Hello everyone, and thank you for taking the time to read my thread, this will be a long one, riddled with beginner mistakes.

I have been giving a Female "Crit" on July 24th. Grown outside surrounded by a few sisters, it had been a week since it had been promised to me.
With this information, I assumed it was around 14 days old, or older.

At the time of offering, it already had a few completely yellow leaves, which I promptly cut but left some that seemed like they could recover.
This is what it looked like when I left her outside for a day or two, while I was waiting for the store to open to buy the equipment:

So, I set out to do some research. While it is legal where I live, there is a clause in my contract against it. Therefore I cannot exhaust and risk smells getting to the outside of the house, nor stink up the inside.

This led me on a futile quest for a cheap, closed loop solution. I thought I'd buy this: Mars Hydro TS1000 but called a local shop that recommended against the LED and suggested I go for 315w CMH (and as far as I can read in these forums, this was a good decision, despite the heat problem). I explained the issues and that I wanted a closed-loop where no air would go in or out, only circulate. He sold me a full kit, gave me some fertilizer and another "super-something 1-something-something" I forget the name of, for the rest of the yellowing leaves.

Once I put everything together:

This is the setup at the time of filming the first video:

1629494831333.png

After a while, temps were absolutely insane, at a scorching 33°C / 41% R.H.
Since the plant was still very young and didn't smell, I opened up the tent and put a fan in front of it.
This would now be exhausting hot air in my air conditioned bedroom, which was at 19°C near the AC, and 21°C near the tent. (AC is across the room, exhausting to the outside.)
I figured I would lower the 4-step dimmer on the ballast, and at the 145w setting, I was able to reduce temps to:
23.5 / 74% R.H. Day with the tent open
28.1 / 80% R.H. Day with the tent closed
21.7 / 45% R.H. Night (tent closed, obviously)
The local shop suggested another fan, so I bought him a booster fan and a pole-mounted fan, and I thought it would be enough CFM to cool the CMH light tube on its own like this (not my setup):

1629495658691.png


It didn't take very long for me to realize the booster fan was ABSOLUTELY not enough.
Plus, some of the research I did told me there is a need for fresh, CO2-charged air, and a perfectly closed loop with no CO2 generator is simply impossible.
So, I asked a few more questions regarding the filter and apparently even if it is exhausted in the house, it should not smell.
Okay then, I trust you, local shop owner. Used 2 old usb desk fans with a usb hub, opened up two passive intakes at the bottom of the tent, and exhausted this in the bedroom.

The setup at this point July 30th:

1629496957242.png

Trimmed it on Aug 1st, and switched to a 12/12 schedule because I read that you should put em in flowering as early as 14 or 16 days Here (and this guide is what I've been using ever since):
1629497033903.png


On August 8th, a sister was given to me as the potential owner could take take care of it. It was put together with the other one, and as such was immediately switched to 12/12. I also setup an old phone as a camera inside the tent.

August 16th, started reading up on monster cropping, training, etc. and tried to apply some of the things I learned. Also, at this point I returned the dimmer to 315w, because I realized I put these babies in flowering way too early and I want them to benefit more from the stronger daytime light:
1629497741237.png

1629497751022.png

At this point, I keep the tent closed all the time, daylight temps are 28.4°C / 48% R.H., night is around 23°c.

This is today, August 20th. Note, some of the bottom leaves yellowed where some fertilizer water spilled and dried.
I need to be more careful, maybe my watering can is too big. Any ideas?
Also changed the training wires to something thinner and lighter.

I believe most of the vertical growth is over at this point, so I should be focusing I getting a good flowering season and a successful harvest.
I am thinking about buying some polyester trellis netting for training, and I ordered a mini air cooler (cool water evaporator) to lower the temps and raise the humidity levels.

And so, here we are.
As you can see I am not an experienced grower by any means.
I would like to know what you think about my grow setup, what would help me get the biggest yield with the plants what I'm working with, and how to avoid any further mistakes.

Thank you all, and have a great rest of your day!

