has dr vondank done that before? Would you use coco or soil nutes? mate if you can get coco nutes i'd seriously go for a mix of coco and perlite, if you can't get coco nutes i would say using 50% coco would be a bad thing. like i said though this is all speculation, i've never mixed coco and soil. Thinking about it, maybe you'd be fine though weed is pretty tough i just can't see it being ideal. hopefully someone else can chip in though.

you should check out the international cannagraphic forum, i think they have quite a big coco section.

i dont have any coco nutes,i was trying to fina the best ratio for a soil perlite coco mix couse my soil is a little strong,i live in a undeveloped part of europe so i dont have excess to everything i need i have to inovate,i wanted to check first with some expirienced growers so as to avoid a mess,at the store they told me its ok than i found on a site that u shouldnt use more that 30% coco in a mix with soil,and now the doc told me to go with this mix they a stated in the thread,so im a little confused,i think im gonna try both

hi panta i think you would be best to pick one or the other,other wise you may have trouble with the nutes as well coco nutes or soil nutes,as well as if the plants dont do well or start dying or whatevere you are going have a hard time finding out what the problem may be.also coco and soil take up nutes at a different ph range which may not suit one or the other.i think you will be adding more work and problems for yourself.

I have and some in cocoa and some in FF ocean forest. I have been using the same ph levels (6.5-7) on all of them and the ones in cocoa are definitely lighter in color, someone suggested a possible zinc deficiency to another poster. After reading this thread it appears my ph is way too high, so manana I am going to flush all the cocoas with lower ph and see what happens. Great thread.

does ph rise when the coco dries out. im using coco in a ebb n flow system and the ph rises over to 7.5 everyday. im feeding 4 times a day 30 minute intervals 21 hour day.

also looks like i have a nitro prob. bottom leaves are turning yellow. moving upward. they r in early veg. from reading the thread only thing makes sense is that high k in coco is locking out the N. and possibly that im using earthjuice in a resv. and some of the nutes settle to the bottom. i just tried adding another water pump to stir it up a lil. well see if that helps. what do you think?

hi widowman there was a graph on here the other day that shown the difference in the uptake of nutes from soil and coco and at what levels of ph it happen at.but i would say your ph may be out just abit to uptake of the nitro.the nutes i use are ph buffered so just add to water and they are ph at 6.0

I may be able to shed some light here. I use coco but in pots. And yes, the ph does rise. I typically water with 5.8-6.0 ph and get runoff in the neighborhood of 6.3. Some strains like more acid and I have to give 5.6 to get runoff of 6.3.

everyones grow room is different.but i know people that put clay balls in the 1st 2 inches on the bottom of the pot to help stop root rot and mix perlite to help with drainage

Is coco coir the same thing as cacao mulch?
If so, please keep it away from your pets... most would have an aversion to it but a small percentage are attracted to it, and of those the majority will die or suffer sever damage if ingested as it contains theobromine.
As I said most animals would not eat it if you tried to force them... but you get dogs that eat shoes.

bump

any ideas why people add anything (such as perlite) to coir?
seems coir is pretty good on its own (if you get a N booster)

yea lots of people add perlite in order to increase the oxygen supply to the roots. The resulting air pockets allow the roots to breathe and more oxygen = bigger buds. Also, it causes the medium to dry out quicker so you can feed more often and the more you feed fresh nutrients, the bigger the buds get as well. So perlite more or less makes coco even more like hydro and less like soil. Personally I keep it 100% coco because I get more than satisfactory results and don't have to water every day.

Hey all,

Thanks in advance to any replies.

I have Mel Thomas' book "cannabis cultivation," and he recommends coco coir.

Right now, I have eight plants in vermiculite using a passive (tray) hydro system. Unfortunately, from what I've read, vermiculite eventually begins to rot. So, I am transplanting into either perlite or coco coir. What do you guys think I should do?

Again, I am using a passive hydro system. Basically, the pots sit in a tray, which is a makeshift res, and I fill it every day, adding nutes to the tray every other day. Because of this, the medium i use has to be able to absorb water well. Thanks.
