Seb's Big Kush, Blueberry Cookies & Critical+2.0 grow

[seb88]

Welcome to my dinafem 2020 diary 

 

Firstly, massive thanks to @Dinafem-Mark for letting me try out some new strains - Much appreciated!

 

I'll be (attempting) to grow:

Big Kush

Blueberry Cookies

Critical+2.0

 

I will be growing in Coco using airpots (1l>5l>20l)

Nutrients - Canna coco full range

Feeding - hand water until final pots then automated watering (top fed with watering rings)

Lighting - Start seedlings off under 150W scope LED QB, then move onto 2x600w COB LEDs

Tent - 2.4x1.2x2.2m greenqube

 

For germination I dropped the seeds into Luke warm tap water with a little nitrozym mixed in. After 24 hours I give the seeds a push so they sink to the bottom for another 3 hours before going into root riot cubes. I keep them in a heated propogater with a thermostat set to 25degC in darkness.

 

 

As soon as the heads pop I transplant them into 1l airpots and begin feeding at 1/4 recommended strength.

 

Out of the 9 seeds dropped, 6 were successful, so we have:

3 big Kush

2 Critical+2.0

1 Blueberry Cookies

The seeds were held up at customs for a month, so they maybe weren't in the most ideal conditions during this time.

 

 

Thanks for reading, I'll update this thread weekly with progress

@seb88 you've selected 3 bangers from Dinafem 

 

You know I'll be along for the ride and watching with interest 

 

Good luck mate

 

All the best

A grow from @seb88 and a chance to get in at the beginning! I've been meaning to catch up on what you're doing with the COB's matey, hope you're well.

[seb88]

Thanks @Dinafem-Mark - can't wait to try them all, especially the blueberry cookies all the reviews I've seen rate them highly

 

@Exhale - cheers for popping in!

The COBs seem to be doing a really good job time and time again, the first is coming upto two years old now and has been faultless. Hopefully have a good few years left of happy growing before they need replacing 

[Shumroom]

Lovely start,

what happened to the 3? 

They all looked so uniform to begin with. 

 

Best of luck with the rest of the grow

[seb88]

@Shumroom of the 3 that didn't make it this far

The Critical had a 5-6mm tap root when I picked the riot cube apart but looked a bit yellow.

One blueberry cookie cracked and had 1mm of tap root showing, the other didn't crack at all (I tried dropping it back into water but no luck)

 

I'm not sure if the riot cubes were too soggy, possibly drowning the seedlings?

I had a high germ rate with this method originally but I've had a few failures more recently so maybe need to look at my technique...

 

I'm planning to flower 8 plants, and have a few plants a couple of weeks ahead of these (dropped some other seeds after these were held up at customs).

I'm hoping to put them all into flower at the same time so might try mainlining the other 2 so these can catch up.

@seb88 best of luck with your grow and a nice choice of strains.  Germination wise I can recommended  a drop of 6% Hydrogen Peroxide in a shot glass, I get 100 % germination with it and have been popping 5+ year old beans of late without issue. I know a lot a lot of experienced growers who swear by this technique as it adds oxygen to the water whilst sterilising it at the same time to prevent any nasties forming  Tapping the beans down can be fun at times as they get covered in oxygen bubbles  

 

HTH 

[seb88]

@Fragg thanks for the tip!

Is that a single drop of H2O2 in a shot glass full of water, or just H2O2?

Would you leave it in there for 24h before planting in your medium?

[Fragg]

@seb88 yes a drop or two in the water then wait til she cracks before planting, usually within 24/36 hours

[Dinafem-Mark]

@seb88 how's it going buddy?

 

All the best

Hey man

Things are going pretty well cheers, hope you are good mate

 

It's been just over a week but thought I'd leave the update until potting up which I've just done now

 

So here they are in their 1litres

 

Big Kush

 

Critical+ 2.0

 

Blueberry cookies

 

They look a bit overfed so I'm going to drop the EC a little to let them recover over the next week.

 

Roooots

 

And here they are in their new pots (before watering). You can also see a couple of other plants I've been butchering to try slow them down and let these catch up so they can all go into flower at the same time.

 

 

I'll give them a few days to settle then I'll be doing some topping and defoliation

 

Cheers

Seb

Happy roots = Happy plants 

 

They look really healthy mate 

 

Thanks as always for the diary update

 

All the best

Update time

Since the last update I've topped all 6 girls after the 4th node, giving 8 main branches per plant.

 

Plants are ordered...

Middle left - Big Kush

Middle right - Critical+2.0

Bottom left - Critical+2.0

Bottom right - Blueberry Cookies

 

Before topping

 

After topping

 

I then gave them 2 days to recover before defoliating. I removed the first true leaves and the other 6 main fan leaves from the main stem.

Here's how they look now.

 

 

My phone camera isn't particularly good and they look fairly yellow in some of these (my lights don't help either).

 

Plants are now around 6-8" tall.

They'll all be going into their final pots in the next week, then I'll give them a few days to recover/root out before flipping the lights to 12/12.

 

Only other thing to mention is that the Blueberry Cookies is a light feeder compared to the others so I'm diluting my feed a bit to prevent overfeeding.

 

Cheers

Had my first play around with LST this week. I used some plant ties and tied branches down to the airpots, didn't snap anything 

 

 

A couple of days after bending.

 

 

And they are now in their final 20litre pots.

(The other two on the left are Female seeds sexbud and RGS Kushty)

 

 

I'll do some more LST in the new pots over the next couple of days, then I think I'll be ready to flip in about a week.

 

Cheers
