I'm going to attempt a coco grow after all the nute issues i fought in soil.  Everything I've read says it will need to be watered daily or every other day which wont be an issue.  What I cant find is if I water with nutes every time or is it going to be like soil where I switch between water with nutes added then the next time plain water?

Worrying about tomorrow will allow today to slip by unnoticed

Will be water with Nutes every time man from what I know. coco doesn’t hold any nutrients like soil. 

Im sure one of the Coco growers will swing by shortly to give a more detailed answer 👍🏻

Rufio has it right. Coco must be kept wet at all times so daily watering is in order. It is also VERY IMPORTANT to get 10-20% runoff every time you water to remove excess salts from the media. If your coco is prepared correctly you can't overwater a plant in coco. Your feed strength will change as your plants grow

Yep water daily at a minimum, and every water needs to contain nutrients including cal mag. The aim as monkey said is to keep it moist with minimum 15-20% run off to keep the salts from building up and creating a lockout. 

I feel like a, like a slice of butter... melting on top of a big-ol' pile of flapjacks... yeah.

In flower I feed twice daily to keep the coco moist. And only flush if needed(always flush with calmag in the water) keep an eye on your run off ec and ph levels for signs of any excessive swings.

Never put plain water through coco, it will mess up your cec - cation exchange capacity.

Always nutrient with water.👍

 

I never grow a plant, it grows me.

can I ask how you work out a 20% run off. Is it a pot size/ water amount ratio

It’s based on the amount of feed you pour into the pot. For every 5 liters you give the plant at least 1 ounce should run through the media and come out of the pot. This is an approximate number, no need to measure and calculate this. Just aim for something in that zone and you’ll be golden mate.

@monkeydo I take it you’d then pour away the excess water from your tray? Say my 4 plants were in 2 gal pots using cocoa how much water would they approximately need daily. Last grow I under watered my plant by the sounds of it. I did 2L every 2 days in 4gal pots using coca

Yes, your runoff is waste but I do a lot of outdoor container planting so my runoff gets fed to hibiscus and roses. They love it as will most outdoor plants. If you have any houseplants or container plants that like to eat heavily they will probably like the runoff too. I’ve even fed flowering trees with it and had the most beautiful spring bloom. 
The biggest use for runoff is actually guiding your grow by comparing the input and output EC. It will tell you if you are under or over feeding your plants. That’s all part of dialing in the run man. As to how much to water… hard to say because lots of factors are involved there. Temperature, humidity, age, pot size, veg or bloom, just too many factors to nail down. I water till runoff and if it’s too much or little I make an adjustment next time. After a while you will get a feel for this but a notebook goes a long way to getting everything right. Write down everything so you can see what works and what doesn’t.
