Coco Tree's

[_Underscore_]

^ and if you'd want to keep an eye on the tent remotely , I highly recommend amcrest wifi or security cameras. I have a dozen of them myself and they are worth thier wieght in gold. I put one in each room, one in front of each controller and one over all the rezs. I can check them and rotate them 180 degrees remotely and mine have built in motion sensor detection that texts me if something moves where it shouldnt and nighT vision. Mine also record video from each camera for 7 days that I can look back on. I can check to make sure enviroment and rezs are good at any given time.

Yo yo DJm, Eldaggy here. Long time no see on IG bruh, if you still got an acct send me a DM. I have been reading this thread alot because I have been trying to dial in my coco and would love to speak to you about it if I could. Im running sterile at the moment and its working pretty good, but im using Oxidate 2.0 and not bleach.
My questions had to do mostly with the roots and the dry cycles.

Are you not getting salt build up from dry cycles?

Do you sometimes have issues where some plants are drying up faster than others and if so do you water them all or just the dry ones and check on them daily?

I just flipped a room with plants in 3 gals and they are on day 10 but they do not dry out everyday or even every 2 days. I have been watering them everyday like 20%+ runoff and watching my run off, but I fear things such as pythium and underdeveloped root systems. Any advice?

Did you have any issues with bleach making your ph rise over time?

and last question

Im thinking about in my next room trying a test on sanitizing my coco prior to transplant with Oxidate 2.0, then running bennies with sanitized water for the whole round. Have you tried this method?

Hope you and the fam are still doing good homie.

Im on the same page, lost in the dosatron sauce

Holy shit....I found the page and god dam the genius of DJM strikes again..

1 Dosatron for a concentrated pre mixed solution rather than 1 Dosatron for each nutrient. I'm dumbfounded by the shear amount of help this thread has given me.

DJM you just saved me $1000's....Thankyou

What if you want to use Jacks/Calnit/ph Down?

Wont that require 3 units?

Just make a concentrated solution of all 3 in a tub with water. Look on page 36 of this thread, DJM briefly expains it.

Basically you mix your wanted ratio's with water in a concentrated solution then just use one Dosetron to get your wanted ppm.

So say normally with liquid nutes you would add 5ml per gallon of 2 separate nutes to get your desired ppm. That's 5ml per 4000ml per nutrient

5/4000 x 100 = .125%. So if you were doing a Dosatron per nutrient you'd have to get a Dosatron that could give out a .125% ratio for each nutrient.

So instead of doing a Dosatron per nutrient you get a Dosatron that can be set to 2% like DJM did.

If your total amount of nutrient to get your desired ppm is 10ml per gallon or 10ml per 4000ml

10/4000 x 100= .25%

Since you are dispensing at 2% you'd dilute that by 8 times 2%/.25%= 8

So normally you add 10ml of nutrient per 4000. 4000/8= 500ml

So if my math is right (I'm just winging it here but this is just to get a relative idea) you'd add 10ml of nutrients to 500ml of water for your Dosatron to pull out at a rate of 2% to get your desired ppm.

My math could be totally off but that's the general idea. Using dry nutes like Jacks would be the same but you'd probably have to go by weight add just fiddle around with your ph down to get the right ph.

For me using the 6/9 with a bit of Cal/mag I usually don't have to ph at all as it comes out at 5.9 or 6.0. Plus the getting the Dosatron that doesn't do the really small quantities is cheaper...heck yes

DJM- I have been having trouble getting my clones to root. Obviously you are not having any problems with that! Any tips or tricks / recommended hormones (gel vs powder) that I should try? I know this is an old thread but i could use some advice. Thanks.

Which method are you using to clone? Which media are you using? Can you give us all the details of your cloning set up

hi DJM, very grateful that you take the time to answer questions, at least thus far.

