LED Growers Forum

Welcome to my latest grow, 3 plants in total, just as a test grow before I grow some Dutch Passion Auto strains, and then perhaps some Southern Star regulars in the New Year.

There's a bag of buds on the table over there, knock one up, and come have a look at my set up....

I'm growing in a 1.4m x 1.4m tent with 6" air exhaust and 4" intake, running 24/7... no carbon filters yet.
I feed them the House and Garden Coco 2 part nutrients with the full range of H&G additives, and they have 1x Helios 6 and 2x Helios 2's, 28" above the plants on a 18/6 schedule.



The plants:-
2 x Critical Jack Auto - This strain by Dinafem has genetics from all sorts... Critical Mass, Jack Herer, Shiva Shunk, Northern Lights #5, O Haze and Lowryder. It is a high CDB strain, and takes 70 days from seedling to harvest. It reaches up to 2 or 3 feet high under appropriate conditions, with lots of light, warm temperature, and an aired substrate. But it doesn´t grow much if the conditions are not perfect, yet quality is always good. The quality of the final product is what makes the difference from less enhanced strains. I should look forward to hard tight buds, strong odours, completely covered with resin, and intense sweet flavour, with hints of lemon and frankincense.

1 x Chronic Ryder Auto - This is another strain from the Joint Doctor... a cross of Lowryder #2 and Chronic, taking 65 days to harvest. It can pack on a lot of weight due to its dense, prolific budding, producing very large, resinous nuggets with 12-14% THC.

I planted the seeds direct in 100% Coco each in a 22L airpot, covered them with clingfilm, and 3 days later they germinated and popped their little heads through. I gave them a 0.6EC feed and the next day 0.7.

They stayed on 0.7EC till day 6, and on day 7, I upped the EC to 0.8, which they stayed on until day 9. Today on day 10, I have increased the EC to 0.9.

As well as the H&G Coco nutes. they are getting the following H&G additives....

Drip Clean 0.1ml/L
Roots Excelurator 0.2ml/L
Amino Treatment 0.1ml/L
Nitrogen 27% Boost 0.1ml/L

....plus they get a little CalMag (I use 0.1ml/L as an additional buffer in my 0.2EC tap water), and I use Silicon as a pH up. The plants also receive silicon from the Amino Extract, and I understand the Coco is enhanced with CalMag as well as being buffered.

I hand water them 0.5L pH 5.8, 3-4 times a day to get a semi-hydroponic effect, and they seem to be lapping it up...





The plants are doing very well in Coco, absolutely exploding with growth, appearing larger each time I go to water them
They are between 8 and 10cm high and 12-15cm across.




sorry about the lighting, this one's with the LEDs turned off


They quite nice and green, all the way to the cotyledons.

Temps have been better managed going between 18 and 28C with RH between 50 and 70%.

I plan to up the EC by 0.1 every 5-7 days, reaching a maximum of 1.5 - 1.8.

If you have any hints and tips from here, it would be much appreciated, thanks for dropping by!

OMG these girls are on steroids, just under 2 weeks in, and they are looking lovely...

Chronic Ryder

Critical Jack 1

Critical Jack 2


They are thristy girls, and chomping down nutes at 1.0EC 3-4 times a day, under 10 Helios clusters at 28 inches. Temps have been a bitch today, with ambient at 42 at one point for fux sake.

Here is a group shot to finish....

From the top clockwise..... CJ2, CJ1, CR

Thanks for taking a look, more soon.

looking nice bro

Day 16 progress report.

I'm still amazed at the progress. They are thirsty girls with CJ2 being the biggest, maybe because she's been under the Helios 6, while the other 2 (of which Critical Jack 1 is the next biggest) are under a Helios Pro 2 each.I have placed all the lights close together to allow overlap of light coverage.
I had them on 1.0EC from day 13, but the run off was 0.4EC so I have increased the EC to 1.1 from this afternoon. I will probably keep it there until day 21. I think the Critical Jacks are doing really well, but the Chronic Ryder is just showing a few small brown patches..... one of the pitfalls of growing with 2 different plants with different needs.

I have been adding various House and Garden additives:

Drip Clean always at 0.1ml/L
Roots Excelurator gradually increased upto 0.3ml/L
Amino Treatment gradually increased to 0.2ml/L
Nitrogen gradually increased to 0.2ml/L
I introduced Multizyme today at 0.5ml/L

In reality the EC of my water to start was 0.2, I added CalMag as extra buffer to 0.3EC, then added nutes to 0.8EC. The additives bring it up to EC1.1. pH 5.8. The Coco is prebuffered with CalMag and has added Trichoderma.

Thanks for having a look

looking stonking tee mate............... the previous learning is comming out fine mate................... dont forget they are fems so keep eyes peeled around the begging of day 21 to 35 for any nanas etc................... you dont know the strain so it is pos tee..................... better to look and find than find to late !!..........

but they are looking right on the mark teetee.........................nice work man...................... the JH will be a killer sativa...........!!........ AB

cheers AB Bro,

how ya been man...... bet you've been caning the Desfrans!

nice and green friend.

Thanks Belfiore mate... what are you growing at the moment?

Day 21 update

Greetings all, my ladies are 3 weeks old today, and doing nicely. Good thick main stems, and plenty of leafy branches.


The Critical Jack 2 has always been the pick of the bunch (it was under the Helios 6 for the 1st 2 weeks) and the Chronic Ryder the shortest, so I swapped their positions, putting the CR under the Helios 6 to give it a bit of a boost. The LEDs are 20" above the plants.


They are hungry and thirsty, taking feeds 3 times a day by hand, at EC1.2 and pH 5.8. Run off is EC 0.7, so I might increase the EC again in a couple of days.

Additives this week:

Drip Clean 0.1 ml/L
Roots Excellurator 0.3 ml/L
Amino Extract 0.3 ml/L
Nitrogen 0.3 ml/L
Multizyme 0.75 ml/L

I finally got round to setting up the Harvest Master control unit, which I used for my previous DWC grow in a sealed environment running CO2...... well this is a tent, and although CO2 might help with high temps.... there is too much extraction, and I would be forever pumping CO2 in. I'm just using it as a simple environment controller.

The Harvest Master has worked wonders keeping the temps and RH within reasonable limits, now I get a max of 28 and a min of 22, and RH is between 50 and 70%. The lights are now on 20/4.... another bonus of the Harvest Master and it's excellent climate control.

l ordered the Blumat watering system, so hopefully I'll be able to install it before they get too big and greedy.

Here they are:






Thanks for checking in!

very nice teetee bro, green and lush.
very nice for 21 days, well done.
