250W Top-fed DWC aka Bubbleponic Grow Journal

And I wanted to say "I'm sure you say that to all the new grower here" Hahaha
Should have..
You made me feel so special haha ;)
 
Did I ?
Its good to have people questioning you, the day it stops you'll get too complaesant in your situation and stop evolving and exploring new paths :D

Update ! Starting to really enjoy doing those update and sharing her life with you guys !

This is day 19 of flowering. (Day 52 of grow)

Air Temp : D: 23-27°c(73-82) N: 20-24°c(68-75) Temp raised a bit due to the upgrade
Tank Temp : 20-21°c(68-70)
RH : 40-70%
pH : 5,8-6.2
Nutes : 1tsp/gal, 1/2tsp/gal, 1 1/4tsp/gal, 35L
Top-ups : 0-25% top ups
Lights : Youhou, made the switch to 400W and everything is working great !!

So lots has happened since the last update 3 days ago.
As I mentioned previously I cleared her canopy and was about to give her the first session of a 2 days haircut. I am now done with both session and have rearranged everything nicely.

Between the 2 haircuts I went and met up with a good friend, Lucy. We had a great journey and some excellent talks, when it came to my girls we brainstormed and decided to improve the box slightly.
I spent a good portion of a night working on them, it was fantastic ! I took out my wooden anchor plank and added cable ties as anchor points as twisty ties were not strong enough anymore. Unfortunately I did not have stronger twisty so I stripped some old cable and used the inner wires, works perfectly and makes everything look very colourful. My plant were getting too close to the light so I had to make a plan, I've tied them all down and managed to gain around 5cm (1.9in) and reorganised all the colas and the canopy for maximum light and light penetration. And some general improvement and tidiness int the box as well.

As I moved to 400W I noticed the radiant heat is intense, had to check everywhere for hotspot and maximise air movement, after a long trial and error process I managed to find the right positions.
If there is one thing I learned during this grow is that however powerful your extractor is you might still have some issue with heat (in small grow area). But all this can be fixed by a good air movement, placing fans and extractor strategically saved me up to 2-3°C (5-7°F).

Here they are now, there is 3 picture, 1st is before, 2nd is after 1st haircut and third is them now.

This is day 28 of flowering. (Day 61 of grow), they turned 2 months today !

Air Temp : D: 25-29°c(77-84) N: 20-24°c(68-75)
Tank Temp : 21-22°c(68-72)
RH : 40-70%
pH : 5,8-6.2
Nutes : 1tsp/gal, 1/2tsp/gal, 1 1/4tsp/gal, 35L
Top-ups : 0-25% top ups

They recovered very nicely from the defoliation and got very thick again quickly, I did some clean up and small defoliation between this update and the last.
As you might notice the second plant on the right is nearly gone, I had to chop him down, yes you read it right its a him, well a her as well but way more him than her, so as I can't remove him from the system as the roots are way too entangled I will have to keep watching him a cut any pollen sac he produces... Not ideal but can't think of another solution.

On the other hand she is giving me trouble ! She simply doesn't want to stop growing its ridiculous, she now stands at 115cm (45in) and would be standing at 125cm(49in) if it wasn't for all the bending...
Which by the way started splitting the stem... tapped it all together and lessened the tension. The tension pulling down on the plant also made the net pot go through the lid, I can't fix it as the plant is too tall and if I lift it the colas are going to start touching the cool tube... Its a mission...I even had to unscrew the shelf where my lamp is attached and extractor and else to try and lift it up to gain more space for the plant... once again, a mission !!

But other than that they are doing good, bud site are getting very hairy ! Beautiful to see!

Otherwise,you can see the tip of my leaves are always slightly curled and brown, I know it can be a sign of nutrient burn, but they have had that for now over a month and I've been decreasing cute strength and even only give them plain water refill during a week but never goes away.. Any thoughts on that ?

Cheers.

Hi Ingwe, great first grow. I applaud you.
I'm new to this game too. Found hydro beyond me and switched to soil. The main problem being with pythium and generally around week 5 into flower. I understand hydro is supposed to produced bigger yields??? I was wondering if you knew the equivalent to HYDROGUARD here in the UK. Having tried loads of growshops without any joy.

One thing I would suggest is to proceed with seeds next time. You'll know what you are growing.

Merry Christmas

Did a quick defoliation yesterday, here she is before and after. She needed it but mostly the stress of the defoliation slows down her growth which is what I am looking for.

Thanks Silverback, much appreciated !
Yeah who knows maybe a first grow in hydro might not have been the best option but well we'll see how she does... You are scaring me with pythium comming at week 5... I'm nearly there...
And yes hydro does tend to promote faster growth and bigger yields.
As for Hydroguard... I have no clue, I don't think there is any equivalent anywhere ... I ordered mine from the US.
Yes I was supposed to receive my seeds before the grow but unfortunately got lost in the mail... So had to use random seeds..

Green75 , I did not think of that, although already did it by mistake on a few branches as they snapped when I was bending them, taped them up and now I see she healed very well, might try to do it on purpose next time. Thanks

This is day 35 of flowering and day 69 of grow.

Air Temp : D: 25-29°c(77-84) N: 20-24°c(68-75)
Tank Temp : 18-21°c(64-70)
RH : 50-70% Starting to have high humidity... not good, busy trying to find a way to fix that.
pH : 5,8-6.1
Nutes : 1tsp/gal M, 0 tsp/gal G, 1 1/4tsp/gal F, 30L Stopped giving her grow today and will see how she reacts from there.
Top-ups : 0-25% top ups

Those plant are taking so much of my time haha , its great !
Everyday I need to tie them down as they keep getting taller and taller , you can see on the picture how much I had to bend those stems.. But they are doing great and don't mind it too much. If it wasn't for the bending and tying down they would stand by now at approximately 135-140cm(53-55in) instead of 117cm(46in) now.

I've just had my 1st encounter with root rot ! But I caught it fairly early (roots were getting really dark), and managed to heal the roots. To do so I added everyday 5L (1.3gal) of ice cold water, wether ph'ed or with note top up, and HYDROGUARD, 115% strength. Kept my tank at a comfortable 18c°(64) for a while. Roots were back to normal in 2 days.

Otherwise as Green75 suggested I started intentional super cropping, or at least some version of it. I will add picture of that once it is healed and I remove the bandage.
I basically bent some of the branches and tapped them up and some occasionally snapped by themselves as I was pulling them down with twisty ties, I have around 9-10 places with bandages... but once again she didn't mind it at all, she just keep growing and growing.

The burnt tips that I mentioned previously still hasn't disappeared even after a full week of ph'ed water top ups. Will see if with supercropping and starting to produce buds she might eat and drink more.

Shame man ... It already happened a few times here but I keep bending and pulling down, working for now.
How did your bud look in the end? Did it affect it a lot ?
 
Oh cool ! Thats an interesting bud shape !
For now I managed to keep them below the light but some colas are too close and some of the leaves are slowly fading to yellow , but its cool and I don't really have any other choice...
Did you supercrop those colas ? Or is it a "natural" bend ?
