coco doesnt have much of any nutes in it and u would need to use a nice rounded complete nutrient

heres my first coco grow https://www.rollitup.org/grow-journals/286741-my-first-coco-grow-legal.html

GH Base Ph Up (Dry)
See "options" to choose acid/base and size:

For plants to be able to grow best it is important that the nutrient pH be slightly acidic - the range of 5.5 to 6.5 is considered ideal for most crops.

Our nutrients are buffered as to not require major adjustments. There are some important exceptions, when poor quality water is used to mix nutrient solution, when pH unstable media is used such as many rockwool and gravel products and when plant growth rates are so high that the nutrient mix is thrown off due to rapid nutrient absorption by the crop.

Selected options:
size: Base 1.5 lb

Growing dank, priceless

Another question, I posted this elsewhere and haven't gotten a response and Jberry following your advice has brought my plants back from the dead to looking strong and health, thanks again!!! anyways, I have 3 plants all different strains, all from feminized seeds, all 6 or 7 nodes and 15-18 inches tall.
My question is how many clones can I take from each plant, it appears that each plant has about 4 good canidates, would that be too many to take at once? in addition how long should I wait after taking the clones to switch these plants to their flower cycle?

As always any help would be greatly appreciated!!!

taking four clones shouldnt be much of a problem...it will definately cause some stress tho. before plants are put to 12/12 they should have a week of no stress. IMO. not to say it cant be done tho.

JACK THE RIPPER coco coir vs soil.

First picture: soil on left and coco coir on right.
Second picture: coco coir on left and soil on right.

This last two weeks coco coir has grown larger fan leaves than her sister in soil. In side elevation coco coir appears to be larger, plan view soil appears to be larger. I think coco coir is catching up and will end up yielding more. Which looks healthier to you?

First off thanks for the advice, I will cut 4 clones per plant, wait a week then switch to flowering.

As for your plants, damn they are both looking very nice. From the top the soil seems to be ahead, from the side a dead heat... Please keep posting updates as you go through flowering as i would enjoy seeing a side by side comparison of the growing mediums.

Very nice!


I have a question for coco coir users. I just ran 100% B'cuzz coco coir and I the only issue I had was they it didn't dry out fast enough which led to some medium insects and algae. I was thinking about mixing some perlite this run. Any opinions??

If you wanted to stick to all coco you could just buy some large coco croutons, which I assume would spead drainage, I have never used perlite myself but I have read numerous posts of people adding it with little trouble

thanks raiderfan!

yeah a little perlite never hurt any i use like 2 handfuls a pot. as its so quick to dry out, that gives me the option to water every day small amounts or every other day a little more.

Some Coco Grow.

water in is 6.0ph and runoff is 5.2...should i increase ph in to have runoff somewhere closer to 5.5?

i wouldnt go any higher then 6.2, but what u are seeing is very typical of coco that is decomposing and nothing to worry about.

haha I got your finger prints, lol just kiddin, I have macro shots of my finger prints.

6.2 in or out?

6.2 going in.

but once the coco starts to break down then the ph of the run off becomes pretty irrelevant.

Why is that?

The problem is the coco. You will never get a correct reading looking at the runoff from the container of used coco . Coco gives and it takes as well.
If you are using a correctly balanced and pure line of nutrients, then up to 99% of the applied nutrient can be taken up... Once the coco is decomposing, something like 600 ppm of your drain can come from the coco or the minerals in the tapwater that are less easily absorbed by the plant. The largest part of what is not absorbed is probably Potassium. This will vary based on many factors that affect the decomposition of the coco, the daily fluctuations in tap water, the give off by the plant as well as its health, and so on.

All of this will cause PH issues in the run off, and most likely give a inaccurate reading, even though things are likely buffered out and going well in the actual root zone... Anything between 5.2 and 6.2 should be okay.

Because of these pH issues, it is ONLY recommended that a 1:1.5 extraction is used to determine coco's status.

I will find the extraction method and post it later when i get a few extra minutes.
