Need some help

[kips0n]

Hi everyone i want to buy my own growset but i need to know one thing:

200W CFL witch 60x60x140 dark street is good for 4 plants?

 

[medicalmj]

You need to be much more specific.

ok soo i would like buy a grow tent DS60 in pack which included:
tent DS60 2.5 60x60x150
HPS-150W with bulb NATRIUM WLS-150W 15000LM
CARBON FILTER CAN2600-150m3/h fi 125
FAN DUCT FI 125 150m3/h
+ other small things like termo/higrometer

all stuff you can see here

 

[typrastaman]

and some nutriens...

Hi! I think you could also try with 200-250W and get more prodeuction. With that extraction you'll be fine

 

[typrastaman]

best is 2 plants only, just top them and low stress train them and they will get big

What up...look into pll bulbs 55 watt, you will be better of building your own cab
Go into the micro section and look for pll club alot of good info. For 4 plants and heat its a good way to go.

so i decided that i buy 250W HPS
and want to make wooden box 60x60x minimum 140

you have right my friends that this fan is a little bit weak

So the US hasn't went metric so I had to convert to feet, which comes to about 2' x 2' x 4.5'. With the reflective walls and a 250 watt HPS that seems like a lot of wattage for 60cm^2 (62 watts/ft^2 plus the added efficiency of the reflected light). Just going a little more in either direction will yield more and still have plenty of light intensity. Perhaps something like 60 x 90 and add some head room too. So why not consider 60x90x(200-240), which equates to about 2'x3'x(7'-8') for us Yankees. Still the size of a cabinet for stealth yet much roomier.

Not sure about the fan specs but a 4" (10 cm) inline fan would be well suited. It should be rated at least 120 CFM or at least 3.5 Cubic Meters per Minute (CMM). And you can get a speedster fan speed controller for about $25USD to turn it down if needed.

As far as how many plants it will be well suited for is a matter of personal choice. But I'd say 1 if there the size I grow em, or up to say 24 in a packed sea of green. So 4 would seem a good number...

Thanks for your replay dude!
I cant make bigger box coz i dont have space for it maybe 60x80
is possible but high is max 160/170

inline fan 100mm fi? i think that exhaust fan is more important so
for intake fresh air i want to make few small or one big passive
hole. Of course i want to buy speed controller too. what do u think about it now?

and again thanks for exhaustive answer

 

[medicalmj]

If 100 mm is 10 cm then that should be a good size fan. I assume it will be be rated around 3.5 cubic meters per minute since all good inline fans of that size are around that range. As far as height, it'll work just keep em short.

Stick to the HPS you'll get more yield from it. As for your fan, in a small grow space its a little bit harder to control the climate so I suggest you to take a fan with a higher cap, especially if you're using a HPS bulb. I would take a fan of 500m3 for a 250watt HPS bulb, you'll probably are going to run it on 60-70% but if it gets too hot you always get go higher. Thats why you'll always need to take a bigger fan so you wont have heat problems during the summer.

You need the dimmer/speed controller, else the fan will always run on 100% we dont want that.

If you get your Secret Jardin tent you need to check it immediately, their quality has become so bad. Check the zippers and see if there comes no light trough it. Mine was totally fucked up.

If you can and have the materials to build a growbox I would do that. If you're going to use a passive outtake the outtake should be 3 * the diameter of the intake.

thanks for your replay, so i want to build a box,
i make it from wooden plate, i will have 1 exhaust fan with carbon filter and passive and fan to intake air

That small fan is for moving air along ducts, not for pulling air through a carbon filter. For that you need a UFO-shaped fan or squirrel cage fan (i.e. centrifugal and quite powerful)

y i know so i want install that fan

all together (of course at the bottom intake fan + maybe 2 small passive)

Totally agree with this guy, squirrel cage fan aka softbox aka snail fan in a box are the best fans you can use. They dont produce a lot of noise, they are very low noise compared to those UFO shaped fans (aka inline filters). Here they're very populair and almost every grower uses them.

A lot of growshops offer complete sets but in most cases they misconfigurate the fan and filter. They do it so you'll come back and buy even more stuff from them.

Alwats use a bigger fan you don't have to run it on 100% so there will be less noise and it will be easier to control the climate in the summer.

I have had one fan like kips0n has mentioned in his previous post, it 's a shit fan don't use it. If you run it on the full speed it creates a lot of noise and it didn't do any good.

i dont have money for this soo if u had this fan and u told that it sucks maybe UFO like this will be better

or CAN-FAN fi100 but i dont know what noise they making

 

[FromHolland]

These kind of fans are called inline fans, they're always noisy when they run on 100%. Thats why I said you need a bigger capacity fan, if you do then you don't have to run it on 100% so there is less noise.

You can put an inline fan in a box, you need to put sound isolation pads in the box, drill two holes in the top lid, attach the fan to it, create two holes (according to the diameter), use isolated tubes for the internal connection. It will decrease the sound a lot.

ok so i decided to buy CAN-FAN 190m3/h fi100 and now i have to choose filter..
can i buy CAN LITE 300m3/h fi100/125mm ??
if you can plz replay fast coz i want buy today

 

[typrastaman]
