Second the moisture stress suggestion. In my experience, when soil is totally dry it can take about 1/4 of its total volume in water, so that would be more like 750 mL if it's totally dry. And if the soil has dried out to the point of being hydrophobic (water runs off easily instead of soaking...

Agree on the chilies. I feel like hot peppers and herbs are some of the few crops where you can get enough usable yield in a small space to justify growing in a tent or grow box...

Ty for the detailed explanation. I have no need for an intake fan in my setup, seems like one of those things new growers see advertised by companies selling grow equipment, and automatically assume they need one too...

At what point do you need to use an intake fan in addition to the usual exhaust fan? Is it solely dependent on tent/room size? Is there any specific benefit to adding an active intake fan, vs increasing the size or number or passive intake ports?

I think you are way overthinking this. Unless the roots are sitting directly in water ala DWC, the amount of dissolved oxygen in the water is pretty irrelevant. Use a well-draining medium and don't over-saturate it, and your roots will have all the oxygen they need.

On my current grow I'm using a thick layer of cannabis leaves as mulch and it seems to help keep the top soil moist. A cover isn't really that bad with a SIP since you'll (hopefully) rarely be touching it. In the past I've used a piece of panda film with a slit cut in it, so it can just slide...

Trichomes are not the best indicator and the easiest way to harvest too early. Your plant looks great, give it another week or so and check back in. You'd be surprised how much it changes (for the better) over the next couple weeks.

This is a fair point. I have mine pointed in the space between plants, but any branches that lean into that space do get wind burned over the course of the grow...

Might also consider a tower fan. Small footprint to air movement ratio, and most of them have an oscillating function.

Huh...it might help to at least get the dehumidifier out of the tent and into the room. AC units also remove water from the air, and the dehumidifier exhausts hot air which you might want to spread out across the whole basement rather than having it concentrated inside the tent... Good luck!

You can def use the dehumidifier to bring the RH of the room down (it'll work better and be easier to drain when it's outside the tent anyway) but not sure what the best way is to get the temps down in that case. That sounds very similar to my unfinished basement. I have a dehumidifier but no...

I think you need to focus on getting the overall basement climate right, rather than treating the tent as an isolated space. I would start by asking what the typical temp and RH is in your basement (or whatever room the tent is in)? For a tent grow in a room, the best approach is to get the...

I understand the intent of following VPD, but running in the high temp/high humidity end of the spectrum would sketch me out. I'd much rather flower with temps in the mid-70s and RH of 50-60%, than with temps in the 80s and RH of 70-80%.

Almost 10 weeks. These were like 6 inch tall clones when I flipped them, the stretch is real...:o

The Ethiopian growbox grow continues...

Can you instead condition the air of the room the tent is in, rather than having the AC unit inside the tent itself? If any piece of climate control equipment is cycling every few minutes, it might be oversized for the space, working on too small a volume of air.

Looking good! Still a fair amount of white pistils when you zoom in, I'd think you're more in the "check back in two weeks" range. And just imo, nothing you do for 3 days at the end of the plant's life is going to have a noticeable effect on the end result

What's the RH of the room the tents are in? The inside of the tent is almost always gonna be a little warmer and more humid than the surrounding room, and the faster your exhaust runs, the closer the tent temp and RH are going to be to the room temp and RH. If you can slow down the exhaust fan...

Oh dang I probably would have just left it. You basically just super-cropped it and gave yourself a more even canopy. And yeah agree with above, I don't think the humidifier should be blowing directly on the plant.

I think at this point you'll be better off super-cropping. That's where you crush the stem and fold it over at a 90-degree angle. It definitely takes patience if the stems are hard, sometimes you really gotta work it between your thumb and index finger knuckle for a while to break up the fibers...
