Very nice, love the DIY exhaust setup you've got there. I'm a FF OF/Nutes person myself but I'm able to use a 270w in a bigger cab. I don't have much height either and use a mix of finning, topping, supercropping and LST to keep them short. The good thing is that weed is pretty resilient and can survive even if you mess up.

cool setup it looks good for veg i guess but seems kinda small.. i would worry about heat. are you gonna run full cycles in there?. im not doubting you i just know none of mine would have made it in a box that small good luck keep posting

Looks great! I'll be watching.

Thanks. I have yet to test the effectiveness of the carbon filter but it pushes a lot of air so regulating the temperature isn't going to be hard. What are the dimensions of your cab? I was debating between a 150 and 250 watter but since I was concerned with heat, I opted for the 150. I could have run a 250 with a cooltube but I really need more vertical space to make better use of it.

Since I'm growing a bunch of bag seed plants I am experimenting with topping, LST, and FIMing to see what yields the best results.

Thanks. Yeah, it is pretty small. I've got 22" from the bottom to the bulb. Since they are in smallish pots, they aren't going to get huge and I plan on LST'ing them once they start stretching during the first week of flowering. I am learning as I go, so I'll deal with the height issue when it becomes a problem.

I'm not worried about heat at all. The HPS cabinet stays cooler than the CFL cabinet. With the fans on and door closed, it gets maybe 2-5 degrees warmer than ambient room temperature.

Thanks. I'll keep this updated as much as possible with pictures weekly.

everything you are doing with this grow looks well thought out. you already have inspired the engineer part of me with the exhaust and the cab in general. you are doing great

in such a small space, you might benefit from bushmasters, it prevents vertical growth and promotes side-branching. link

Thanks a lot PG. I must admit that I did have a lot of fun designing and building the cabinets. We'll have to see how well everything works once the plants get further along. I am going to keep my healthiest female as a mother plant in my veg box and switch the other bagseed to 12/12 since they have shown preflowers. I'm still waiting for one of the plants to show sex but so far I've confirmed 4 females and one male so far. Pretty good ratio if you ask me.

Thanks for the link to that interesting product. I didn't know such a thing existed. Pretty crazy that is completely halts vertical growth if dosed high enough. Unfortunately, $100 a bottle is pretty steep for my budget.

Hey dude, you can buy an 8oz bottle of bushmaster for like 30 bucks shipped.. it is EXTREMELY potent, you only need a very very little bit.. especially for such small plants.

Awesome grow, amazed your able to keep temps low enough. I'm a little bigger than yours with a 150w and i had to run an ac line to it heh ;p

Oh, I didn't really check the price out. The original post on the link mentioned the bottle cost him $100 and my jaw just dropped right there. I'll look into it if the LST and FIM is effective. I appreciate the advice +rep.

Thanks for checking out my grow and I'm glad you like it. I think the major reason my cab stays cool is the fan being right next to the bulb drawing all the hot air directly out.
