out of the pot(not bound to the roots at all).

I get to the second pot, and I found that this was the worm castings pot. The root ball was essentially the same as the first(not really extended past the original root ball from the 2 gallon pot) EXCEPT for the layer of worm castings. The roots were fully formed into the worm castings layer. A big disc shape that extended to the entire width of the 5 gallon pot where the worm castings were. This disc was FULL of roots. There was a very distinct transition between the worm castings layer and the rest of the cheapo dirt.

So... moral of the story, don't cheap out on your soil, it really does make a difference. My ladies didn't even set foot into that shitty soil.

My guess is the PH buffering was outta wack(could be because of the wet conditions which triggered the buffering agent into overdrive) and it made the soil PH out of range of what healthy roots look for, so they completely avoided the crappy soil.

The ladies are starting to look healthier and I'm pretty sure I'll be flipping to flower in another week(2 weeks or so after repot).

Hopefully this helps somebody out in the future.

IMO even Promix "All Purpose" is pretty damn good soil for the price. Most use HP or BX for cannabis. I've used the cheap stuff mixed with a quarter coco and had great results.

Thanks for sharing your experience. I'm also new at this, just doing a second, late grow now. I first started using Kellogg's patio-plus, a cheap wood-based potting soil. Results were OK, but I just had a feeling - with no basis for comparison - that the plans grew too slowly. Nine months to completion, and under two ounces dry yield per plant. Hmmm. Root structure had filled the 10 gal. cloth pot.

This time, I'm trying 2 different media - a good ($$) peat moss based soil, and a coir-perlite mix. So, far, noticeably faster growth as compared to my first grow. Not sure if it will be worth the extra expense, as I'm using sunlight, but experimenting is at least half the fun..........

You ever try mixing peat most into the woods patio plus and some lime to raise the pH back up again? Make it fluffier and still get the positive stuff featured in patio plus

Promix isn't really soil, it's a soiless mix. It has little nutrient value and must be fed with nutrients.
Yes and mianly used and fed like hydro plants on the low end of ph 6.3 it also helpd with ph with the lime and naturally low ph peats

I have to feed mine around 6.5 to make them happy. From my experience 6.3 to 6.8 seems to be the happy area with Pro Mix HP or Berger BM6 HP or Sunshine 4.

Patio plus alone don't have enough p or k for flower. You got to boost it up. Patio plus works much better overall with epsoma garden tone and perllite added. I'm experimenting with it now and it works

Its actually a fine soil as it is, it has come up regular over the years and grown some great pla

I haven't had such luck. The og plant I tested in plain patio plus and perlite grew sloooow and the yeild left a lot to be desired. So I added boosters to the soil and it works better so far. The vegging is rapid. For 1 cubic foot of PP , I mixed in 1 cup epsoma garden tone, 1\2 cup citrus tone, a spoon full of jobes 2-7-4 tomatoe , 1\2 cubic foot peat moss, 2 spoons of lime, and 1 cup of worm castings, 2 gallons of perlite. The peat is to make the mix softer for better root develoment. Hope this kicks ass during flower we will find out

No soil needs all that dude....... :-)

It's more of an expansion. Instead of purchasing a nother bag of soil, I extend my current bag with blank material (peat) that also will soften the rough Woody PP, and more fertilizer, lime was to adjust the pH of the added peat. I already had these items around I didn't have buy anything new

Bag of soil is cheap, its easier, there uae to be quite a few grows in the same stuff with no add ins and great success.

If your confident you know whats what then amend away but its quite a complex subject so if you just read somewhere to add stuff id advise to just stay with the manufacturers mix not try and perfect their science.

If iit works it works though :-)
