See and that's the big difference. That would absolutely wreck any beneficial microbes. using coco as medium for organics, If you bought spring water You'd be going through so much money in water you'd have to sell your kidney lol

I have been reading alot these past few days about coco and watering and there is alot of conflicting information out there. Some people are saying they water it a few times a day and then some say they wait a few days. With my coco/perlite having ewc in there would it change the whole dynamic as far as drainage? I watered to 20% run off yesterday morning with nutrients it took 4 liters per plant to achieve sufficient runoff. Some are saying to water and feed every day others are saying let the coco dry out and go by weight. My coco today still looks and feels moist but when I grab a had full and squeeze no water comes out. My fabric pots are still wet feeling on the sides. My question is how would you go about watering/feeding in my case as of right now my medium stays moist for 3 days or so?
How are these people achieving runoff and watering 1 litre two or 3 times a day is this a preferred method? God there are no definite answers out there without someone else contradicting them lol.

You're always going to get different opinions........this is mine.
I've been growing in coco for years with great success.
Coco is not soil and should not go through a wet/dry cycle or you will get salt build up.
I feed daily to run off starting around the 3rd day from sprout and twice a day in flower.
I never give plain water.........and I definitely never let the coco dry out.
If you want to learn the best way to grow in coco........may I suggest.......www.cocoforcannabis.com.
But that's just me.
Good luck.

Thanks for the info do you think the 15% of worm castings will negatively effect the coco if I water every day? Will it retain more water then it should?

I don't know........I have never used worm castings........or any other additive to the coco for that matter.
I only use GH MaxiBloom and Silica........nothing else.

I have silica, liquid karma and calmag which I was thinking of adding to today's feed of half dose Botanicare pure blend grow. Would that be an overkill?

No idea.......I have never used liquid karma and I don't use calmag..........I don't use supplements..........waste of money IMO.

I read up to 70% dry meaning 30% wet... the article is suggesting to allow some type of gas exchange (oxygen) happen in the root area by letting the Coco dry out a bit. That's what I got out of it. (when the cats away...the mice will play)

I have to disagree with your statement.
Can you provide some type of scientific proof please?

Hard to find a straight answer pertaining to watering coco, people are saying complete opposite things l some say 1 to 2 times a day others say let the coco dry for a 2 to 4 days.

Sounds right, they're both correct. Depends where you are in your grow maybe, you don't want to drown a young plant in Veg, and you don't want to dehydrate a flower in full bloom. But...it's Coco... so what do I know. lol...

Your situation is a lot different then normal recommendations for feeding.

Normally, always feed nutrients when "watering", it's called fertigation.

Once a plant has an established root zone it's impossible to overwater coco. If you run an airstone in your nutrient solution you are injecting oxygen into it which will be available to the plants during feeding. This is why multiple feeds a day, work fantastic for coco. You are constantly supplying fresh nutrients and oxygen to the roots.

I try to never let my coco get dry. Last run I had big plants relative to their small 1 gallon pots and was only able to feed them once daily. They would be bone dry in 24 hrs. When coco dries and you are feeding salt based nutrients this causes salt buildup and can lead to EC spikes in your medium. I kept my feed low and gave a lot of runoff to combat that issue. The plants turned out fantastic.
