Round 4 8k DIY Undercurrent

[ImaginaryFriend]

Nice update.

Special thanks on the VPD chart.

Source of the Chart?

But that may be redundant, as I can read the thing right off of your post. Maybe I'll just steal a copy directly off your photo. But I would like to see the complete article, etc.

But VPD describes effective hydraulic pull through transpiration, but don't we have to consider the osmotic resistance of the EC in solution? Does that document discuss feed rates, etc?

This is probably all stuff I can google. Put that on the list.

Anyway, according to the chart, my garden should be suffering with retardedly high VPD right now (35%ish)... Everything seems okay and happy, but I'd be very curious to see what might happen if I ever have the opportunity to dial in the VPD to 'recommended levels'.

Probably can't handle the truth.

It would overgrow my whole damn universe.

Which reminds me: Sometimes inefficiencies are the most efficient.

Thanks for the post-defoliation pic. Good looking structure. Going to fill out nicely.

Damn it Damn it Damn it. Rockwool starter cubes and Rapid Rooters suck.

Growth on the gods gifts and shishka berry has been almost nothing past 3-4 days. there around 8-10inches tall. While the Diablo Ogs are around 15-16 inches tall.

So a few hours ago I carefully removed bunch of the hydroton. Found some nice brown roots. Luckily no slime yet. Even though the rooters and cube were above the water they were still soaked n mushy.

Went and grabbed a sharp thin blade and started surgery. Carefully removed as much of the starters as I could. The rockwool came apart real easy got almost all of it. The rooters got around 1/2 but exposed alot the main roots and the stem. Then I reburied under hydroton. Got some Hydrosparkle on the way.

Next day or 2 i'll see if its time for new clones. The Diablo's were in a starter that has same color as a rapid rooter but is way more dense and does not retain a bunch of water.

Will definetly be busting out my rubbermaid aero cloner next run.

The Klein one was best price vs accuracy. The cheap ones were like +/-5 degrees F. So a reading of 85 could be 90.

The VPD article and chart are from Urban Gardener issue 11. Jalisco Kid talks about running higher humidty and the article expains why.

What's with the electricity on the floor? elevate that please...

 

[DonkDBZ]

I moved to ceiling cause that shit was a trip hazard. Burnt my self last run hurts like hell. Anyways being a electrician I use metal boxes and everything is grounded. So if that box was to get soaked it would trip the GFCI 1st and if for some reason that failed the breaker.

Sick!!! What is your light and plant pattern like? After seeing this, Heath's trees and Mike Roses's thread I have to try this some day. Thank you!!

thanks.

You can follow the high humidity and super controlled temps back at least as far as Krusty if you want to... I'm pretty okay with my current situation, but its not even in the ball park--hell, not even in the same city--as what those cats grew...

I have my own personal understanding of VPD that may or may not be based on science/reality. I guess I own most of the controllers to dial it in, but haven't had the right space to work those garden elements.

Hope it works well for you...

 

[DonkDBZ]

I would like to hit 65+ humidity. But only at round 50%. Thats with a kenmore 12gallon/day and 3 5 gallon buckets with some water in em. My equipment budget is gone and I pushed my limit otherwise I would buy another humidifier. Rest of my grow fund is to cover nutes and electricity.

All of the girls are making a comeback. If I would have used my aerocloner I am sure my girls would be way bigger. The diablo OG's were in jiffy root shooters and they have done the best the rockwool and rapid rooters blah.

I also added a med round airstone to each res wedsday cause my air pump seemed to be running a lil hot. With all valves full open the 8" discs in epicenter outdropped a lot. So I adjusted vavles on the med rounds so I still get full output from the micropores and the 8"ers kicked back up. Pump is running cooler and my res temps dropped .7 degree's a few hours later and have remained lower.



added some hydro-fungicide thursday


need to look up why 1 of the diablos has purple stem while the other 2 are green.

Nice one DonkDBZ!

I'm interested about those cool coil of yours. So you need to operate a waterchiller with them? Or how do they work?

I planning to do a same kind of undercurrent myself so I'm happy I found this grow.

Good Luck

 

[Neo 420]

Not using the cool tubed with this grow?

 

[DonkDBZ]

Nothing new to show. Girls are reovering from root rot battle. Finally getting new growth was thinking about starting over a fews days ago but everything is getting back on track.

Yes you need a waterchiller and pump for cool coils.
One of my favorite things about coil coils is no nutrients running through chiller.
No Tubes needed since I am running AC.

I will do a Pic update later this week

Yeah I noticed people with best success used cloners. no starters and those that did use em and had success had perfect space between starter and water level.

One of gods gifts looked like shit so pulled and replaced with a sweet tooth cross.

 

[Rip Current]

Donk - very nice looking setup. Looks like it took some time. I'll have to wrap all of my return and feed pipes next run and hopefully gain some grow efficiency.

My Q's:
Any heat issue behind the wall where you have your AC's?

How is that charcoal filter working out for you?

 

[DonkDBZ]

No heat issues with AC's anymore I have a 8" highout fan in room where ac exhaust is.

Girls still in veg so not running the filter. But I used setup that way in a sealed room before and worked just fine.

What I will tell u is those filters will not do the job for nonsealed rooms.

Shot a few pics tonight.

So concerning fungicides and roots excel. Saw this add a few days to late. Looks like roots excel is alive.



I threw some roots excel in while running hydro-fungicide. The resulting gunk



Early before the hydrofungicide roots excel left a brown film over the roots. After hydrofungicide turned to a brown sludge.

Roots looking what they should have a week ago if I would not fucked up.



some pics



For those who have read krunch's mpb thread root rot is a bitch and cost me a lot of veg time.
