Are those 4 inch netpots? It seems to take my seedlings forever to show roots with 6 inch pots

GrumpAzz!!
Those net pots are 5.5 inches

GrumpAzz!!

Same size net posts in my current culture setup. 5 1/2 "

Edit: want to mention that there is no difference in the depth between the 5.5" net pots and their 8" net pots

Good morning/afternoon/evening and night folks

Just finished cleaning and transfering the plants into the system last night. Some plants made really good root development in those kratky buckets.

Before i placed them into the system, i flushed those net pots with some 1% peroxide solution and gave them some top watering with new solution of 250ppm. Nutes ratios (calmag.green, brown,pink)1:1:1:1
Water temps around 20C, ph~6.0

Today they looking less happy, i think maybe i shouldn't top feed them. To me they look like overwatered. Rockwool might absorbed a lot of water. Now i have some fans blowing on them and warm temps, to see what happens.
Also noticed some small rusty spots on some leafs.

All opinions are appreciated sirs

Kind regards

Oh yeah, i was reading a lot about kelp for foliar feeding. What you guys think about this one. Anyone using anything similar?

Try lowering the ph to 5.8, i aim to the lower part ofthe range in veg. Range being 5.5 to 6.5 (i tend to stay between 5.8 and 6.2). There's plenty of ppms there if their hungry. No need to hand water when roots are in the water.

 

[Bushman]

Smoke, thank you so much!!
Nice charts, corrected my PH already

Darn'it, it's like 3rd time you telling me don't hand water when roots hit the water... Im prone to learning the hard way, sorry about that.

Thank you for your patience, i highly appreciate it

Charts, setpoints, data, lookup​

I starting to think that rinsing those net pots with 1% peroxide wasn't a good idea at all. I might've burned the plants..
Nothing explains such reaction to me..
Yesterday they were fine..
what an idiot lol

 

[smoke]

Its called mild stress training, but yea they do look pissed

Probably shouldn't do that again, they'll be fine, i think

I use soluble kelp too

I'll foliar to quickly fix deficiencies as well

one way to learn.

I wouldn't think 1% Would do that

I would say heat or light stress, but lights are on 25% and temps are mild.

Very interesting, what did i missed.. Don't remember spraying them with glyphosate also

 

[steamroller]

How's the RH?
Looks to be drying out fast?

Sorry I’ve been mia a couple days.

Can you get your temps up?



With led lights low your leaf offset is not much so I put in 1

Your VPD is far too low. That bottom number should be much closer to 1. Like this




Also yes 1% straight is tough on new roots. That is 10000 ppm and will kill everything including root cells. Hopefully it was a quick dip

Straight up 1% with no water, I can see that.

 

[Bushman]

Moe hey!!!

As i understand, 20 celcius is not optimum condition for VPD? Working on those temps as much as I can already.

Just for the record, what about peroxide. What concentration would be appropriate for rinsing those little plants? I know you told me to get some ppm strips, but im afraid its not possible atm.
And yes, that was a quick dip..

Since you have your lights turned down, perhaps you can back them away and turn them up to get the temps up? If you are actively adding humidity, bringing that down a touch would help as well.

1% H202 is 10,000 PPM
.1% = 1,000
.01% would be 100

I would want to dilute 1% 100:1 to get down to the 100PPM range before swishing things about. Then rinse with clean water when done so the h202 is not just sitting there in your media as there is no active washing of that media in your system.

So use something like 1mL to 1L water.

If you doubt what I am saying, clean your kitchen with straight 1% and no gloves. By the time you get done, your hands will be white(er).

I know little but in my medical job, peroxide will "whiten" skin where exposure is prolonged, Dr. Dingledorf at your service, carry on.

Greetings Bud Builder!!!

No doubts at all. I use peroxide all the time to treat wounds and scratches. I'm a field worker.

Ohhh maaan, that means that peroxide was absorbed into Rockwool cubes, slowly damaging the plant... Rinsing it with some plain water would help i guess.
But it is what it is

Thanks for the insights

How are your plants, @Bushman? Did they make it?
