They always look like this for me at this stage. So neat and healthy.
In a month they’ll all be falling over each other or cable tied together or with the tent walls.
Fed them 3 times already today.
Also treated them with Neam. Only a couple pf mossies and houseflies in there but sure did help out with getting the humidity up as high as 58% earlier.

I think the humidity issue might be from the AC inlet which also act as a humidifier pushing in really dry air constantly in the tents?Humidity still an issue - a decent 70%+ with temp 23c overnight. But lights on - back to 31c (fine) 40% Rh - too low. I want 70%.
What a weird problem to have here
Girls look banging though. Greedy hoaries.
Fed them breakfast at 5.8 and 2.55. Can see them going to 4 feeds a day.
I wonder what I can get the yield to? Went an oz off the Strawberry solo but that’s very beatable. Average that its over a pound. Average 1.5 oz x 18 is 27oz or 750g
But average 2oz - imagine that? 1kg out of a 4x4 in solos. That might even pay my electricty bill for the next two months
Ah the dreams you have in veg
Nick
One way to sort it is having a lung room which get humidified, its way easier to get a stable environment with a lung room. Another solution is running a humidifier constantly in the tents.

Yeah the tent really isn’t air tight and the garage where it is is mostly open. The Rh outside the tent is 70-80% I think its because the cold but not super dry air is chilling the water overflow that sits 4-5” below the sensor. I reckon I move the sensor to canopy height I’ll get a bump. Failing that point the inlet for the AC upwards slightly.
Will see how that goes. Playing pool with & Co for now

Sooo moving the sensor up closer to the canopy level did indeed raise the temperature. 31 became as high as 38c
It also lowered the Rh to as low as 38. The lines actually crossed last night after I moved the sensor
.But I angled the cool air intake up a bit about 2 hours ago and I’m OK with it. I just need not to run out of gas
Nick
That concept is exactly how I work my tent. Cold AC air on the bottom and a cranked up 6” exhaust fan up top to draw it up. Based on my readings the fan beats the weight of cold air. It works great.Irrigation is in. AC is connected.
15 emitters run with identical pipe lengths and skewered into the pots. Waters in about 3 minutes. Yayayayay YAY!
AC - not sure if this will spark debate cold sinking, warm rising. But cold is going on the bottom here.
I have run 6” duct from the AC to the lower, front right tent intake. In the upper rear left corner I have a vertical 6” inline sucking airflow from low to high and exiting the tent into 4” ducting that returns in a reasonably closed loop (builders can do properly as its on their list) but opposing corners in and out in the tent for max airflow.
The idea the cold air enters the bottom at plant level and sure it warms but it will also cool as its sucked up to light level.
Its a bit messy still. But seems to be working at the moment.
So now its just Co2 and change the lights over. Should be able to get both done today.

Needs some work….
Lights on at 8am. Hit 42c last night. Humidity down at 33%.
I have a bit more AC optimisation to do. Need a second pair of hands to do it (& Co is too short!)
I have a humidifier coming tomorrow maybe. Hopefully burning off more will also cool it.
When I flip I’m going to switch off the CMH. Its cool light better suited to veg anyway. That will reduce the wattage by 315w or about 25% - better for temps and bills.

Isn’t this why you use CO2, so that you can operate safely with higher temps? (It’s a sincere question, I don’t know from CO2).Needs some work….

Yep you can run higher. You need Co2, heat, higher EC, decent humidity great light to benefit from it. I have all but the RH here. Its still a bit high for me. 35-36 would make more comfortable - but to get the sensor at canopy level its direct under the lights, tried shading it a bit with irrigation piping but think its running a bit higher than it is. Maybe.
I don’t have a drop down probe type thermometer spare to better test. Going try a little hydrometer like you can use in cure jars for a second opinion. Have a bag of them somewhere.

They are all mostly showing signs of heat stress today. Raised the lights to the max a few minutes ago. Might be a short veg just so I can lose a light for heat and keep heights down.
Hand misting them too. Meh.
Seems a lot like work to this me, now. Jon can I have a bit of your “I’m bored just looking at monster buds waiting to harvest” please.

Nice manipulating the air in there guys! Big change!

