Hello and help

[RastaFire]

Ok so I'm thinking I'll get a coir brick or 2 and maybe some perlite to mix equal parts coco, perlite and that soil I have already.. Or get pro mix HP mycorizzhae and use that. Is that the right HP mix to use? Are those compressed peat blocks any good for cannabis? Would soil and coco be enough without the perlite?

There’s all kinds of stuff. There’s new coco blocks that you plant right in the block. Sweet huh!

You should go with whatever is closest to real soil, as it leaves less room for error.

I regularly see new growers on these forums having problems with their plants growing in coco coir.

I am sure the medium is useful for people who really have everything dialed in, but it seems to be more finicky with watering and nutrition for beginners.

Soil is more intuitive, especially for folks like me who had experience with other plants before being able to grow weed.

It seems like the pro mix hp has alot of coir in it, not sure if I should mix the soil i have with coco or mix coco with a different potting soil or just use hp, but the hp doesn't seem to have nutrients in it? I wanna use soil but don't wanna go to composting extremes rn or use bugs in the room it's in, not sure of ways to deal with pests if they occur later.

I was referring more to growing in pure coco coir, which seems to cause problems for beginners though I am sure some people do it successfully.

Try growing something cheap — like tomato seeds — in different cannabis-oriented soils to get a hang of the watering, etc.

Yep. They're called that here too. We used to go "to the co-op" to get things when I was a kid. Just outside Hamilton, so pretty close to Toronto.

I grocery shop at a co-op. Lol.

I would do coco if your going to do coco. But I’m going to let you know that I think it would be easier for you to grow in Pro mix HP. It is very forgiving. And yes Pro Mix HP is great. You can use that or pro mix hp cc is what I use. It has coco in it. I just made a switch to coots but I can tell you pro mix will be a simple grow.

I started with hot peppers. They have the same growing conditions and nutrient requirements as weed (in veg), and are just as sensitive to over watering.

Does pro mix hp have nutrients in it?

 

[Reave]

Does pro mix hp have nutrients in it?

No it does not. Completely inert. Well there is dolomite lime in it which has some calcium I think. It sure if it’s in a form the plant can use though. You would need to feed your plants with nutrients right away.

 

[RastaFire]

Why would pro mix hp be better than coir then if they both are "inert"? Is pro mix just better for ph or something?

Yes, like I said it is very forgiving. The dolomite lime buffers the PH. Also I never said it was better just that it was easier.

 

[RastaFire]

Ok cool, but easier only because of ph? What does the added mycorizzhae do for the plants/ soil?

Yes “just” for the ph. I think they say it’s for roots but in a synthetic system I don’t think it does jack. Pick something and try it then you will find out.

 

[Reave]

Do we need to pH adjust our nutrient solutions? this thread is interesting. (In regards to pro mix)

Mycorrhizae help the plant absorb nutrients that wouldn’t otherwise be available to it. The fungus basically acts as an extension of the root system — a symbiotic relationship.

Does the mycorizzhae attract fungus gnats?

 

[Grandma Weedstein]

Not as far as I know. I think the soil mix with mycorrhizae contains a bacteria that acts as a biological pesticide.

 

[Reave]

There is a KiS organics podcast that speak about mycorrhiza, it’s one of the first episodes. Dude says he rolls his seeds in mycorrhiza but need to be careful of too much other P or K can’t remember. The whole series has been pretty good I’m like 4 or 5 episodes in.

I'll second the suggestion for Black Swallow Soil in Brantford. They even have their own soil mix ready to use. Don't know about shipping costs though as they ship via CanPost or if you are local, they do have pickup service.