- i have a preamble and a few questions.

i bloom in two alternating 20'X20'X10' foot rms. each rm has 4- 4'X16' tables that slide apart/together. so my canopying in each rm is 16'X16" total. in each rm i use 12X 1000w de gavitas (if i recall your not a fan that i have dimmed down to 80% or 800w based on your metric of 1000w per 30'sqft and its working. so you've saved me $$$ on lighting and cooling costs.

i learned about VPD last year by accident here on icmag and immediately saw positive results. (thank you icmag). about two months ago i came across this thread and read through it a couple times, i took copious notes and now many of your protocols have been incorporated with success into my scene and i am very grateful. we've even taken to calling you "the GURU" around here and we're not the guru types.

each room has a 5 tonne ac unit for cooling but when i read about pushing air into the rms i gave it a try and was blown away by the results. i turned off the ac's. more $$$ saved

now spring is here ( i live on the sunshine coast in BC) and I've brought the ac's back online to keep my temps where i want them. also as the outside temps began to rise i couldn't keep my CO2 above 650ppm even with the burner going flat out, lights on. its just too warm out and I'm pushing too much air out of the rms. like you ill be seasonally using my ac's. still cheaper then running them all year.

my questions:

1) if we assume an outside temp of below zero, in your opinion/experience are there any limits to the size of the room and the number of lights that could be cooled by pushing air into it?

2) is there an equation you use to determine the amount of cfm's of cold air you need to push into a room to cool it? i.e. cubic ft of rm X watts X outside air temp.

3) if cost wasn't a consideration and you could have any cooling system you wanted what would it be?

many thanks

This is next level of growing, DJM you are the man now I'm going to rebuild my growbox. Plenty of usefully information and just keep on. I want to switch from soil to coco and this is my bible. Thanks for sharing your knowledge

So is everyone watering once a day straight from clone with coco in solo cups under t5s with vdp of 70%rh and 85F?

No. Fill the cup with roots by wet n dry cycles first. If it's close to bone dry the next day, Then water every day, multiple times a day or transplant.

 

[samiam]

So I would need to mix grow stones into the coco since they hold twice as much air than prelite, to water once a day?

What ratio of coco/grow stones, and pot size for starting rooted clones in for once a day feedings?

I'll start under 250 mh than 400 mh than 600 mh for veg than onto 1000 hps sealed flower room.

I've been growing small 16 plants per light hitting 2 lb a light no problem, now I only want to do 2 per light with 8-9 weeks veg so I need the plants to grow super fast.

I been using dosematic injecters with drippers for years with my soil grows so I have no problem watering multiple times a day
I'm just kinda new to coco and want to treat it like hydro to get maximum benefits out of it.

 

[samiam]

Just measure by ppm when making a stock solution. I mix 2 lbs of dry base nutes per one gallon of water to make my stock solution. Than I adjust the injecter so that it comes out at 350 ppm. Set it and forget it.

 

[samiam]

I order my nutes from custom hydroponics.

There coco specific nutes already has the si added in. So no need to buy separate silica

 

[samiam]

Is anyone using recharge I just got 5lbs of it. Gonna try it out.

 

[GrnEyes]

Whew! Lots of excellent info on here! Thank you all for the wealth of knowledge. It is very helpful. I am currently hand-watering my husband's soil grow (yes its a bitch but he doesn't like doing it so it falls on me) and was worried about all the watering needed for coco...now I am not so worried. Automatic drip system- yes please.

 

[giroldo]

Thank you For the amazing information! I love icmag.

Has anyone had issues with root aphids? Also, I too am confused about the dosatron setup/ calibration. Are there any other threads with a deep dive on the subject?

 

[Fourtay]

Hi DJM
When you grew c4, did you do anything special or specific with her? It seems like she can be a bit finicky

 

[Dtekk]

Hey DJM! What a great post, so much good info. Icmag rocks! Do you top or deleaf in your grows?

Root afids in coco. Simple fix is OG biowar full strength 24 hour brewed tea, full root drench when lights go out. Then your normal feed when lights go on. Then next night lights out do the Drench again. You will smoke all of them. I actually use tea now in every rez Change and I have no afids ever. Microbe lift at 5 mil per 50 gallons also. And 3 gallons of tea. I have no fungus gnats at all. You use this program from the beginning and you will have amazing results with no need for chemicals ever. As long as you have living bennies in your feeds no pests can live in your coco or soil. I also have killed Russets twice with full strength biowar foliars. 3 days straight after lights out. Will suffocate and kill any mite.

 

[El Pollo Diablo]

This is the most helpful thread I've ever read about coco! Thanks a lot!

 

[the gnome]

got the answer i was looking for.
btw
very nice roots!