Well. The equipment should work well. I think you should invest in some seeds. And do regular pest and fungus control. I'm not going to sugar coat anything for you. This grow is not going well. However. You're in the right place. And it's good to get some practice. If you ask the right questions. And make an investment in nutrients and quality genetics and some pest control you should have some good weed in a few months. Happy growing.

Thank you for the feedback Ponky, much appreciated!
With the current heat wave and high CMH temps, I have been running 29°c / 50% R.H. daytime | 21°c / 45% R.H. nighttime

I have been looking for pest ever since the beginning, I had noticed a very small amount of tiny bugs when I brought them both from outside, but nothing after the first few days.
Thankfully, I believe there is no mold.

They have not changed much visually from the last pictures, however the trichomes and pistils are much more present.
We are on day 22 of the flowering stage, here's a closeup of both of them.
If I understand correctly, from this point, I should be waiting another 4 to 6 weeks before harvesting the first one.
I read that most of the pistils should be brown, but I must be keeping an eye on the trichomes so they don't turn brown.

I probably wouldn’t worry about getting the trellis net as your plants are very small and won’t require any support and there isn’t any branches to tie down. You have all the right equipment so your next grow can be a successful one. I wouldn’t put to much effort into these as you won’t barely harvest a couple buds but take it as a learning experience. Buy some quality genetics and some living soil and organic dry amendments and you will be growing fat bushes in no time! You weren’t givin healthy plants and you may have made it worse by overwatering and other environmental factors but there so many awesome growers here who have helped me on my road to becoming an indoor cultivator. Don’t get discouraged and do your research and keep trying!

So we're 10 days later from the last post, as suspected they have not grown much more and one of them looks like it will have a very small yield.
I think I should harvest in one to three weeks, but I'm wondering about the exact day it would be ideal.
I also didn't realize until recently, but I didn't have any "bloom" fertilizer and only "growth", so I stopped giving them any since last week.
However since it's so late in the flowering season, I wonder if it would be a bad idea to introduce fertilizer at this point.

The sister was put in bloom 1 week later, but it is much smaller.

So basically:
-when should I harvest?
-is it too late for bloom fertilizer?

I would go for 9 weeks. Feed bloom up 6.5 weeks. But don't stress about it. They won't yield much. Buy your next batch can.

So I got some bloom feed, I watered nute-free yesterday. Next watering will be with bloom and will keep feeding every other watering for the next 2.5 weeks.

Looks good. The leaf damage is from thrips. But Looks like it's gunna smoke.

U need to 86 that cmh ASAP, go take it back to the asshole that sold it to u and tell him to put it a foot away from his face and turn it on for 12 hours🤣🤣🤣. I’ve done it before brother and it’s possible to do a run with a cmh but it gets F’in hot in there and they can’t get to close to that light or they’re toast. With an LED u can keep that tent at 86 degrees and 60% humidity, and they can get stupid close to that light and they’ll be fine lol. U prolly wont even need any cooling and if u do get a small portable AC, ur gonna need it when ur drying ur buds so u can keep it at 60/60 in ur tent. And as far as for keeping down the odor at ur place, put an air purifier in the tent, one that has a charcoal filter, u can find a descent one for like $80-90 on sale. There’s a company called ona that makes stuff to keep the loudness down as well, u can get that on Amazon. Definitely get an LED tho bro!!

Ah yes, I forgot to mention I mitigated the heat problem during the heat wave by attaching my portable AC directly to the air intake, and exhaust the AC in the rest of the house (humidity is condensed into a bucket).

That metal duct is sweaty AF, I had to put a towel under it, but I need to get an insulated duct for next year so it doesn't rust.
1630943224250.png

Now that the heat wave is over, the AC is a bit further from the tent. (This close at night, temps went all the way down to 14.5°C.)
Obviously, I allowed for plenty of airflow with all windows open and strategically placed fans.
I'm keeping a stable 25°c during the day / 19°c during the night, and R.H. is hovering between 40 and 55%.
I bought bloom yesterday and fed it today, but apparently, I was missing the bottle of part "A" (5-0-6) of the growth nutrients.
I have been feeding my plants only the "B" part (1-5-6), so they were drastically missing nitrogen.
Stay tuned for more ridiculous mistakes, we still have harvest, drying and curing, so much can still go wrong! :D
