Imho with coco unless using large pots to avoid watering often with no perlite its just to much to hand water. Imho this method will give the best results bit that does not mean that other methods don't give good results.

Temperature of the rootzone is going to play a very big role. 70-80f i would say are acceptable for high growth rates with the higher end being more beneficial. This also has an affect on the amount of water taken up. There are several things that go hand in hand with making coco growth as good as possible and this is only one aspect.
80F in the root zone/water temperature? I think that is a bit high.

You can find good articles about the root zone temperature and it should not fluctuate too much. The roots can't adjust to the temperature like the leafs can. If im wrong im sorry.
With an automated watering system you can keep the medium/roots at a perfect temperature and this will increase the root mass and also the nutrient uptake.

In hydro is where it becomes an issue. In coco, soil 75-80f is absolutely perfect also as shown in your chart, my personal experience and some studies. Your absolutely right temps should stay stable and I always suggest watering as close to the rootzone temp as possible to prevent shock. You dont wanna water with high temo water into a cold rootzone thats not what I'm saying. I'm saying we should keep rootzone temps in that range for optimal growth. Not much above 80f things start to go downhill fast but up until then they improve.

Wow thanks for the informations. I'll write this in my grow book 👍👍

How do plants get on when it rains, and the rain is cold? They're going to have to have, whether they like it or not. lol
Same as indoor... they get along with a little shock. Its only ideal to water at the same temps but not gonna kill em if ya don't. My thought is of we are gonna play GOD let's play it to the nest of our abilities.

Like warmer root temps we don't see outdoors but you can absolutely see an improvement when they are increased up to a certain point so why not if we can.

Same goes for increased co2... many things are not needed but are beneficial

I have a water heater. 😁

Mine goes in between 16-19 deg... runoff comes out bout 22deg..ihave been very hesitant to give my seedlings now young veg plants daily waterings.was watering every 3 days for a fortnight then 2 now feeding daily..yeah pots are heavy .it blows you out specially if you have been an outdoor grower all your life..i have had to build my confidence up and trust other guys with there knowledge and listen to what they are saying and willing to learn..and im a stubborn bastard..i must b going soft with old age ha...

Aqua what do u use to avoid pest or flys with the coco coir at 100% of humidity all time?
I dont run 100% humidity. I have a sealed room so I'm mindful of when I go in but I used to keep some yellow stickies around to spot any issues. Always mindful of the media I use because if I dont introduce them then no issues. Personally I haven't had to deal with bugs so my IPM is for lack of a better term piss poor tbh but I haven't found a need to incorporate it yet. Healthy plants, sterile pest free media, good hygiene practices get me by because I my room very well sealed.

Placing an inch layer of Gnat Nix on top of the coco works great to prevent gnats. You can also use a layer of perlite, or sand to accomplish the same thing. Basically you’re preventing the adult gnats from getting back into your coco to lay eggs. I use the yellow sticky traps to monitor the level of infestation.

I'm in my first grow ever. 70-30% coco perlite mix in 2.9gal fabric pot. Watering twice a day, using 2lt of water everyday. I felt like wasting/using a lot of nutrients, but a few times I had not watered in the morning and next time I had to use almost 2lt of water to get run-off. So I thought I would be using the same amount anyway. It just can make you feel overwhelmed sometimes, watering twice a day, especially with multiple plants. It was recommended watering at least three times a day for my pot size but it's too much for me with hand. Don't you need to get run-off in soil also? So when you water soil every 3-4 days, don't you use a lot of water? I thought maybe the amount of nutrients wouldn't be that different? Like I said this is my first grow ever and it's in coco so I have zero experience with soil. I'm happy with it mostly, it's 53 days from sprout.

I'm on my 2nd grow, first time with coco. I have 4 plants in a 3x3 tray, 3 gallon fabric pots. For maximum yield, is it best to have this many bud sites?

I really don't know. I've done LST and opened up the branches to make them get even light. Even today I pulled some branches down and tied them to make the canopy more evenish, but it's opening the canopy 'cause the branches don't bend anymore. It's SLH autoflower.

I would like to set up an automatic watering system in the future, for now I can only do hand watering, if it was not such a hassle I would definetely water more than 3.

When you talk about root zone temperature you mean the area at the bottom of the cabin or the water in the rootzone?

I've been having very low run-off EC for a while, it's been almost a month maybe. For example last watering I used a mix 1548ec and the run-off was 279ec. I have another plant coming from behind and the same thing started to happen with her too, the run-off ec level gradually decreasing. It was up to +300 points for both, like it says on cocoforcannabis. It says in there it's an anomaly and should self correct but not happening. Do you have an idea what's causing it and should I worry? Thank you.

many times when i see the runoff ec start to be much lower than the input ec it is because of excess nute buildup in the medium. If i feed a light dose it starts to pull out the salts and quickly shows the actual high medium ec.

I put 1.5ec in and only 1.2 came out. Thought they were hungry. But then they looked overfed so i ran a .7 mix through and 1.7 ec came out.

Salts attract salts.

I'd say its eating up the nutes and not watering frequently enough would be my guess. My runoff is consistently lower but only by about 50ppm

So I should feed lower EC to get higher run-off ec? That's weird, I would have never guessed. I read that if the run-off ec gets higher that means that you need to water more often, but my EC is very low so I wouldn't think there would be salt build up. The tips of the leaves shows burning so I think you might be right. I will try a lower EC next time. Right now I'm feeding with a mix around 1500-1600ec. It's on day 56 from sprout, slh autoflower. What ec should I feed? Thank you.

Thats the exact same thing that happened on my first grow.one plant was waay under at 250 ppm when i was feeding around 8-900 ..so gave it more..problems didnt start till flower room and i knew they were getting too much as the plant had tip burn so i flushed and ive been fighting it right through flowering.i was running heaps of runoff so how does it actually build up if are youre running heaps through and was flushing till it was 5-600..this is pretty much the only problem ive had and because of that im feeding 250 ppms once daily and im at 3 weeks and im going to increase it 50 ppms every three days till 6 weeks are up and will b at 650 ppm time i put them in flower room..
