Organic Good?

Bubblyjim · 06-30-2002, 03:46 PM

Hi Peeps,

I just re potted my 9 week old plants into organic soil.
They were in a normal commercial compost previously (Jon Anis No. 3).. but were starting to get root bound...

All my local garden centres can't get hold of the Jon Anis 'cause there's a production line prob or something.. so I had to change.. and decided to get this organic stuff..

It is much lighter stuff in weight than the original compost. I have put 2 inches of gravel / stones at the bottom of the medium, mixed the compost with vermiculite and perlite and got them in 12 by 12 inch pots.

Just wondering if there is anything I should be doing different.. they seem settled in, and seem to be ok..

Do I still use nutes?.. or should I hold off for a couple of weeks 1st... any general advice would be greatly appreciated...

thanks

Jim

I'm confused. You said you switched from compost to organic stuff, but compost is organic. Can you give more detail about what they were in before? It wasn't pure compost was it? Compost is a soil amendment rather than something to use alone. Are you wanting advice on organic nutes? What kind of nutes have they had so far, and what stage of growth are they in?

Hi Brindie,

Sorry.. yep.. it was all in Jon Anis no 3.. which is a heavy compost which is a soily compost high in nutrients and quite dense.
That was all I used.. I never mixed it with anything.. it was just compost. (I have a feeling you are going to tell me that, that was a silly move?) I never had any Vermic' nor perlite.

Nutrient wise.. I've been using a high N nutrient.. I think it is 9-4-4 with all of the secondary nutrients too. they are at about 10 weeks now.. and are ready for flowering.

This newstuff that I have bought sacks of states on the bag:

"An all in one peat free compost for garden and house plants. Especially recommended for pots and containers. This organic multipurpose Compost is produced from composted bark with additional nutrients including trace elements to ensure vigrous healthy growth of plants at all stages and moisture air and nutrientsaround the plant roots."

I have planted them all in 70% compost, 15% Vermic. and 15% Perlite, with gravel stonesat the base of the pot. Because I have just flicked over to the flowering cycle I want to give them some high P solution.. I wonder if this is advisable.. or should I wait a bit 1st.. because of the nutrients already in the compost... and finally are you going to tell me to take my head out of my A$$ and go get some soil? LOL.

Thanks
Jim..

High Jim.

Compost should really only make up 10-20% of your mix. I'm surprised you didn't have overwatering problems using pure compost. Marijuana likes a very loose, airy medium and as you noticed compost is heavy. I think you should add some soil and more perlite (up to 50% of each). Especially with organics, there's no need for vermiculite. Your 9-4-4 with micronutes fertilizer sounds good for getting them this far, and yes you should look for something higher P now that they're flowering.

Cheers Brindie...

Is it wholy worth repotting again at this stage?

I have just moved, which shocked them... then I repotted about 2 days after..more shocking.. and now they are in a different environment.. although the equip. is the same + I havechanged their medium to this light and airy (tree bark) compost.. and finally.. I have just flicked them over to flowering (3 days) do you think I should go through all of the motions again seeing as their growth is good?

I'm not being lazy... they just seem to be doing well since the repot.

I'm just concerned that if I put more P in.. I could over fertilize due to them being repotted so recently..? would you leave them for a bit before adding the nutrient.. or are you more brazen than that?

thanks for the advice.. is well appreciated this end

Cheers
Jim

PS.. Seeing as I started in pure compost and I expect the moisture levels did get higher than ideal.. I wonder if the off spring of these plants (seeds) will have better moisture dispensation capibilties seeing as their parents have had to go through it... but survived.. hmm.. I'm pondering

Sure you could just leave them alone unless they show symptoms of overwatering or other problems. If it's not broken don't fix it huh?

I'm just surprised you haven't had problems thus far using so much compost.

I don't start higher P nutes until they're a couple weeks into 12/12. But you should look for one that's maybe 1-2-2 ratio, hopefully with micronutes like your vegging fert. They may not need a lot added because compost is rich in nutrients.

It is possible that you have a strain that can survive in denser soil than most plants, and if that's the case at least some of their offspring should have that trait as well. If you selectively bred them you could probably increase this ability, but personally I think it would be easier to just use lighter soil.

Now there's a reply I enjoyed reading.

The only thing that I have noticed (different) since repotting, apart from better growth.. is that all of the new growth and the top of the plant has turned a very bright and alluminous lime green colour.

My guess is that it is prob the ferts in the compost doing their work.

Cheers for ya help Brind.
Much appreciated,

Jim
