Knocked wall down to expand grow room

Just wanted to share my new setup.

I knocked a wall down to give an extra 4sqft of grow space and have double door access.

I upgraded to 300 watt vivosun LEDs over my chinese 300 watt LEDs. I am using a nanolux 315 cmh with Phillips green power 3100k bulb.

I raised my bar 1ft for better plant height and to avoid light burn.

The room I am growing in is around 7 foot 8 wide and 2.5 depth. Ceiling Is around 9 feet tall.
Winter
Ventilation is temp controlled and pulling outside air in, in the winter. (6 inch duct fan) 1 250 watt mini ceramic heater on thernoststat to prevent temps lower than 60.
Summer
6000k window ac with two 4 inch ducts ran and connected to furthest door.
Air Intake
1 active 4 inch duct on furthest door, 1 passive intake on furthest door.

Carbon scrubber and a 6 inch duct fan pulling hot air into my crawl space. I have 2 honeywell fans circulating air. One at plant level and the other at the canopy.

Lastly, I included a picture of my intakes. This is my current winter setup. I have my active intake connected to my 2x4 tent. I use this as a perpetual grow. I will seed start and then move my plants to the flower room. After that, I will clothespin hang dry my buds in the 2x4. The active intake pulls the odors from the tent.

Let me know if you can think of anything I'm missing or could do differently. I am really excited to get 4 plants going in here. I am hoping once I dial in the setup to pull a pound a grow, but I wont hold my breath

I am growing organically in 5 gallon fabric pots. Using roots organics dry nutrients, worm castings, kelp meal, molasses. Growing high yielding autoflowers.

Grow room max temps will be around 78 summer and a night temp of 73 ish. Winter will be around 74 high and 64 low.

Be careful venting hot moist air into your crawl space. You could rot your house.
1lb is possible yes.
Is the vivosun LED any better than the Chinese LED, Both Chinese no?
I would think about the actual power draw not the named wattage of the light and possibly use both lights as well as your 315cmh.

Definitely one pound, definitely!

Definitely understand your concern with the crawl space. It's actually a 5 foot crawl space, I live in colorado so everything is so damn dry. If anything a little humidity will help. Lol, very valid point that Vivosun is Chinese to. They are much better than my 300 watt LEDs from ebay, draw around 132 watts. The vivosuns draw around 135 watts each. All combined I am pulling 620 watts from the wall.

Why knock down one wall? By now you should be thinking of gutting your house for a massive grow. Why do you need a kitchen when you growing weed. You can eat out.

Very valid idea, I like your thinking. Well I do have a couple acres of land. I was considering throwing a greenhouse up. I am wanting to get a cultivation license. They are around 5 to 10k though.

Is your wife/girlfriend willing to do porn? I hear that pretty still much pays good. If not there's always recycling. There's some old dude around here that cleans yards for free. He makes about $800 a month at the scrap metal yard.

Porn is always an option, although I doubt my wife is on board for that. Side hustling is always the way to go. We actually are working on selling chickens, eggs, pigs, goats for extra $$$. Moved from the city to enjoy a country life last year. Turning into farmer John over here.

But in all seriousness....
I would ditch those crappy Chinese light and eigther go with CMH all the way or get some real Quantum boards. The price of the high quality boards is coming down a bit and the improvement on your grow will be quite noticible.

maybe 450 grams 451 if u are lucky

My goal was to switch to cmh only. The quality of light and resin production is on point. The LEDs are hit or miss. I have total of 3 generic panels from ebay. 2 of them are straight trash. One of them really produces, I managed 4.5 ounces on an Alien vs Triangle plant. Aside from that, I am unsure about the Vivosuns at this point. I haven't grown a plant from start to finish yet. My last grow I managed about 12 ounces from the two Ebay panels and the cmh.

Don't take this the wrong way, as I certainly don't mean this as an insult just advice. If you need to ask how to pull a pound, you likely won't. People that pull 1lb+ yields have done a lot of research, troubleshooting, and of course phenotype hunting, among a variety of other things.

A pound for you is certainly possible, but I don't know your strains, your soil set up, or pretty much anything that could help me to give you solid advice.

What I can recommend is that you hold off on tearing down the wall, ditch those LEDs and run all CMH and get another grow or two under your belt and take some notes. After the next grow or two you'll be able to answer how to get 1lb+ yourself because you'll have both the knowledge and experience needed. Unless you're building your own Cree/COB LED, then LED is a waste of money and is absolutely worthless.

Run nothing but CMH and veg longer. Those plants are too tiny, 4 plants at ~3-4ft high should net you a QP a piece. Start vegging your new plants now so you get a head start on veg growth, even crappy LED lights are useful for starting clones/seedlings and vegging plants until they get to be ~1ft tall.

You'll get there soon enough my man! Just takes planning and experience. As long as you're learning and enjoying yourself, you'll meet whatever goals you set your mind to.

Kratos thanks for the tips man. More than anything I have been growing for three years now, in small environments. Those plants you see are negligible, one of them isnt even mine. The other three were mistakes that I figured not to bother ditching. My last two grows were major successes. I already did knock the wall down between my closets. It was one single closet that was split into two. As far as the cmh goes, I'm totally on board for straight cmhs. Here's some pics of my last grow. Also I grow only high yielding autos. Stuff like; white widow, northern lights, pineapple express.

I use roots organics original soil with perlite amended in. Nutrients are all the organic line of Roots Organics dry. I use kelp meal, worm castings, domolite lime for cal mag, molasses in bloom.

One CMH should be enough for 4 plants in a 3x3 sq ft set up, I'd stick with just the one light unless you plan on adding more plants.

I have absolutely no experience with autoflowers though, so I can't comment much on that. What I can say is that I'm not crazy about autos because you can't control their veg growth. Consider getting some regular or even feminized seeds next time around so that you can veg the plants to 1-1.5ft tall and you'll get the harvest you're looking for! If you're looking for yields, I'd recommend Dinafems Critical + 2.0 strain. I got it as a freebie and treated it like absolute crap, was almost always droopy and underwatered and didn't get as much nutrients or love as it should have and it still yielded nearly a QP in a 2g pot. The quality of it was pretty impressive too.

Your plants look good and it sounds like you have a pretty good grasp on things, however I think the autoflower strains are what is holding you back from getting the yields you want.

Very good observation man. I have roughly 30 feminized pheno seeds that should be high yielding. I have been contemplating switching.

Yeah you can hit a lb in there with two 315s I almost always hit 8 oz even on a bad run off a 315 in 9 sq ft. You have almost double that for sq ft so with two and a decent run a lb should be easy. I have never done well with autos but some people do and I gave up quick as I already know how to do well with photo period plants. I prefer running clones over anything else as they are the same every time which makes it easier to dial in and get better weight. I have noticed though that my mothers that I selected under cmh do better than popular circulated cuts, I think this has to do with the fact most were selected under hps. Death Star for instance was B+ grade quality where as I have less popular strains like critical kush that I selected under cmh that is hands down A+ quality.

It sounds like everyone is voting in two cmhs. I'm with it, I really enjoy the quality of light and the overall effeciency. 8ozs under one light sounds very dobale for sure. I will consider investing into another cmh. I really enjoy my nanolux. I do know phenos produce very highly. Autos can be very tricky to learn honestly. They cant be over fertilized, trasnpalanted, they have very unique cycle. If dialed in and good genetics you can produce large yields in less than 3 months. My setup is light tight, that being said, switching would not be really hard. I'm kind of thinking that I could do autos in winter and phenos in summer. The 12/12 hours would allow more lights out and less cooling. In the winter I could take advantage of extended lights on hours for autos.[heating]
