Hi Everyone
I finally managed to put my list together and i was wondering about asking you for advice on did i matched all parameters of fans, light wattage, size of hoods etc .I don't want to mess anything up since it will be quite of a step up from my previous single tent 4x8x7.5 with two 600w and one 400w.

My space is a pretty wet basement about 75-rh and 59f unheated (central gas heating available).

Veg tent:
4x8x7.5
1x600w MH
Adjust a wing or closed sides barn reflector
5" wooden box fan 550m3 + variac controller with temperature sensor
5" rhino pro 500m3
2x 20w oscillating fan

Flower tent:
5x10x7.5
2x 1000w Philips son-t in magnum xxxl aircooled with 6" in line fan with controller 595 cmh
6" wooden box fan 1500m3 with sms 8amp controller with probe
Mountain air 200mm 1610m3 carbon filter
3x oscillating fan

70pint dehumidifier ( thanks for advice guys)

I am thinking of growing 8 or 10 plants , not sure yet. Previously i done 8 plants in tent that now will be veg/future clones station.
Veg topping from famous LBH tutorial (forever thank you for this method)Flower tent will be scroged. Plant this time is shining silver haze. After last crop of barneys farm glookies got soo many male flowers and bananas and got seeded i thought i reach out for classic. In future planing to choose mother from resular seeds.
Basement shaped like on the uploded drawing of mine.

I really would appreciate if you could correct me if you spot someone that don't match or something else that would be more beneficial or anything else.

P.S English is not my native language

A single 600w mh in a 4x8 is going to make for some lanky plants.

Why is the humidity in the basement so high?
Click to expand...
Uk is pretty humid as it is and this basement got some sort of pump in floor in case of flood since people next door had flooding. Pump is covered with something ninja turtles could come out off
 
When you get to flowering, 75% humidity will be a recipe for mold. You will need to make sure whatever source of humidity gain is stopped with a vapor barrier, such as heavy mil plastic or basement paint for waterproofing
the vapor barrier will make it so you aren't battling humidity gain.

Next you will need a dehumidifier. The less waterproofing/ vapor barrier you do, the more dehumidification your basement will require. Also, if the basement is taking in a lot of air, and it is 75% humidity outdoors, then there will be no point in trying to dehumidify that air because it will exchange too fast.

During flowering you will want around 60% RH or less. Veg stage 75% will be OK.

You need to be able to control your grow environment to have all the investment be worth it. You also dont want mold/mildew on your buds, it will be trash.

Hope this helps! If you have more info I'm happy to help

30L is a pretty big boy, should handle it. Might need a second one but I doubt it.
