FIRST DWC pot vs COCO pot. GG4 x Skittlez x Northern lights

DippingMyToesInDWC · September 2, 2020, 2:05am

Small grow. Started July 22nd.
1x Urban Guerilla (3rd homemade generation originally from Freedom Seeds)
(Gorilla Glue 4 x SkittleZ) (in DWC)

^^Day 17^^

^^Day 34 above ^^

^^Day 40^^

August
1x Home attempt of cross GG4xSkittlez with NL suffering ac wind damage, from 2 hours of artic wind straight at the plant and fungus gnats since its taking 10 days to drink. (In coco) NOW ENDED the coco plant due to the poor growth. My fault.

Cheap Amazon LED (Vander 1500w full spectrum with bloom booster switch)(200w actual)

DWC set up - single. non recirculating.
33 litre black bucket with net pot
Clay pebbles
8 litres per min air pump
10cm disc air stone.
Intense Nutrients Hydro Schedule.

Coco pot
5 litre pot before pulling out the tent (up to 50 litre pot if required)
Coco noir + perlite
Intense Nutrients Coco Schedule.

Sounds good man! Maybe a little higher PH than what I run in DWC but probably good enough. I used to try and hit 5.8.

Looking forward to seeing your progress.

Thanks mate, i am very new to DWC so any pointers would be a help,

im a little stumped how i do a res change without damaging roots? Im guessing i just move some of the existing water and net pot into a different bucket, make a fresh res get it to temp and pop it back it up? I assume i cant just drain the bucket and make refill with water while its in the same bucket?

Also correct me if im wrong i read its better to stay towards 6.0-6.2 in veg and 5.8-6.0 in flower? I had unfixable low ph issues in soil so im sensitive to PH monitoring now, made a chart to track changes daily.

Any girls of your own growing at the mo?

2K19Starter · August 4, 2020, 7:06am

If staving a little higher is a conscious decision that is probably fine - I am not sure about switching between veg and flower in DWC.

I do know that you can’t leave your roots dry while changing the res. So either just prepare another bucket and switch the entire buckets out, or store them temporarily in some water while you work on your res.

Edit: I have some girls growing atm, yes. My first coco adventure! 2 from seed and 2 clones, another first for me. I grew autoflowers in DWC before this.

When I change mine I just mix up a fresh batch. Then I set the plant into a empty bucket and just let the roots hang. Then clean the res, refill, run hoses/stones and then just put the roots back in the water. Never had any issues doing it that way. I also always let mine drift from 5.7-6.0 but usually maintain around 5.8. I always allow drift tho unless it is crazy spikes then of course you gotta get that shit under control lol. Good luck

I’m a huge fan of this one…flavor is borderline addictive. High leans to GG. Mmm.

DippingMyToesInDWC · August 4, 2020, 11:57am

I agree, i love it so much ive grown atleast one every season since i discovered it, nearly ran out of L’season smoke now :(…

But…
Shes the one in my first DWC this season

DippingMyToesInDWC · August 4, 2020, 1:05pm

As you can see, huge difference already between the grow mediums!

Also, if your wondering some cold wind got to the leaves on the potted plant, oops

cannabissequoia · August 4, 2020, 1:27pm

LOL - Same here. Won the fem Barney’s seeds from The Vault, grew only 1 outdoor last year, was amzing. I thought I still had an oz or so, went looking & couldn’t find it damn! no

So 3 in the ground this year, took cuttings of the decent 1 even thought I don’t have an indoor garden.

Same deal… gotta have that flavor forever!

When I did my first DWC I had a bucket pre-mixed then swapped, the airstone was run through the lid so it all came out at the same time and went into the new bucket.

DippingMyToesInDWC · August 4, 2020, 4:08pm

Aww thats heartbreaking man i hope it just pops up randomly to surprise you …

But atleast you get to relive the experience all over again soon

DippingMyToesInDWC · August 4, 2020, 4:25pm

Yeah my airstone is on suckys at the bottom of the bucket so not as easy of an option :(…

I think I’m gunna buy 2 cheap buckets let one warm up for a day or so
and use other to hold the existing water while i clean out the dwc bucket.

Thanks all for the input so far

Product like this makes changing water reservoirs a cinch. There’s others, doesn’t need to be this exact one.

Watch for low pH in fresh hand watered coco. It tends to initially pull calcium out of the solution which tends to drop pH. Watch for high temperatures in DWC. Add some sort of sterilizing agent to the water, it’ll make your life easier. Bleach or hydrogen peroxide or both. Sterile reservoir solves many problems with active hydroponics.

DippingMyToesInDWC · August 4, 2020, 4:49pm

Totally clueless about about DWC additives so thanks il certainly look into sterilising the water. Think i got a tool like that for my fish il just need to extend the hose

Kinda new to Coco too. (2nd grow). Started with soil before that but we never got along anymore.
I’m a bit PH obsessed at the mo so il be keeping a close eye on both.

All i know so far in regards to protecting my DWC is keep the water temp below 70f and block light from entering the bucket.
im open all ears… and eyes

vernal · August 4, 2020, 4:48pm

Good way to be. 90% of people’s problems in hydro/soilless/coco are pH related. Don’t 100% go by your measurements, read the plants as well. Calibrate that meter frquently; digital ones are often off.

If it looks claw-leafed, light lime green, yellow at the new growth, it’s low pH.

Dark green foliage, brown holes in leaves, it’s high pH.

DippingMyToesInDWC · August 4, 2020, 4:57pm

Yeah i learnt the lack of maintenance mistake the hard way
Suffered for months unknowingly had 4.8PH soil

There was no saving that. Binned.

Since then i keep a cup of calibration fluid available at times, calibrate whenever the temperature is ideal.

Thanks again for the other info

I’ve experimenting with different grow mediums recently so this thread hits close to home. I can’t wait to see how it progresses.

Just reading about PH problems gives me heart palpitations.

vernal · August 4, 2020, 5:17pm

Switch to pH drops, slightly less accurate but never totally wrong, never need calibrated.

Alkaline water is less prone to pH swings. If you have soft water, use a product called limewater; your pH will hold steadier and be more resistant to change.

ReikoX · August 4, 2020, 5:50pm

IME pH drift is the most important thing to manage in hydro systems like these.

I use that for my aquarium, never thought of using it for a res change. +1

So true, even if just to double check drops are a must!

Joboo · August 4, 2020, 8:53pm

Right and not just manage but I feel drift is absolutely necessary to unlocking a plants true full potential. A lot of people dont understand that your plant releases chemicals to raise or lower ph as they are feeding. So if your plant is hungry for x nutrient it will release y chemical to cause a ph drift to z number in order to feed correctly. If someone is constantly dumping chemical in to stay right where they want their ph they could very well be working against their plant. That’s why I just let it do its own thing as long as the numbers aren’t rising out of control of course
