The Coco-Coir Experiment Thread

[Guest]

As an experiment, I would really love to see someone fill up a Coliseum with coconut coir. If I only had the money right now to buy one..

 

[clowntown]

I'll try a mix of Canna Coco and Down to Earth Coconut Husk Chips in some sort of ratio, and just Canna Coco alone no perlite. The goal is to hopefully provide better aeration like as if I were using perlite.

Here's what the stuff looks like:





Here's a 1 gallon pot mixed with approx. 1/4 - 1/3 chip brick, and 2/3 - 3/4 Canna.



Looks like I'll be mixing it close to 1:1.

I'm considering also using it straight; this stuff drains so fast (it's like mulch) that I'm afraid I'll have to feed continuously via top drip or something. Might not be a bad experiment for the future, but right now I don't think I have the gear and clones to do that with.

I'm fairly new to coco, but I would like to see the difference in using old coco and new coco.. Right nowI'm on my 5th grow with the coco70%perlite/30 %(large FF) I've read that it reusable up to 3-4 times, but at this point I see no reason to get new. I'll do a side by side when I get some new...

Great idea Anita!! I've wondered about this also....please do a side by side if ya can....

Hey stevr59, that's truly amazing bro....yes I did tag that thread....loved following your grow.....amazing that plant got that big. Thanks for those pics and contributing to the thread

Interesting findings on P/K bones....thanks for sharing that here. Looking forward to more findings on that...

When I make it back I should have something in the works to contribute to this thread

Hey, clowntown, keep this thread goin' for me bro...I think it's an important one

peace

about recycling the coco - its been done for a looong time there is no worries for the plants. 3-4 cycles is no problem as long as proper flushing etc is done.

as i stated above - im flowering my revegged plants in the same coco that they once grew and flowered in before they got revegged. no need to repot etc basicly im talking about more than 6 months of continuos use of the coco. even more should be ok.

i remind again - DONT bring in recycled coco from a greenhouse or outdoors - if u havent sterilized the medium well - this will bring a multitude of bugs to ur indoor. thats the only possible problem in normal cases.

and again i state as in post above - im growing now plants side by side in re-used coco (from indoor) and new coco.. AND there is absolutelly no difference in the plants. basicly - both are virtually behaving the same.

if someone wants to make an other thread about recycling coco (there is allready one - and i think there didnt seem to be much interest actually) it would be great - jsut to make more people aware COCO is a medium that is reused for several seasons in the green houses. we talk about 2-3 years of use!

coco is the most hardy fiber against salty conditions. coco breaks down minimally in that time. the biggest reason for changing the slabs in the greenhouses its the bug control. its easier and cheaper to get new coco once the bug level gets more expensive to control than the coco is to buy.

still the agricultural coco i use is so cheap that recycling it for saving money on the coco is ir-relevant. rather its more for beeing comfortable and not to waste i pay 5 euro for 70 liters of coco.

VT it almost seems im going to start thinking PK is not necesary to give too much of..

rather a program of a little PK - and more bioboost to get the microorganisms and what not to accelerate the process.

i dont if i said it - but im sure PK is more relevant to use in low (read normal - 20-25 celsius) temperatures where the evaporation is not a big problem.

im currently growing in mayor HEAT. im having 35 degrees in my growroom. lower start EC and lighter nutes seems to bring out the better of the plants. and im sure i could have gone even LOWER than the 20-25 ml i have been giving thru flowering.

one thing is sure - this current cycle of flowering i have only given very little PK (half dose on only 2 occasions - instead of 15ml/10 liters for a week as recomended) and the buds are bigger and the plants less burnt than last grow with more frequent PK use.

im aware BIO-BOOST in NOT designed for coco.. but darn it seems to work well!

first time we tried it was in our last years coco-outdoor with tremendous results

only reason not to use it is the really HIGH COST.. 15 euro for 250 cc is outrageous. i wonder sometimes if im the only coco customer in the grow shop.. and they try to make all the profit on me hehe

Clowntown, I've been experimenting with coco mixes for the past few months and have actually not had the greatest results. I've mixed large, medium, and small chunks in with the loose stuff, at varying ratios but somewhere in the neighborhood of one part chunky to two parts loose. The plants in those mixes haven't looked as green as they might, and indoors, I've been seeing large fluctuations in my reservoir. I was sure I'd get crazy root growth, but nothing I've seen has matched what I've seen in straight coco. That's what I'm gonna stick with going forward.

Still, you might get better results than I did, so give it a shot. I'd be curious to see how it goes. Maybe my problems came from something other than the mixes I used.

Those are some very good points bro...thanks! As I said in your thread...I've always been hesitant to mess with PK

im aware BIO-BOOST in NOT designed for coco.. but darn it seems to work well!

And that's all that matters Hey that's another great contribution bro....

