I just bought the autopilot f90 chiefly due to the praise and long use @Renfro has given to his autopilot models over the time I've spent on riu. I really haven't read anything bad about them (outside of it not being the cheapest piece of equipment)

Do you see the bulb in the middle of the first pic? It isn't easy to make out, but compare it to my pics (which are a littler easier considering the loupe used). It is more short and circular compared to the second pic which is more pointed (again not the easiest to make out). You have to look...

Some of my own examples of male vs female using a loupe. I typically check the plants every other day once I see the preflowers starting. Pic 1. Female pic2. Female pic 3. Male The white hair in first pic, tell tale female. Notice the boy is short and squat compared to the girls? They are the...

Not to go against the grain or anything, but it is entirely possible to tell the sex through preflowers alone. I cant tell from your pictures but I routinely sex my plants by the preflowers, long before clusters or actual flowers. Only thing is that it is not as exact as sexing through just...

I asked cause of all the information out their regarding the claim that a HVAC system designed for batts or similiar insulation is (according to internet sources, so validity idk) something like 40-150% oversized when placed in a SPF room. Since most of the information and advice is given based...

I am about to start on a shed build much like his with closed cell insulation throughout. Can you get away with a smaller minisplit that can cover the heat output of the equipment, or do i still need to go by the standard recommendations of btu based on size of the room + equipment? I am curious...

You should definitely put it in the shade or a shade tarp over it or something. That is going to heat up pretty quick I'm sure

I've never grown with nutes outside of top dressing on soil so that is going to be my real learning curve. Never grown in a tiny height requirement either but I think that is under control if I flower early and lst

Those are some nice looking plants

I am thinking about adding a similiar sized box to my next grow. Itd be a plexiglass box sealed up and like 4'Lx2'Wx2-3'H and use the the excess side light from my main cmh lights over the main grow. Just a thought and all these ways others have grown is giving me inspiration.

Did you have to go 12/12 from the start to keep them small enough?

Did you feed nutes or just str8 soil the whole way? Was it alot of work to keep them under a 3ft table height wise?

Was that soil? Jw

That got a laugh for sure lol

I am curious what kind of tiny areas people have successfully finished a crop in. Like did you go from clone to harvest in a 2x1 tote? What size fan/light did you use in your little space? Or something along those lines, not so much that you grew a crop in a solo cup you kept in your climate...

I was just reading nd it looks like most of the time ethylene buildup only really occurs if your using a combustion generator as it puts off slight amounts of ethylene and other gases along with the co2 your wanting

If the room is 100% sealed, it 100% requires you to bring in fresh air and expel the ethylene. Your plants will very visibly deteriorate if it builds up

The goal is to clear the ethylene buildup which the plants and organic debris naturally produces and can buildup. I'm not sure how quickly that happens and it is variable but it doesnt hurt anything to clear the room once a night, or a couple times over the night. Could run your exhaust fan for...

I ran a 5x5x7 tent as well for a while. In my case I never had smell issues until a year later when my filter was failing. I had the filter in the top of the tent connected to a duct fan that pulled air from the tent>filter>outside. In this way negative pressure was created so no smell ever...

I've seen alot of people use a sealed automatic damper and use exhaust fan with filter to clear the room at night. That is how I plan on doing my room when I get my new place next month. I'd probably pull air from the ceiling through a duct to be cooled by the ac? Not sure how the portable ac...
