Watering and Feeding in Coco

I am considering to switch to Coco and Jack321 the next grow.

I red a lot of articles saying that Watering should be done every day or twice per day. Same thing about feeding 700 - 800 ppm with every watering.

Should I water and feed every day in coco with Jack321?

What are your thoughts? @Covertgrower and other coco veterans please need your opinions. Thanks :v:

I’ve already took the plunge and got 2 big ole medium quality coco coir bricks that I doubled washed + buffed nicky claims they grow far better in it , and seeing his autos I can believe it im currently working with peat moss and that retains 2x more water then coco and im already watering every other day

Thanks for your input mate! I am working with peat too. I want to try Coco with my own feeding line similar to Jacks321. I want to know if I should feed with every watering and how much.

You do not need to water and feed every day.
You can CHOOSE to water every day. It’s just not necessary.

You should water according to your environmental conditions. One thing I will never stress enough is checking your PH. Verify going in, and verify going out. Once you get everything dialed in, you’ll do fine, but in the beginning I recommend it.

If you’re getting the bricks, you can charge it with nutrients, and get the ph dialed in before a plant goes in it.

If it’s the ready to use brands, most are already buffered. Always read the label.

I feed any time the plants need water. I’m watering/feeding once a week. I have no perlite mixed in, but you can mix some in. I have one container with a lot of perlite mixed in, and it needs watering a little more often. But it still does well.
If I missed something let me know, I’m happy to help.

Thanks! I will find my sweet spot following my environmental conditions then.

I will use Coco bricks, will rinse, buffer and PHed them.

When you usually start feeding at seedling stage? At half nutrients dose and go up gradually?

I go full strength Jacks. But I would recommend half with other nutrient lines. Just to be on the safe side.

I grow with Jacks in ProMix. I always start at half strength, just to be safe, but plenty of people start at full strength. The key is to find a watering balance. It’s harder to over water in Coco and you should never let your media dry out completely because it damages the roots and any microbes you might have simulating root growth. Your girls will let you know about nute strength.

Small plants in giant pots? How do you get away with once a week watering in coco?

Also seems coco growers use smaller pots, like 3 gals, would there be a problem with using 5 or 7 gal pots with coco, which would let me have longer intervals between watering and allow for bigger roots.

Yeah, you caught me cheating. Lol.
Medium sized plants in about 4 gallon fabric pot. I also did not add any perlite to the coco. I’ll update on Friday in my journal, but I’m sure there’s still pictures of them in there from my last update.

Lol nice debate guys! Will I get into issues if I use 5 gal Plastic pots?

Yeah I want to get away from perlite entirely, hate the dust.

As long as you have excellent drainage, (ton of holes) it’ll do fine.

I got away from perlite, because I wanted soiless , but I didn’t want to have to water every day. So I’m hoping water retention will do this. So far it’s just right, in comparison to soil. Rapid growth, but same watering/feeding.

That’s why I started this thread! The idea terrified me.

As far as I can tell they’re just doing it for space. I grow in ProMix with extra perlite, so it’s similar. Mine are in 3s because of space constraints. But I put my clone in a homemade rig that’s about 8. Only 1 light feeding for her since transplant several days ago, but she’s happy and healthy.

Other reasons are, that it really doesn’t need to be a larger container. With coco, your flushing and feeding often enough that everything stays balanced, and gets enough nutrients throughout the grow. Just my thoughts.
And, if you can get the same yield in a smaller container… why not?

Yeah, to a point. You can definitely get bigger yields in smaller containers with inert media, but increasing your container size will almost always increase it regardless of what you grow in because there’s more space for more roots.

Feeding daily in coco is one of the benefits. High frequency feeding = more rapid development. You can get away with stretching out with smaller plants in larger pots. But if regular feedings are a problem there is really not much of benefit in switching to coco. Allowing it to completely dry out usually causes more problems than good. And a healthy mature plant will definitely dry out coco fast.

Thanks for your input bro! I will find a way to water/feed every two days, I am still experimenting :smile:

By the way, since it will be my first indoor grow. Which is the best time to give water? Before turning on the lights?

I found it doesn’t really matter but early in the day Is generally considered better since it can work through the day with the fresh water