I’ve got it down to 36-37c and averaging close to 60% humidity. By hand misting every 90 minutes or so.
So the little humidifier I have coming will lock that in. But I think if I move the cold air intake and rebuild the hood on the AC I can do better. The Tropicana Poison clone isn’t liking it and the Hulkberry SIP its time to say goodbye I think. I can swap some stuff in. Not sure. I need some space for the humidifier - think unless a dramatic change in the next 12-16 hours I’m losing them both.
I’m keen to flip to be honest. The Auto - Strawberry Cheesecake - is only on day #22 though. Ideally want her close to flower when I flip the others. Just for neatness as much as anything.
The worst hit plant now from heat stress is the GG SIP (Right, middle tallest) Its weird she was much further out the light than her sister but she looks like a different pheno. The leaves are far more spikey sativa style. Sis is showing more purpley indica as our last lot all were.
The rest much of a muchness really.
EDIT - moved the cold air to a top hole and then ran the duct down to op top of the fan. Down in the 35’s! I think with a spare inline I have and a hood rebuild we can that down another 2-3 degrees. Be cold af at night

Wow Nick, nice! The growth on them in just a couple of days is tremendous.

Yeah they’re going strong apart from that Gorilla SIP. Its weird.
Think I have the environment under control mostly. Maybe I’m about to see 34c for the first time in a few days. Whoop whoop!
Flipped the hood on the AC and got a much tighter fit.
With a humidifier - its 80% in the lung room - how I get below 40% in the tent gives an idea of the heat the lights put out. Its 28c 80% Rh and raining in the carport/lung room. Inside 35.8c and 50% right now.
I think ditching the CMH in flower and some optimisation I can get to 30c and 55% in flower. That would please me muchly given the extremes of temps I have.
Not sure about using this tent/light again. I’d like to try a single plant SIP with SCROG or whatever. All neat and tidy like I see others doing. If, its a big un, if I have the environment dialled in maybe I’ll use these lights again. Depends on the cost of the juice.

I was gonna say that maybe switching that light for an LED would help solve your heat issue, but I know how into the idea of those lights you were….

Do you have the lights in a vented hood like this? It's really hard running hid's in tents without a vented hood. I usually mod mine like this so I can run extra bulbs and spectrum. The other one got a CMH socket.

As Taylor Swift once said, "don't say I didn't, say I didn't warn ya."
Yeah but me and advice?
I just… Shake it off
More bulbs?! More? Are you mad, Sir?
They came with all sorts pf warning about not modding them like that - new materials, hood design etc. a Scandinavian mate was all for it having used them there a lot.
A couple of photos below of them in situ. At the back right you can see the AC delivery pipe onto the fan (which also distributes the Co2) the inline back left circulates the air nack to the sealed hood on the AC unit.
I think I’m just a day or so to getting it dialled in. Once its done its done. The outside air isn't changing more than +/- 5% year round.
Its been fun. The lights draw 218v 11.4A 18 hours a day. That includes two Mars Hydro FCE4800s. Sure I can figure out the cost of that with my utility unit costs?
The FCE’s just went off and now reads 7.4A wow. Just off double the draw

Not many strains can handle it but the most I've ever run during winter months were 1200w under that hood. Only needed a little heating during lights out. Dual filters and exhausts, one from the hood and one by itself and everything got vented outside. The lung room got down to 12-13C ~55F.Yeah but me and advice?

Opposite problems!
Yeah I don't regret it yet. The heat stress is spreading despite misting often. Not often enough though I think. Humidifier arrives tomorrow. $15 6” Inline arrives day after. Those two arrive and it will be fine. Sure of it. But yeah I could swap back to my little 320W LED and be OK in 24 hours and just run them out to flower and harvest with minimal input. But there’s not much challenge to that.
Down to sweet 16 in there. The Tropicana Poison is back with her fellow clones in the veg tent. She can gonin the main grow when she’s recovered. She was just too small to go in there really. The pythium afflicted Hulkberry is out. I’ll be sure to keep the Solo SIP for another day. I’m not going to replace them - the spares are already in 1 gallons and are going in the main grow and I need a bit more space for the mister.
Just need to coax them through the next two days. Maybe turn off the CMH. Decide in the morning.
