Hi,
I am:
Hungry for buds and been climbing to grower state of mind for more than decade (really) and seeing all your flowers messing up my mind.
Because I want my flowers were cured for few month already.
I have:
Love to cannabis
12 premium auto seeds, 2 bonus noname AK47 auto seeds
10 cree cxb3590 5000K 36V cobs
2 hlg-600-48A non-dimmable drivers with 12.5A (it's possible to add dimmer to cv driver)
14 10L h: 25 cm w: 22 cm grow bags
140L coconut substrate
0.5L grow, 0.5L bloom biobizz fertilizers
Water (harvested from snow)
Very cold house, wool felt and alluminium to make grow space
I don't have:
Neighbors
Heatsink
Termal pads or paste
Plans to sell cannabis since it's illegal here
This sittuation is extraordinary because, even though there is pretty premium setup, I'm not willing to spend a money to finish it properly. For now.
The reason is simple: it's going to be first and last grow in that place, since it's not mine house, I decided to move to another country as I sell land here next year, I learned that 24 lm301h quantum boards (24 qboards * 350 g = 8.4 kg + 2 drivers * 4 kg = 12.4 kg - quite portable) run at 25W-50W without heatsink is what I need with 300W-600W drivers (600W-1200W both) because of efficacy and because I saw prices and weight for heatsinks that able to cool cobs passively. I even tried to sell cobs and ordered 12 quantum boards abroad but canceled order because it was hard to justify waiting time and signal to customs about "growers choice" light board to myself, and there weren't purchaser for cobs.
So I decided to make simple cob setup for that grow with heatsink like on the photo (it's also possible to use it "bar style" instead of "board style" as it's detachable).
Hlg driver version is 48A and according to datasheet can work at 24V-48V with constant current 12.5A, so it, if I understood it correctly, can be driven with one driver at 45W * 10 = 450W or with two drivers at 90W * 10 = 900W.
Yeah, I am all about efficiency but as I said I am hungry for buds which is kindly blinding so I want to grow all 14 canopies at the same time with, possibly, 450W in 120 cm * 120 cm (4" * 4") grow space. I plan to harvest 2 * AK47 canopies earlier to make 4 * 3 raw grow space 120 cm * 90 cm (4" * 3") or maybe keep grow space size same adding space between 12 canopies and adding some cheap warm light or setting light fixture higher and connecting second driver running each cob at 90W, if I figure that heatsink can handle it in this cold house. I plan to run it 20 / 4 hours, having 4 hours during daytime, when house is warmer (12 p.m. - 4 p.m.).
Question:
Is it possible?
Thank you for reading.
P.S. I want to grow 14 canopies in one cycle because grow room is going to be inside my room this time, I will have few months to cure in snow in the forest and its not legal here afterall, so I want to play "hit and run".
