I really got some information from here before starting my first coco grow. I thought I was prepared. I would have never thought of root rot in coco i thought it was impossible. I am really disapointed in gold label coco. My friend said it was a good product.

Not that it's any consolation, After much research, I did exactly the same on my first coco grow. Killed the roots with a single watering when I transplanted from 1 gal to 3 gal plastic pots. They never used any of the water, just sat there looking sicker each day till I transplanted to fabric pots with fresh coco with a higher perlite content. No big deal, they all recovered after weeks of only watering when the pots were light. Switched them over to 12 hour light last week. still only going to water every other day for now.

Now to never make that mistake again....

I thought with that much perlite i can water everyday? What EC are you feeding?

I figure I could water every day at this point too. Just think they are doing good at every-other-day for now. I water at EC 1.1 no tip burn, leaves are not as big and dark green as I have seen in past grows. Also my first grow with an EC meter.

You have to do what works for ya... if the environment is not optimal (and I dont mean bad or not good just not for maximum growth) then you need to account for that. The biggest impact is root and leaf temps. If you optimize them you also need to make sure the coco is rinsed well and not compact with enough perlite. Light is enough to push photosynthesis and the EC is in a good place. Etc etc etc.

As long as you keep an eye on runoff watering less shouldn't be an issue if they are not drying out to much and not sucking the water up like mad. You can absolutely keep coco between 30-60% and have good results. But if everything else is optimized then high fertigation will really help keep a stable media and give phenomenal growth rates very close to hydro rather than closer to soil.

There is definitely more ways to skim a cat than the one I posted.

Thanks, I checked them tonight after watering last night. The top was dry compared to last week at 1 day. But not light brown dry like day 2. I watered them 2 gal for 7 plants in 2 and 3 gal soft pots. Minimal runoff.

As for light levels I have a meter and show 65,000 LUX at the tallest tops. LEDs are set to 80% at 18". Safe to turn them up more?

Put up a pic of your plant in its pot so the medium can be seen. 👍

I don’t think root rot is impossible. You may not be able to over water it but you can still get root rot. Especially if the valve malfunctions.

Are these in flower? 60,000 lux is getting up there for flower maybe 65k in flower but if your in veg that's probably to much light.

I switched to 12 hours 2 weeks ago. Was running < 50,000 lux during veg. Upped the brightness as the plants got healthier and trying to get the grow room temp up. I have a guide that suggests 80,000 lux is the max.

I will raise the lights to get the peak below 60,000.

If theybarw good leave em... 80,000 is probably with co2. 65-70k I'd say likely about max without.

70k but for what room size?
Click to expand...
Room size doesn't matter... its 70k across the canopy at canopy height. Of course it will vary but that's about the peak amount for most strains... I have had mine up to 85-90k with high co2 but even then they are pretty stressed and I would wanna leave it there.

Aqua Man said:
That's really pushing it imo... definitely not all strains will accept it and you will all but certainly need co2 at that level.

Well I got like 10qm with 1500W Samsung stripes.
300000 lumens. How can i find out if it is overkill for me? They doing great. Watering every two days now until they have proper roots in the new pots.
