Hello all...been a while!
I haven't been around for a while, havent been farming as much at all lately myself...
But a friend of mine is starting a little grow and asked me for help...I figured why not reference hooka since you guys helped a load in the past..My friend has a medical license, btw.
She wants to build a cabinet out of wood to fit a specific spot in her home. The footprint she has to work with is roughly 3x3 and she has about 7' of height available...I drew up a rough plan and ran into a few questions, hope you guys can help out
I figure, she should make the most out of the space she has, and since she has 7'+ of height, she should make a double decker cabinet. Since she wants to use wood, i figure make a 3x3x7 frame using 2x4s and 1/4" plywood sheets on top of the frame. She already has a seperate seedling/veg room so this will be a flower cab only....So I wanna split the cabinet at the halfway mark, and have 2flowering cabs each 3'x3'x3.5' and i wanna see if we can fit a 400w HPS in each level, using mylar on the walls and the ceilings flat white. The lights will have to be air cooled of course, i assume.
The plan is to keep 2 plants on each level and keep them short with a lot of LST. I would consider myself pretty skilled with LST, I once grew a plant in a similar sized box which utilized ScROG and the plant was about 10" from soil to mature bud tops...and I got a decent harvest, considering the amount of heat stress suffered using 450w of uncooled HPS (i got about 6 ozdry)....I want her to achieve similar results for each of the 2 levels. My hopes are that if we can cool the lights efficiently, she should get around 8 oz from each level each harvest. I will be suggesting indica dominant strains...or sativas with short veg under scrog..
My questions mostly concern venting and cooling. How hot will a 400w get in that small of a space? I assume pretty hot...I plan on having 1 or 2 4" fans moving air around in each level, and a vent or 2 on the cab divider, with a 4" inline fan pulling air through both cabs and out of the top of the cabinet. Does she need a larger inline fan? How many CFM would be sufficient for spaces that small? I was also thinking......to help deodorize/ sanitize/ and move air around more...Maybe she could put one of those home air purifiers in each level as well...They are about 2' tall, and the fan speed can be adjusted...some also have optional ionizers or ozonators. Would this be a decent idea? She isnt concerned much about noise, she cares more about odor and heat. She works and doesnt want to come home to a burned plant, or a burned home...obviously.
Sooooo if anyone with experience, or some old heads wanna chime in...feel free. thanks
