Sativa HPA Aeroponic Grow Experiment 2021

[leblanca]

Hello again,

This will be my 2nd run with this Aeroponic system, it has worked well enough to give me a descent harvest, the start was rough but i did learn a lot.

There has been some improvement made to the system,

• The totes have bolted lid instead for closing them without removing the tote instead of duct tape.
• The humidifier has its own pipe and waterproof fan to bring more air in the tent and cause no water leak in the tent
• The light have been completely changed from 2x 1000W MH/HPSS to 32X 50W LED

I started the seeds the 3 January 2021

• Jack herer
• Blue dream
• Green crack
• Raspberry cough
• Wedding cake

Started them in rapid rooter plug sitting on a wick material to keep them moist for the first week in a dome.
The root developed well but were now going in the wick material so they ewre gone break when i move them so i had to chance their groing environment.

I made a LPA aero bucket to allow my rapid rooter plug to grow long roots for their future HPA aeroponic room.
It has worked very well and the plants all grew roots.

Today i moved them in their new home, hopefully they all survive
Adjusted the PH to 5.5 as it always drift upwards after a day, my TDS is at 210.
I use 10ml/gal of 3% peroxide.
Its very dry here so im trying to keep the humidity at 50% but since its not a closed system lots is lost.

The system all ready to go, i have set my timer to 3 sec on and 3 min off.

Superb work. Maybe you could hold a clinic of sorts. kidding, your grow is on the next level.

Following this thread. I'm one stage behind you in my first aeroponics grow (seeds just popped) so this will be a good learning experience. Your previous grow journal was very informative, thank you!

Everything is still alive after a few days in the aeroponic chamber, some are flourishing while some other are still recovering from the transfer.

Today i notice that every plants were growing roots, some faster than other which i think is caused by a difficult transplant of the roots through the net pots as some roots gets damage or dry up near the rapid rooter as less water droples get there but overall it looks promising.

This green crack is doing really well

Yesterday i had to do the water change, having set my timer are 3 sec on and 3 min off consumed a lot more water so after 4 days my 48 gallon was mostly gone, 3 gallon left at water change.

Today the other plants that were too small 5 days ago got enaugh roots to be transfered with the others, only 1 left to transfer.

Today i noticed some have started a strong root system and are growing quickly.
1 raspberry caugh, 2 green crack and 1 wedding cake are getting bigger.

Today was water change day, changed the feeding schedule to early vegetative as i noticed the larger one are showing sign of clacium deficiency.
Other than that they are growing well, one blue dream is struggling though.
Usual emerald harvest feed schedule at 2/3 strenght with 10ml/gal of H2o2 and 2ml/gal of enzyme komplete.
Ph at 5.6, ec is at 1.0, tds is at 490, temp is 17C
I topped after the 5th node the 4 larger plant.

What i believe is calcium deficiency

Some nice thick stem

Roots with new bubbler that i added in every tote to keep the remaining water oxygenated.

I also modified the humidifier, both fan failed, i guess the dropplets imbalanced the fan which caused stress on bearing or it didnt like being used at vertical, either way changed the design and now im using a pc fan to pressure up the barrel which push out the humidity, seems to work better.

Today i have put the last plant in the tent, it was thought to be dead but sprouted so i had left it apart until enaugh roots developed.
Im not sure if its a jack herer or a raspberry caugh.

What an impressive setup you have going! I have so many questions I don’t even know where to start lol.
I’m going to check out your other journals to see if my answers are there!
I also run the AC Infinity fans, well I’m halfway through my first grow using them. How do you like them and how long have you been using them?

 

[tokes]

Dude your set up is beautiful!

I have used my a infinity fan for one harvet so far and t works great, just for air though, i tried to pass humidity in the fan and the water was dripping from the seal on the motor side but i like the controller it help maitain setpoint in my tent.
