Day 28
It's been far too long since our last update. My apologies.
Things have been busy in the garden. I blame the lack of updates on the ease of use with the SIP
Please excuse me for pulling this from my other journal. with an edit or two it led to an amazing conversation in my other journal worth checking out.
"The other night I stayed up late! Reading all about VPD, soil moisture, water vs. nutrient uptake and how all of it works together.
I sat back and looked at what was going on, comparing what I was seeing to what we're aiming for.
That led me to making a few changes to the environment in the controller.
I realized that at the temps we were reaching keeping up with humidity is much harder to do obviously.
Luckily for us the environment outside the tent has the ability to be much cooler. Thus, lowering the max temperature, we are able to achieve in the tent.
To do this I simply shut off the heater yesterday during lights on, let the temperature in the garage drop and let the
the lights do all the work. I did need to drop the intensity of the lights to 50% yesterday to let things cool off a bit.
Once it finally did, we were able to reach the humidity and VPD we were aiming for.
I brought the temps to 73F. Humidity then rose to over 50% and we achieved a VPD of around 1.1 like we wanted
I had to set the inline fan to only go on when the humidity limit (55%) was reached otherwise I had it shut off so not to constantly vent out the humidity we had just built up.
I also decreased the high heat limit so the inline fan would turn on at 74F to ensure we maintained the numbers we were looking for.
With those limits set it ensures the inline fan turns on periodically to refresh the air in the tent like were supposed to.
At lights out I turned on the heater on low power and set the thermostat to max. It kept the tent temperature around 64F. The temp of the garage was about 67F.
Then I turned the thermostat down to the point where it clicks off and stop. We now have our limit set to maintain the temps during lights out.
At lights on today I turned the off moved it out the way and turned the lights up to 10 were now back into the parameters we want.
One thing tackled on to the next.
I feel like even tho I've been in the tent and practically working exclusively on the grow, I've been sitting idle.
There was more that could be done.
The Fungus gnat situation has turned into the 100-year war. But I do feel there is an end in sight with my latest moves.
I noticed so many gnats on the small pots at the pot the bottoms.
I put the sticky traps in around the bottoms of the pots intertwined between the pots and it helped but then I saw it and realized it.
I never put perlite in the bottom of the pots when i transplanted to 1 gal plastic pots. And the little bastards were using the bottoms of the pots instead of the tops it seems.
A trip to the local hardware store was in order.
I picked up a couple of things that I feel are going to make a big difference going forward although simple and everyday things.
Sometimes it's the small things ya know?
- Perlite
- Diatomaceous Earth
- Spray bottles
- Pump sprayer
- PVC cutter (Finally)"
...Annnd we're live again!
I finally did away with the chimney stack on the SIP. I wanted to find a Santa to put on top of it for a picture but to no avail.
@Azimuth I'm sure your finally relieved to know my bucket is finally OSHA approved
I did however after removing the dry layer of soil on top that had gnats crawling throughout it add a layer of DE to the top of the soil. Then I added a layer of fresh soil that had been treated with SNS left out to air out and dry then brought in to finish drying and warm up. I then added perlite and myco to the soil and this was put on top of the layer of DE. I then added a layer of DE onto this fresh top layer.
The number of fungus gnats at the top of the soil has decreased.
Tho the res seems to be the new place all the cool gnats like to hang out at.
So, I added a piece of screen to cover the hole still allowing fresh air and water to past through but make it more of a challenge and deter them a bit.
I have also been continuing the training with the quadline. It is becoming more difficult because she seems to now be wanting to stay squatter and she has started to stagger her nodes.
Her branches are also much thicker than anything else in the garden so extra care has to be taken not to snap any limbs.
She is already bushy again and looks like she could use another haircut to keep things a bit cleaner and easier.
I flushed her res. tonight with R/O water PH to about 7.5
I made the mistake of feeding her in her res at the last feeding for the tent and it was needed to flush out as much as I could. This also allowed for more of the mosquito dunk bits to come out and a not so healthy-looking film that was in the water.
I flushed it out with a gallon of water until the water was clean and the res was full.
NO MORE NUTES EXCEPT CAL/MAG IN THE RES!
With this type of SIP and the nutrients we are using I do not believe it to be a good idea to exclusively use the res.
Feedings must be done through the soil and only water should be allowed to be absorbed by the soil.
I look forward to results from the 1 bucket growbucket style to see if results are any different regarding nutrients in the res or feeding through the soil only.
I think it makes the most sense to feed the soil water the res.
Her clones look very good all still alive none have dampened off and I even think 2 of them might have pushed the growth tip out a bit more since being in the bucket which is usually a good sign.
Although I have yet to confirm roots.
Also, the leaves look to be yellowing a little bit after a week which is also a good sign that they may be using those leaves for nutrients as they establish themselves.
The hope is they all root soon as the bucket is needed for teas that I would like to brew as well as the space that it's taking up. I would much rather fill it with rooted plants.
Other than that, she's been doing her thing just making her way. If she doesn't start stretching a bit more, we made have to give up the quadline and just let her do her thing with another topping or 2 before flower as I suspect she should be close to it with a little more size to her.
