So I wanted to start a write up on a relatively cheap/easy set up for a home grower. This will be an open room for a cheaper build out.
Lighting is in your control you can get DE 1k HPS for 225-250 out hydro stores now so that’ll be your cheaper option. I’d recommend CMH for veg if possible at the least or if you can afford just in general - quality LEDs will do as well. I recently vegged with MH bulbs for the first time in a while and it really just doesn’t compare. It can be done but I’d recommend more plants under MH.
You can get away with just a drill here as you can have home depot cut your wood for tables. You can do 2x4x8s for 4x8 tables or 2x4x10s for 5x10 tables (go bigger if you have the space)
Supplies go as per table:
-6.5x- 2x4s
-Half a 4x4x8 for legs
-3 in screws for 2x4s
-4in screws for the legs
-4x 2 in 90lb caster wheels
-2 or 3x(depending on 4x8 / 5x10) 26 in x 8 ft galvanized corrugated metal panels
-Half a 10 ft gutter
Costs BEFORE lumber prices blew up was approx: $75 per table.
Going to leave 2 2x4s at full length and cut the rest in half(will post pics of tables later this evening) the 4x4x8 will be cut at lengths varying from 16 in to 8 in(depending how long your row of tables are) go down atleast 1 inch from each table end, do 2 unless you have like 10 tables lined up…
Other construction related supplies:
-30 lb. White Enamel Swag Hooks - 1 per light
-Light rope/hook hanger - 1 per
-18 in hurricane fan - 1 per table/2 lights
-6.5 ft width Scrog net
-Cable clips for wires.
No more than $50 per table on this part: approx: $125 total so far with 2 hps about $625 per 2 lighter not including exhaust/carbon filters. I have cooled up too 6 1k lights with a single 8 inch exhaust fan can do more in colder climates easily(so cal weather based.)
Since it’s an open room I recommend doubling up on filters. 1 inside hooked to the ceiling blowing air out a window(or your own made exhaust.) Have a cabinet/shed right outside the window and connect the fan blowing out to another carbon filter in the shed/cabinet(you can set up another filter in there to exhaust from that room if desired.) You will need a opening/window on the opposite side as a passive intake if you can cover with hepa filters without suspicion I’d do so.
Grow supplies/nutrients:
-Ph and PPM pen(cheap ones will likely break within a month-3 recommend spending 150-200 on good ones)
-Magnesium sulfate 50 lbs - $20
-Calcium nitrate 50 lbs - $40
-Any salt mix of 20-10-20 , 20-20-20. I use southern ags 20-10-20 nitrate special it will help with ph a lot if yours is high. Approx $55-65
Haifa MPK- 50lb 80 bucks(will last you several years)
45 gallon brute trash can for resevoir. $40
-light timer -$10
You can get myco/silica if desired but expensive and have still seen similar yields/quality w.o personally.
Besides the salt mix all these ingredients will last you over a year the Haifa will last forever(only used week 3-7 at very small doses). With quality Ph and PPM pen looking at 425ish total.
Oh yea ph up and down let’s make it a flat $450
I’d say 1 8in inline fan and 2 filters per 6 lighter(based on so cal weather) another $250 there.
$100 for a pump/hose combo to hand water
Another 20 for some totes to put under the gutters. You can get a $15 pump and hose line to pump out the run off or use that back(may as well ditch the totes and get a fitting to connect the pump directly to gutter.)
Almost forgot IPM get a Petra sprayer and 5 gallons of suff oil x - $225 total. Release 2000 lady bugs around Week 5 when you havnt sprayed for 2 weeks. They don’t do great with infestations but will handle almost anything that can come into your open room after you stop spraying Week 3 of flower. Catch it early or as a preventative it’ll do good.
So with a large supply of nutrients thatll last over a year with a 6 lighter. It will cost 625 per table with 2 lights. 250 to cool and filter the smell for up to 6 lights. And 725 in nutrients and such.
Room costs
$1600 for 2 lights
$2225 for 4
$2850 for 6
Either way you go you can profit first round pulling 1 lb a light. Although barely with 2 lights.
Ill post the gutters/tables/exhaust filter fans when I get to the spot by the end the day.
In terms of feeding as basic and generic as possible.
Early veg - 5-600ppm salt mix 1-150ppm calcium nitrate
50-75 mag sulfate
Late Veg - 700ppm salt mix 150-200 cal nit 75-100 mag sulfate
Week 1-3 flower. 900-950ppm salt mix 150-200 cal nit
100 mag
Week 4-8ish almost the same just dial back cal and salt mix 50-100ppm and add 150-250ppm MPK
Flush for 15 days.
Electrical can be chopped on a case by case basis. 4 light controllers about $100 about $200 for an 8 light controller as an additional cost not including the wiring/job.
Here’s some shots of my last harvest doing exactly this. 10 of cookie crosses from 6 lights.
