HS1 - Think Big - 55L DWC

@@AFN-Grim

I've never done auto mate and the last time I grew they were just getting out there with the Lowryders etc, things have moved quickly though and I'm doing my research at the moment on them.

I'm really fancying Sweet Seeds' Red Poison to be honest as I'm a sucker for colours , planning to do a run on them next year at some point all going well like.

Aye all my previous was with photos and regulars though I'm running femmes at the moment for the first time for Dinafem and they are stable and doing well.

Week: 1 - Day:​

Almost four days after germination both seedlings emerged from their casing just fine. Once the seedlings are 24 hours old this is considered day 1 for my own documentation. These pictures are from yesterday.

Both seedlings are looking perfectly healthy as of yet but a little on the leggy side. They are being misted once a day with plain water set to the right environmental conditions.

Nutrient Solution:

• PH: 5.8
• EC: 0.3 ( Back-round EC)
• Temp: 19-20 C

Environment:

• Lights On: 24-25 C
• Lights OFF: 20-21 C
• RH%: 60-70%

You will love Red poison the colours are awesome and the smoke is good. Watch out for the normal coloured pheno.

Week: 2 - Day: 8​

During the week the Hydro Corn Clay pebbles growing medium was washed and then conditioned.
The pebbles were conditioned in a nutrient solution that has been listed below for 2 days prior to being used.

The Grodan rockwool cube was also washed and then conditioned for the same amount of time as the Clay Pebbles.
The rockwool cube was conditioned in a slight weaker nutrient solution than the details that are listed below.

To get everything ready each nutrient solution was drained away for both the clay pebbles and rockwool cube which were then left to sit out for a few minutes.

It was then time to place the rockwool cube on top of the clay pebbles.
This step usually doesn't need to be done, its really for my own preference as i like to be able to watch the progress.

Now to check which seedling will go on into the DWC bucket, can you guess which one was chosen?
The main tap root on this seedling is like nothing i have seen before, an 8 day old seedling with a 30cm taproot.

Safely transplanted on into the rockwool medium. Hopefully in a weeks time this baby with the giant taproot should be in the Water.

Looking forward to seeing this pan out

I've tried think different with 6 plants and they were really poor compared to xxl Dinafem plants

I'm talking 20g a plant, compared to 120g or more with Dinafem, the think different just never really seemed to take off in terms of height in 15ltr pots....

So this new hybrid will be interesting to see

Good luck with the grow and all the best

Week: 3 - Day: 17​

This week the Think Big seedling was old enough to be transplanted into the DWC pot.
The 55L pot was filled with a nutrient solution (detailed below) and let bubble for 24hours prior to transplanting.
The seedling was then placed inside a net pot along with more Hydro Corn pebbles and transplanted into Alien Hydro single pot system. Here she is settling into her new home straight after the transplant.

Temperatures were a little on the cold side for this seedling as slight purple/red tinges have occurred on the main stem.
Temperatures have been risen and the radiator thermostat has been re-calibrated in order to prevent this issue arising any further.

Another thing to note is how pale the leaves are on this autoflower.
This is due to the light feeding that it has been receiving as there were concerns about over doing it at this early stage.
In order to combat this problem the EC of the nutrient solution in the pot has been risen to an acceptable level for an auto seedling.

This is a picture from today. Notice the fresh new growth which is slightly darker.

Growth appears to be on the slow side for this young Think Big but that just means shes getting ready to explode.
The seedling is currently at a height of 11cm and a spread of 11cm and just after pushing out its third set of true leaves.

The roots were smaller than expected after seeing that massive 30cm taproot before transplanting to the rockwool.
Not to worry as the roots are healthy and even though there wasn't a big root structure it was enough to get the ball rolling.

The main tap root is almost in the water only a couple of days after being placed into the net pot and pebbles.
Growth should noticeably start to accelerate from this point on-wards with growth production almost doubling in two weeks.

Week 4 - Day: 26​

This week it was decided that the nutrient solution for this plant would be changed out every two weeks instead of every week .
The reason for this is to see if it makes any difference to the vitality and vigor of the plant and its also a great way of saving nutrients.

The HS1 LED unit was raised this week due to the growth of the autoflower and with that low stress training was begun.

So far so good and as of yet no signs of over fertilization or nutrient toxicity have occurred.
Think Bigs few fan leaves are a luscious shade of green with perfect leaf margins and excellent looking leaf blades.
The purpling of the main stems has also stopped right in its tracks as temperature were correct from last weeks update.

This plant is showing true signs of being healthy and happy bar some slight calcium deficiency rust spots on one or two of the fan leaves. The reason for this deficiency is because no Calcium and Magnesium additive has been added to the nutrient solution as of yet but not to worry it will be added before any real damage is done.

Think Big has shown sex this week which is slightly earlier than anticipated. Not long now till growth noticeably accelerates every day.

The plant has surely picked up the pace already with it being on its 6th set of true fan leaves and reaching a Height of 25cm and a Width of 20cm. Inter-nodal spacing seems to be slightly long but nothing out of the ordinary.

The roots are developing very well now with lots of feeder roots visible.
They are a pristine white colour which is a sure sign of good health.

Week: 5 - Day: 34​

This week it was time to switch out the two week old nutrient solution for a nice new fresh one.
So far there are no complaints from myself or the plant using the same solution for two weeks at a time.
It really makes sense to do this when using a 55L DWC bucket otherwise its just a waste of money at such an early stage in the plants life cycle, tossing out nutrients that aren't even taken up by the young plant yet.

Following the fresh nutrient change out a mycorrhizal inoculant was also added directly to the roots of the young plant.
To go along with that a beneficial super charged microbe tea was also brewed this week and then top fed to the autoflower.

More training has been applied to the plant this week and it will continue till the plant is spread evenly and light penetrates evenly over the canopy.

So far so good as no signs of a nutrient toxicity or over feeding have occurred.
Noting that there are no burned leaf tips and the leaf edges are perfectly straight which means the plant isn't suffering from heat stress.

All the above are good signs of a perfectly healthy plant but there were some underlying issues which have been solved and dealt with this week. The calcium deficiency rust spots have managed to find there way to almost every fan leaf bar the two newest sets. Although the plant doesn't look the best right now its a sure sign the deficiency was stopped in its tracks once new growth is healthy.

Think Big is now on its 8th set of true fan leaves and although growth has still been a little on the slow side big things are expected of this little autoflowering cannabis plant. The plant has now reached a height of 31cm and a width of 40cm.

The roots are developing very nicely at the moment which makes one ponder is this plant charging up its batteries before it really takes off or has something gone wrong. Unfortunately the roots are no longer a perfect white and as always this is due to the staining from the tea.

Currently there has not been much of a smell from this one thus far but since after adding the super tea this week a nice weedy aroma was noticed.
