Is there some way to grow completely organic with coco, or is coco best left as an ammendment when growing completely organic. As I understand that bat guano, etc. will lock up the soil. I found this by Suby:

"Here is the gist of what's fucking up in your grow, coco is a shit medium for a guano grow. It initially releases K bound up in it matrix (K+) then gets bumped for Mg+2 ans Ca+2 which then get bound in the matrix.
Canna ferts are designed for coco and you'll see they are very high in K and in Ca and Mg, these 3 elements are the trickiest elements to get into your soil throughout the grow so if I had to guess your def. was calcium and to a lesser extent magnesium. While coco buffers very well, almost too well, it takes on the ph of the fert solution too quickly that's why humic acids are in the Canna stuff to buffer the ph. Dolomite lime would have helped for ph and Ca and Mg, using calcified seaweed gets plants extra Ca but can be tricky to find. Nutrient profiles for coco are best suited to all in one ferts and usually not the 100% organic kind, a blend like PBPro with the CalMag formula added will yield very good results but not 100% organic."

Suppose a few compromises could be made for a not 100% organic grow with coco such as PBP Pro with its calcium carbonate (chalk) and other vital immediately available nutrients in balanced ratios. Not sure if just because of the calcium and magnesium carbonate that it is not considered completely organic.

I am currently doing just so... i have been in flower for 5 weeks and very happy so far.

I use a all in one flowering fert based on beeswax made my Ozigrow called monstabud. I have been supplementing with bat guano (only got it last week), seasol (kelp), molasses, liquid wormcastings, epsom salts and lil bit of fish emulsion (due to N deficiency)...

The only probs so far are what i suspect is some Mg or Iron deficiency but it could have been because my lamp was a bit too close for a while...

The top leaves around the buds have yellow streaks on them and tips are yellowing... but lower and side buds unaffected...

Anyhoos...

Good Luck

this is what i have been saying too coco is not made for use with guano or worm-castings.

what will work i'm sure is a coco specific organic liquid nute. as far as i remember some one has come up with one. i see no reason why you can't feed the coco with liquid organics.

looking good there SilverSurfer_OG

i think the same thing dude ...."why is not possible?"
i got pretty good results within use both guano and worm casting in the mix of mi coco,and plus i use to water my plants one time a week with the basic fertilizer and his stimulator.
with very good results!!!
sage clones:




my current grow ssh and lanina(shantibaba) all in coco with wormcasting and complex guano pellets:








29days on bloom

wow the Sage looks superb

that's real cool, so what exactly is the medium made of?

you are of-course right you can treat the coco like earth, it's just that i haven't seen very many people get good results doing so. it shocks me to hear you only watered those plants 1x a week. it must be more of an earth mix then a coco mix no?

you should do a thread here explaining exactly what your method is. i know lots of people want to know a way to grow organic in coco with such results. specially with only watering once a week!

peace

i think he said he only fed once a week gaius! but please do tell us your ways!!

Hey Slicker,
If you wanna go organic, try an organic nute line, make a mix of 70/30 coco/perlite and skip the soil additives. I ran this same test awhile ago and the plants were all healthy with good bud development. I used BioCanna, but you could use any commercial line as long as its a complete mix. Good luck.

This setup is the cheapest way to go for testing new products.

yes budfather ..u'r right ..i tell that i feed one time a week..but i water my plants with 300-500 ml of water every 2 days (one day yes ,one day no)

i use my own fertilizer (BIOMAGNO)made by hydrolisis of sevaral organics stuff,produced by fermentation AND REACTIONS OF BACTERIA ..and is the first one from my country and real certified for organics farming.

i open a thread in this coco section soon as possible...peace

ps: omri , skal and other fake label like these are not allowed in organic farming in my country and in the EU. they're not "registered in the list of allowed fertilizer for organic farming"

sound like this: "u can buy omri or skal ,but u cannot buy the registration number after the deep analize of the autority"

i currently grow indoors with organic ferts in a promix based medium and have some coco lying around and have thought about using it. I grew vegetables outdoors in containers last year with guano and had pretty good success i couldn't imagine that its impossible to grow cannabis with guanos. Is there anything specific i should know about growing with coco? These are the nutrients and fertilizers i have and currently use: worm castings, powdered molasses, kelp meal, dolomite lime, greensand, mexican bat guano, and indonesian bat guano. I supplement with liquid kelp, epsom salts, liquid horticulture molasses, peruvian seabird guano, meixcan bat guano, and budswell. Ive heard that with coco you should add at least 2 tablepsoons/gal of coir dolomite lime to the medium. How often should you add the epsom salts to the watering? Since coir locks out Ca+ and Mg+ would it be possible to foliar feed a mix of liquid horticulture molasses and liquid kelp? On the bottle of the molasses i have it says its a good source of calcium and magnesium and it can be used in water through the soil or as a foliar feed, but i have only used it to water through the soil.

thx dude ...for the compliments ,medium (100liters)is made from :
65 liter of coco from bricks
25 liter of perlite
10 liter of worm casting
1 kilo of ZEOLITE powdered
less than a kilo of complex GUANO with natural fosfates of potash

is a great medium for my opinion ,and i can feed more strenght than the soil i usually grow with.

i've answered about other question in post before ...check the pm...peace
