Low Pressure Aero build...it has begun!

[myke]

Honestly, most times no runoff at all. i keep my coco pretty moist once the root ball fills the small 2g pots. Every few days i will totally drench the pots tho and see lots of runoff, washing away any salt buildup.

Last run i was watering 5 times daily ala DJM , so far this bunch are taking water 3 times daily.

What is DJM. Some coco lingo?

DJM is a who, not a what

Hes a grower that has a huge thread over on icmag dedicated to growing in coco. Hes a little unconventional in a few things he does, but his room is always jam packed with primo ganja.

Its a very long read, but so much good info in there.

Coco Tree's

Hi all. My name is Don Juan Matus. Some of you may recognize me from other forums or from my old "rockwool trees" thread. Took a leave of absence after the loss of the ships captain. In that time i have converted from flock wool grows to coco. Looks like the ship didn't sink, so i thought id...

ya man, hes a smart dude and makes things work for him.

i ran my room very similar to his for my BBnc run, it worked well, best crop ive had by a large margin. just gotta have gale force winds in the room to keep the heavy air moving and be wary of bud rot near the end.

Ya great thats all i need is 4 more fans in space i dont have.Good ifo on watering.

Ya with his method, numerous fans are a must for sure.

i have 4 x 16" hurricanes and another 4 small clip fans, they were all running during that crop. RH set at 70-75% , it was very heavy when you walked in the room.

Not sure if I have an issue or it’s the plants showing a little stress from the powered up leds but all 8 have a curly look to them. Not much praying.

ph is being monitored regularly and stays within solid range.
Roots appear to look decent. Plants seem to be growing well, it’s just the appearance of the leaves, they just seem off to me for some reason.

Let me know what you think.

Puffy with dark green vains,Did water temp change?Looks like a reaction from cold water?

ohhhh man I never even thought of that.

Yes water temp did change when they moved from the cooler to the big totes. The res temps are def cooler than what the veg box.

will they adjust to the cooler temps or so I need to try and warm the water up?

Hmmm,I would see if they will adjust.Whats the temp now?monitor it for a day and see how much it changes.

temps in the res have stayed at 69-70f since it started running Sunday past, hasnt changed really. Ive been running the timer 1min on 10 off.

Temps in the veg box were 74-75f...so def a solid

I know in my rdwc they dont like a 5 deg f change when i flush mid cycle.Ive since added warm water to my grow space faucet.
The leaves show the dark green vains,this is something else i think.Mg is my first guess.

 

[myke]

The roots look awesome though,they sure like the LPA.

Ya this makes sense and something i never even considered.

The leaves look exactly as you describe, puffy and dark veins.

Ill keep an eye on them, hopefully they just adapt and its a non issue.

The roots look awesome though,they sure like the LPA.

Thanks bud, ya they really do love the aero. Prob more than i do lol

Wow, i didn't know a temp change would do that.. i have a plant right now that (cause i'm dumb) the water got to about 80 in DWC then i paniced and dropped it to about 70 really fast.. i am thinking nitrogen tox.. but i had no idea the temp chance can cause that. Do they usually adjust and pick back up?

I'm still going to cut my nutes in half tonight just in case.. but yeah big puffy leaves and twisting and DARK green...

And this happened pretty much the day after i lowered the temp..i would have never thought of that.

Temperature changes can also cause root rot (a particular one from the large family of root rots)
5 degrees (Fahrenheit) difference is not enough for that, but larger differences for sure can be harmful.
But any sudden change in temperature should be avoided.

I sometimes have 15-20F swings when I change the water and have yet to experience any side effects on healthy vegging plants. My tap water comes out 50-55F in the cooler half of the year and it takes a full day or two to warm back up to 70F.

So, do you think its another issuue causing the leaf whackiness? any ideas?

they havent improved their look but they are growing like crazy

Same here, except the opposite, when I do res changes in summer tap temps could be in the 80s, never seen any side effects to it. Takes 1-2 hours for chiller to get it back in line.

Also have to keep in mind when doing hydro/ aero I've found that ppms should generally be a tad lower than other medium mixes. I've found that to be true especially with high pressure aero, 600ppm would give me tip burn. Maybe your ppm little on the high side?