I gotta get in on this...hell I authored the thread lol...I'm starting a water frequency side by side soon...

Thanks to all of you guys for your posts and input

hello VT

i have finally decided to concentrate on the bio-boost for flowering atleast for the mayor part of the year - only in winter i will give some heavvier amounts of PK.

i didnt even use Phosforic acid that much during flowering for ph-down, just to make sure there was as little binding of minerals as possible.. i really did almost 50/50 of nitric acid - and fosforic acid - since there is no risk for interference etc just ad first one - mix - then add the other.

one interesting thing i DID note is my astrofog (kalimsit x astroboy made by holygong) doesnt like the low nutes and heat as much as the hybrids of PURE landraces just to complicate it more :

true?:

landraces from dry condicions, pure or in hybrid form, uses less water than typical dutch varieties in same condicions

atleast this is this far my conclusion - allthough to make sure - i think i have to keep growing more landraces from dry climates.

for example - my keeper SSH x PTK by cloneman

PTK is a dry highland pakistani - im sure this has a lot to do with its needs of nutes and watering - even though its crossed with SSH.. the father genes of the PTK are dominant in most ways and definetly its hydric needs

a pleasure -

bone!

Cool deal bones I'm dealing with a leaf curl (dealt with it in DWC also) from what I suspect is LK (Liquid Karma) toxicity...when I overfert with LK it doesn't lead to lockout....but I get curling leafs....so I'll be experimenting with different approaches regarding Liquid Karma in bloom....

I have 8 clones rooting for the water frequency side by side (gonna document the progress here)....so we'll run either Trainwreck or AK-47...I have four of each rooting....one strain will be run here...the other dedicated to a PBP vs Canna Coco side by side in my show

Hopefully I'll have my computer issues resolved when the babies root

peace bro

Funny. Just earlier today I was wondering what happened to this thread, made plans of bumping it, then forgot. Thanks -VT-!

I'll post up my coco soon, this shit is rocking the fucking house

Gonna harden these ladies off...then plant into pure coco
When the plants bust new shoots and require nutrient, one will be fed/watered daily...the other "watered as needed"

Trainwreck

[clowntown]

You won't believe it, but I was JUST thinking about this thread yesterday. I was thinking, "hmm, I should bump it and make sure it doesn't die." Then also just yesterday, I asked "why aren't more people growing the 'wreck?"

And today, you answered both.

 

[-VT-]

Right on! Thanks for hanging here with us clowntown This should be interesting....they'll be flipped after just a week or two veg....

 

[Guest]

Glad to see your still contributing VT!

By watered daily, do you plan on watering it multiple times a day?

When you water "as needed" what specific details will you be looking at to determine when they should be watered? Border lined moist/bone dry? For example, if you let the container dry for an addition hour or two, will it become bone dry..

What size containers will be used?

 

[-VT-]

Edited to add: This is a handwatering run to waste water frequency side by side....NOT a drip feed vs handwatering side by side.

The little ladies are currently vegging in 1 quart containers and will pre transition and bloom in 2 gal growbags

I can document the side by side and see for myself which is most effective for my needs, and share the experiment with the community, as I am doing.

I cannot define "water as needed" for you, as it's subjective to each garden, setup, and various climactic influences. I go by instinct and feel the medium, lift the pot, or look for signs from the plants. I'm sorry to disappoint you.

I'll try my best to post updates with pictures, and document as much as I can....

I am not a scientist, just a guy wondering if I can grow some dank watering/feeding less frequently, and saving money on nutes

Hey, thanks for acknowledging my contribution....feel free to share any of your personal experience with side by sides and experiments

Coco Question

Coco Question

Hello coco-nauts,

Has anyone experimented using coco and earthworm compost mixed together? Or coco and some good soil? I grow using homemade organic nutes. I have a soil mix that I use coco in at about 25%. I have also just made an experimental soil mix using equal volumetric parts of coco, rice husk hulls, and compost/ewc. The plants seem to enjoy that mix. Oh yeah I have added dolomite to that mix at 2 tbs/gal. as well.

I have some Goldfinger clones 3 for 3 in pure coco. For starting clones I soaked the coco in water that had some coconut water mixed in it. Coconut water is very healthy for people and plants! I guess I should keep one of the clones in coco for its life...I have never used PURE coco as a medium yet...

Awesome thread!

here is the experimental mix

 

[Neptune]

Ok, here's some pis and observations.

my first time using coco, 2 gallon perfect pots with canna coco.
topdrip 1x per day at lights on, 10ml PBP 3ml Calmag.

My HKxSK has some yellow leaves and purple leaf stems.. what is this?







for comparison, checkout my SR71 PK vs the SR71 HS

PK


HS



same veg times, 17 days.


So, what is this yellowing/purpling?
Also, I did notice that canna coco could use a flush. It had a 80-100 ppm runoff... not good.
