Grow Mediums The Coco Home Thread -- Calling ALL Coco Growers!!!

Sweet!!!
A coco thread!!!

I am thinking of trying coco for my next grow!
Looking at the drip method but unsure as to what to do with the run-off, recirculate or discard??
If it is recirculated would that not affect the PH of the res and require constant adjustments??
Or could i fix that by using the PH Perfect range of nutes that correct the water??

Also what rate of drip emitter should be used?
Is there a standard X/gph that needs to go through the pot?

I have some books i am reading up on and a few other forums have some excellent tutorials out there.

:peace:
 
Hey lazy I use the recirc method. My pot drips right back into the res. I've never had any ph problems. I check ph once daily and rarely do I have to adjust, normally after the res change is when I have to adjust until it stabilizes.

I don't used a dripper. I made a home made drip ring with 1/4" tube and drilled 1/8" holes. The drip is set to last for 15 min. I've never measured the amount that flows through the pot but I'm guessing its probably around 1.5 gallons every feeding.

The ph will eventually stabilize itself if you allow it to have plenty of run off each time. My theory on it is that everytime it's being watered the ph is automatically being adjusted to whatever my res is set at.

My res never got dirty, it was discolored for the first couple of weeks but after that its stayed clear. Only downside to recirc is that there's really no accurate measurement of ppm, or EC. I just go by my ppm when I first make my res and leave it at that, so far so good.

Hope I helped clear some things up.
 
Thanks Truu!!!

Heading over to check your grow log and see what info i can get!
Have to start thinking about building something to raise the drainage trays above the res.
And finding the drainage trays...

Hey lazy, check out the "airpot bastardization project" thread I opened up in the DIY section, the post I put up yesterday. Maybe what you're looking for, who knows.

Anyways... I'm late for the party, but here goes what I found when using coco.

1 - Never ever ever wash your coco, if its Canna Coco Pro+ or Biobizz or whatever. That is an old to-do thing when using old-school blocks. The coco we use is actually cheaper, all thing considered. It is by no means inert, as usually described. It is treated with, among others, trichoderma mould, that is essential to kick start life. Watering the coco will automatically create microbial life.
2 - Always pre-feed coco with a light 0-6 to 0.8 EC 24h before potting. Your roots will have an orgasm when they get in there.
3 - I find that letting the coco dry considerably between waterings makes the plant much bigger, bigger roots, bigger stems, bigger buds... Have no clue why, but I've replicated results numerous times. Now, this is when the plant is established. Don´t be doing that to young baby plants. Sometimes that means 3 or even 4 days between waterings in early veg, depending on temps and RH (24ºC and 50%RH). In flowering, plants suck it all up, late flowering I water twice a day 'cos they'rew hungry and thirsty and drink it all up quickly. This is using airpots which does help dry the medium quicker.
4 - Swinging the pH... not sure yet, but I do see the logic behind NOT trying to hit the 5.8 mark obsessively. 5.6-6.2 swings is considered to be better to balance nutrient lockout vs pH meter accuracy. I'm actually feeling better results pointing to 5.7, less problem.. actually none so far. But I'm also using new beans, so...
5 - If you are blessed with springtails, you're a lucky bastard. I am a lucky bastard right now. The are hundreds os species of springtails, a minority are hazardous. You will know because your plants will die quickly, they will eat the healthy roots and not only dead matter. The vast majority however, are like viagra for roots. If you see an "infestation" of minute tiny little white creepy crawlies (less than 1mm small) that jump around when you water the plant, don't panic!

Can't remember anything else right now.

Guys.... thank you for your patience!

The discussion about a sub-forum for coco has been ongoing, and we are close to making an announcement. We have a number of coco growers among the moderation group, so you have been well represented. We hope the final decision/product will be met with as much enthusiasm as the subject has been in this thread. :peace:
 
Testerx , how do you feel about useing chems and organics together mate , ive posted a question in your organic section with not a great deal of responce if you could have a looksy that would be great its about drenching or spraying organic nutes but useing coco as a medium

as i think theres a place for the two of them :peace:

i agree. coco can be a good choice as a TLO base as well.
 
Thats coco versatility once again...:group:
