Questions about coco coir
#730876 - 05/10/14 10:29 AM (10 years, 9 months ago) |
|

Every time my coir starts to dry out and I re-water, the runoff is a very reddish "rust" color. It eventually runs clear after Ive put enough water through it, but the very next time I water its very dark again. I do flush my coir with very hot water for awhile to remove salt and then room temp RO water until it runs clear before I plant. But then once it dries and needs re-watering its rusty again.
After a few weeks of this it starts to run clear every time and Ive noticed while its still running out rusty my plants growth are stunted but once it finally starts to runoff clear all the time(or close to it) they grow fine.
Any suggestions or is this normal?

Awesome post, thanks for taking the time to answer my question.
I decided to switch to coco for two reasons - one because I'm tired of dealing with fungus gnats, and more importantly because I have a LOT of bricks leftover from my mushroom hobby Ive gotten bored with. I dont want all these bricks to just go to waste ( I literally have at least 50 of them) so I'm going to use them up but I guess I'll rinse them for days before I use them instead of just an hour. I'll also try CoGr, maybe that will help too.
Interesting that you start your seedlings/clones in such a high PPM, Ive been using less than 300 because of a PPM table I found somewhere and was worried even that was too high. My plants are as healthy looking as can be but are growing extremely slow. I'll try upping the PPM as well and switch to Canna's nutes.
Hopefully all these changes will at least make my bricks decent until I can use them all up and switch to Canna coco. Thanks again!

Its just coco/perlite in pots that I treat like soil except I have to feed every time and flush more often.

Inocuole said: I take it you're using the bricks too?
I have them laying around from mushroom substrates, so without any prior knowledge I thought it was a good idea to use it too. Luckily for me the only thing I have growing in coir is catnip.
Yeah, a few of these and a LOT of these.
I have read several places that although they're not ideal for growing they can be used fine with enough flushing. I assumed an hour of constant flushing with hot water would be plenty but apparently I was wrong.
Here's a couple white widows I have growing in this crap, been in it since they were clipped from their mom. They're doing great, I just transplanted out of dixie cups but they're a month old already and obviously they were growing very slow...once I finally got the water to run clear every time they started growing at a normal pace though. That's why from now on Im not going to plant anything in this stuff until it runs clear every time for several days in a row.

Not that much effort, I'll just put a bunch in a pillow case and run hot water through it a couple times a day in my shower until it runs clear. I plan on doing this for 4-5 days in a row, hopefully by the last day it will run clear immediately. Doubt I'll even notice it on my water bill either.

Good idea thanks. Can't wait to get rid of this crap so I can switch to some good stuff. May put some bricks on Craigslist and see what happens.

Any ideas on a good way to introduce some microbes to the medium? Are there products made especially for that?
A friend said to use "horticulture molasses", would that work?

phy - I picked up some Canna A & B, have a question for you...
I use RO H2o, and Ive been adding Cal/Mag to every feeding. I noticed Canna A contains quite a bit of Ca and Canna B contains Mg. Should I stop using the Cal/Mag altogether now or just use less?

Well a hydro shop finally opened up somewhat close to my area so I went to buy some "real" coco coir to compare it to my shitty reptile bedding coir Ive been using. Shipping kills it for me to order online or I would have tried it out sooner.
The only brand he stocks is Botanicare Cocogro loose. Has anyone tried this stuff? It says double rinsed but Im going to soak some in some hot water and see what my PPM reading is before I trust that.

Need some more advice phych if you dont mind...
I took your advice for coco nutes, I LOVE Canna...A&B are perfect, I havent had an unhealthy plant since switching.
My question is about the PK 13/14. Ive been using it for one week as soon as I start to see flowers. Is this correct or should I use it later in flowering? Ive also been using @ full strength according to the bottle...6 mL/gallon. Am i using this stuff correctly?

Have another question for phychotron or anyone else that knows the answer.
During the last couple weeks of flower I switch to RO water only to get rid of all the nutrients, then I do an RO flush the day before harvest. For the last two weeks is it ok to water with just pure RO water that has a neutral ph or do I still need to bring the ph down to around 5.9 or so like I do when feeding?
