Run #5, Grimm situation in the big tent
- Thread starter flylowgethigh
- Start date
Nope, still 18/6 and they are up to 370 umoles. I want more plant, so it will make more flower. I am guessing a 3-1 stretch ratio, 4 max.
Thanks. I can grow plants, but making the flowers glisten is the trick that still eludes me.

I'm sure these will be frosty gals, they look great! You should see 1.5x stretch I would imagine. It's always a guess though until having a grow of the strain under belt. The C99 I have going stretched way more than I thought they would, freaking shrubs.
I really like the look of the Killer Queen leaf. That's my fav so far..

LOL, bushes are my thing. And it appears that KQ is no skinny leafer. Look at how bad that OHSK stretched, or the KCH from run 3, so I am leary. Overwhelmed a BH plant in there with the KCH tribble. That is a risk with running different strains in the same tent.
I sometimes wonder if the inside air circulation fans are hurting the frost, and that they should be turned off in mid flower or so. I think managing the temps with forced filtered air is my next challenge.

I run my in room fans right through harvest if that helps.

Do you mean that the trichomes physically fall off from the airflow, or just unhappier plants from "wind stress". Anyway either seems unlikely unless it's some crazy mega fan.
Just choose frosty strains. And take the photos with lights off flash on
I do not blame the genetics for my bad environment.
So the lights are in the process of changing from 18/6, at 2 hour reduction per day. They are at 14 now and will be fully flipped tomorrow. The KQ needs to stretch some to get the leaves unlocked. The other three are doing well.
Edit 4/3: Fully flipped to 12/12

Chugging long...
I noticed the light was malfunctioning last night. When off, there were still elements burning. I replaced the whole light with the one from the other tent. Let's hope the plants were not too adversely affected, but that cant be good as they had just been flipped a few days prior.
If it ain't one thing, it's another.

Ever notice how it's 'always something' when growing pot inside? 
I'm sure they'll be fine, looking good so far!
I just germed 4 KQ females last night, couldn't wait for a whole new run.

They won’t care a bit, you got them ready to go. To a frosty finish
Luckily the plants were not so big, and I was able to change the light with them in there. KQ in the back right hole still needs to stretch more and sort out the branches from my bad FIM job. No real dominant plant yet, so BH may have a chance this time.
Normally the SWICK soil is dry on top, but I also feed and inoculate by top-water. Cause I had them, I put in some yellow stickies, and see some fungus gnats. I have the Arbico Organics catalog out...

Regarding the light issue, Growers House is saying there were some ROI E680 and E720 lights with the same issue I have, with the lights staying on partially when shut off. There is supposed to be a new booster for the driver that they will be sending out. I have gotten nothing but great customer service from Growers House. Consider that when you buy equipment. I told them the light was taken out of the tent and not holding up the run, and mentioned I am testing a Mars FCE with remote control in the other tent. The customer service rep said not having remote control was one reason they didn't carry the Mars lights. Remote control is nice - and I like the Growers Choice controller. A light controller and the SWICK system lets me go away for a few days.
I think my light issue may have something to do with the controller and the sunset/sunrise feature, makin the solid state components in the light lazy. It may be the internal driver circuit, as there is no external driver like a Mars light. During the last run I had this issue, and I 'shocked' the circuits with the controller going from ON 100% to OFF a few times manually. It worked for a while. The light I have in there now has given me no trouble.

ground up mosquito dunks on the soil surface works every time for me. Give them a try...don't waste your time with mosquito bits...that stuff is bs.
i'll second, dunks for the win.
i may have missed it, but how long did you veg?
they look healthy at any rate.
grow on!

I flipped them a few days ago. This tent has been a torture chamber all along since I put it up. I ripped the zipper being an oaf, it only had one of the bottom screens that could open. It got hot and dirty.
No more, and these are gonna be some happy plants. The little winged bastards are dying on the stickies, but yeah I need to order in some IPM.
I have wanted to put forced filtered air in since I put these up. I finally did it. The internet hotspot is dead, so with all my newly found life, I have been busy. This idea works great, and will allow me to keep the VPD rock solid and under 78*. I also am able to jack up the umoles higher. They are at 600 now, with the VPD right in the veg range.
The next step is one of those AC units that blows the hot air outside through the window (gold curtains), to keep the lung room perfect.
Filtered forced air: exit fan at 7, intake fan at 3, tent sides puffed out. Is there a downside to positive pressure???

Abstract
Plant responses to reduced air pressure: advanced techniques and result
https://pubmed.ncbi.nlm.nih.gov/11538810/
Knowledge on air pressure impacts on plant processes and growth is essential for understanding responses to altitude and for comprehending the way of action of aerial gasses in general, and is of potential importance for life support systems in space. Our research on reduced air pressure was extended by help of a new set-up comprising two constantly ventilated chambers (283 L each), allowing pressure gradients of +/-100 kPa. They provide favourable general growth conditions while maintaining all those factors constant or at desired levels which modify the action of air pressure, e.g., water vapour pressure deficit and air mass flow over the plants. Besides plant growth parameters, transpiration and CO2 gas exchange are determined continuously. Results are presented on young tomato plants grown hydroponically, which had been treated with various combinations of air pressure (400-700-1000 hPa), CO2 concentration and wind intensity for seven days. At the lowest pressure transpiration was enhanced considerably, and the plants became sturdier. On the other hand growth was retarded to a certain extent, attributable to secondary air pressure effects. Therefore, even greater limitations of plant productivity are expected after more extended periods of low pressure treatment.
Factors Affecting Transpiration in Plants
Factor # 5. Atmospheric Pressure:
https://www.biologydiscussion.com/t...ctors-affecting-transpiration-in-plants/49049
Atmospheric pressure affects transpiration, because it has influence on the rate of vaporization. When atmospheric pressure is high, the rate of transpiration is low. However, in any given locality variations in the atmospheric pressure are too slight to have any considerable effect upon transpiration rates.
Plants growing in high altitudes have distinctly lower atmospheric pressures, and as such, those plants have significantly high rates of transpiration, if other environmental factors are not limiting.

I have taken the forced air to the next level by cutting a hole in the center bucket (control box) lid, added a bucket with the bottom removed and 8 holes cut along the top - stacked onto the control bucket so the holes let air out - and put the hose from the filtered air box into the lid. The water in the control box is evaporating, cooling the water, and the air that comes out. The cool moist air is blown sideways from the 8 holes, all around the bottom of the tent. This has made the temps and humidity rock solid. The water in the reservoir stays cool. My 4 x 4 tent can only take 500 watts and stay in thermal control, and the 'swamper' drops 3*C with the lights on, 1*C lights off.
This is a huge improvement, and I expect to see improved results.
Got some Sf nematodes. treated the soil tubs and will treat the 4 soil bags. I didn't top water for a week or more to dry out the top of the soil and thwart the fungus gnats. The plants seemed happy anyways. I top watered in some microbes and feed, so the soil is moist for the nematodes.

I can't believe that I have solved the biggest problem facing humanity, and that is the heat and humidity in a tent, and all I get is crickets. Well, that and happy plants too at 13 days since flip:
The fungus gnats are a thing of the past also. Sf nematodes and yellow sticky pads took care of them.
I have some 'Great white' microbes running around in the soil now too. No signs of flowers yet, and they can add another three feet for all I care. There is room. still at 12/12.

They are starting to show some flowering. I am hitting them with Rootwise 'Biophos' microbes and some more feed today. Gnats are long gone, but my reservoir smalls like bacteria. The water in the tubs recirculates due to the waterfall control box. Organic soil and the critters in it have smells we humans are sensitive to.
I wouldn't mind another couple feet of height.
