Hey folks! Time to get my new gardens planned and built, which is giving me a hell of a time. So I really appreciate inputs, ideas, and admonitions too nods @DonBrennon & @TheStickMan (yeah it's still not built lol) Basically, it's a 2-part setup: a veg shelf and a grow room. I tend heavily towards no-till and big bushes at the moment hehe whereby I also want to get into growing regulars in the course of this year, which will have to involve smaller containers and recycled soils if I get that right... so I need a main grow space that is flexible and can do veg and flower side-by-side just as well as a big long-ass reg-veg with an auto or two in it, where I can scrog or LST or go vertical, whatever, in the next few years. The cannabis is only a part of the total system, and will have to share spaces with my veggies here and there- especially the nursery area. (Probably more a question of time stacking: not to have males during the main vegie-propagation times) The growroom: For starts, I'm going to be using the equipment I have, whereby I plan on going all LED (thinking around 4-500W total) and perhaps getting an S&P soundproofed vent... though actually I need much less airflow -- even in the new space just 60m³/h - and that's calculated with a complete turnaround of the air volume every 5 mins, plus added 30% to take carbon filter resistance into account... But I digress, the hardware: Lights: LED: 200W of Cree COBs 3500K HID: 150W MH & HPS CFL: 1x 200W each of 2700K & 6500K Ventilation: max. 800m³/hr Ventilator with carbon filter, regulated via 5-step transformer oh and that lil 15cm fan for air movement, probably will want supplementation... can have a max floor space of 1 x 1,60m (= 3.3 x 5.25 ft) with a room height of 2,4m(= 7.88 ft) so that's an area of1.6m² = 17sqft and a room volume of 3,84m³ = 135 cuft So enough space for 2 gals in big pots, 4 in 28L, or more in 12L. I'm hesitant to go any smaller than that.. though my protoplasma water feedings may be just perfect for keeping those smaller containers supplied... main thing is: I want em wavy and happy, not squished and cramped as they were in my closet! needs to be as soundproof as is reasonably affordable, since it'll be in my bedroom Alot of that is going to be in the wall buildup, whereby I am thinking of insulating the fan itself too. At the mo, I'm thinking a double-layer drywall on the outside to absorb the low frequencies, and something rougher between the frame posts for the high ones & for storing humidity? I'd like the walls to be as narrow as possible whilst fulfilling aaaaallll my wishes haha also has to function as a humidifier for my apartment. I've moved to a new-fangled passive energy house, and they're blowing the perheated air into my apartment at 20% humidity (don't argue. Don't even comment. I can have screaming fits about this all day and would like to spare you that LOL). Because, things over people and all that. So instead of BUYING a humidifier and WASTING electricity to correct their health-damaging system at my own cost (the official recommendation), I shall build an organic humidifier that uses a bit more energy but gives all sorts of lovely byproducts. So I will be funneling one of the apartment's intake spots into the room - it's been at a pretty constant 20°C (68°F) and 20% humidity all winter, though I have yet to see what will happen in the summertime. As to amounts, the "normal" setting for the apartment makes for a turnaround of 1/3 of the apartment volume/hr, I let it run at "minumum" most of the time, which has to be less, but noo idea how much that is. So I do need a second intake, which will be from the bedroom. I was a bit scared I would overload the system fan(s) by ducting the air from the intake hole (10cm diameter) near the ceiling to the growroom floor where I want it, but have since tested that with a piece of 20cm ducting - and I doubt it will create problems. To give you a better idea, here's the corner the space will be built into: (some of you may recognize parts of my old closet haha) and the ducting 10->20: The nursery is part of my general gardening area that includes my wormbin, resource collection, perennial edibles garden, and soilfying experiments -- aaand also needs to house all my div. handcrafting stuff, my microscope, and have a biiig workspace for painting, potting, and everything! All on 4m² LMAO Just so it's clear why the nursery is already at max size It's basically just a convertible shelf/mini-closet for sprouts, clones, sexing... and males. dimensions: as a shelf with storage space under: 1m wide x 55cm, just shy of 60cm high, as depicted I'm figuring I can do the cloning+sexing in there too... as a minigrowspace it'll be max 1m high, and yeah I'll have to give some attention to actually sealing it off. Lights: for now, I'm using my old bentup seedling lights (55W, adding the 2nd bulb gives me 110W in there, I can raise it so it only takes 10cm height off the total), looking to go LED here too... some bridgelux strips over at cutter caught my eye a while back... Same goes for the perennial herb & tomato garden that'll sit atop of the space similarly to how it is now.nThat 50W COB lights up half the apartment and is a total waste of electric Ventilation: I was thinking just a computer fan would do the job until I started thinking about flowering males. I wonder, do males smell as much as females? Will a DIY carbon filter do the job? But will the plants even fit in there? What pot size is the minimum for a good healthy male plant? I could of course let them bloom out on my balcony, but in summertime there won't be any sun there, plus knowing me, all doors will be open all the time and the pollen will be in the air and get into the growroom... agh! lol Does this look like it could work?!? Especially the nursery seems iffey to my mind, probably not lastly because I haven't done regulars at all yet And any ideas on a slender but effective wall buildup for the growroom? Cheers!
