Hello.

I really got tired of this unfair dealers here. So I just wanted to make a small growbox for myself.
I'm thinking about autoflower plants, because they stay smaller. I was checking on forums and found a lot of ideas.
But I still have a lot of questions and every answer would be helpfull.

I was thinking about the size of my growbox. is a growbox 60cm x 60cm x 90cm big enough for 4 autoflowers?
or should I make it 60x60x120?

my next question is, what light would you recomend? is a 150W CFL light enough for 4 autoflowers?

are 2 fans with 105 m3/h enought? (one for intake one for outlet)

should I use mylar? or is it true that mylar is not good for a plant because hot spots can create?

Thank you for your help! :)
And sorry if my english is not perfect :c

More height never hurts, but plenty of people grow in less than 3ft.

More light is always good, usually people aim for 5000-7000 lumens per square foot.

With fans, usually you want to run negative pressure inside your cab to keep the smell contained, also keep in mind your fans need a decent amount of static pressure to overcome the filter. If you have a single filtered out-vent and an un-filtered in-vent you will have positive pressure which is bad.

Mylar is fine, panda plastic is fine, white paint is fine. People avoid aluminum foil because it creates hotspots due to easy wrinkling, as long as you keep your mylar smooth you should be fine.

get a 150 watt HPS if your going low watt, you will get much better bud from a small HPS, or get a small Led panel, I would paint the inside white, and call it good, dont use an intake fan, only exhaust, and like orange said, negative pressure, then you can run your exhaust thru a carbon filter , and have no funny smell, you can build the filter yourself, you can order a small HPS from amazon or ebay, and get a small 4" inline fan like a can fan , computer fans are very weak with a 4" fan you can use a speed controller to slow it down, then you dont even hear it running, an LED ufo will out grow the cfl bulb, I know people who grow with cfl, and get bud, but they tend to want more and more cfl, then the heat builds up, and you have twice the money in cfl than you would a HPS bulb, if you just start with a hps in the first place

i grow in a small chamber, just 1 plant at a time
you can make things easier by training plants to fit the chamber
LST is good, SCROG is another that can be used

Depending on his budget I would almost say go with a 250 watt hps, which would be about 7000lumens/sqft in a 4 square foot space. I feel like he's looking for a simple around-the-house item grow though, so I'm not sure how over his head all of this is. :D

I also would say fuck autoflowers, just get 1 good feminized plant and run a small mother chamber and pull infinite cuttings from that. Would probably save quite a bit of money that could be spent in more important areas like lighting or ventilation. Maybe this is what could be done with the extra foot of height, a 2x2x1ft mother/clone chamber to prep a 2x2x3 SOG chamber. But again, probably over heads.

i have always been facinated with perpetual growers, its a real green thumb , taking care of mulitple plants in multiple stages of life/ grow cycle, but wow , the constant supply, no need for outsiders, no need to buy seeds or get clones from other people,
I am with you all the way on the brighter light, get the biggest one you can, as long as you can control the heat, i use LED myself, I just thought the idea of HPS was allot cheaper and easier for him to hook up, but if he is "around the house" type of grower, they are always super impressive when they grow some good bud

Like already said.
Get these pieces of equipment first.
4" inline fan with small carbon filter.
150-250 hps light or led panel.

Build around those and you'll be excited. Don't use computer fans for a flower chamber. Only for small veg area.

wow thanks for all the answers.
well I like to see good buds and maybe a few less. than have a lot of buds and low quality.
I was asking at our local grow shop. and I just dicided I'm going for a 80x80x180 grow box with 250w.
led panel is way to expensive for me. so I'll use a HPS light. I thought CFL is good for autoflower because I've read it on internet. but he sad HPS is way better.
I'm going to use a big strong fan for outlet and a weaker one for intake.
and I'll be using mylar :)

You won't need an intake fan. Just make sure you have a good strong exhaust/extraction fan. I use a 6" and only keep a filter where my intake vent is for clean air. Then I added a air purifier that scrubs the fresh air coming in.

The exhaust fan pulls through the big carbon filter and then through the air cooled hood and out the room. This will save money on the intake fan. Under certain situations you might need the intake fan but most won't unless they have a sealed room.
