4 Citizen CLU048-1818 3000K
On an HLG-320C-1400A
8 Ideal 50-2204CT Chiplok cob holders
All 8 are bare, (no reflector)
6+ ft l, 31 in w, 7 ft tall grow closet
Lights are 4 ft long, cobs spaced apart evenly
2 seperate bars, 1 holding the 4000k
Other holding the 3000k, side by side 8 in of gap.
I used two different heatsink types, first light consits of 4 mechatronix 120mm×80mm Passive pin fin style heatsinks, second build consists of 4 mechatronix ICELED Ultra 99mm×75mm Active heatsinks. The passive ones, i attached some 80mm cpu fans I had laying around on top for some added cooling power. So i had a previous post in which a fellow riu'er had figured the light numbers out for me. These are not my figures, but rather numbers put into the calculator for me as it wouldnt work on my phone. And these figures are only for one single light bar with 4 cobs.

Total for the 2 builds, came out to $620. Thats for parts ordered, materials for the frame, miscellaneous parts like the mounting screws that they didnt send with the heatsinks, and some thermal grease i had to source because i forgot TIM on the first order. I got everything for the frames from Home Depot. All the lighting components were from an online distributor.
I want to run 8-12 decently sized plants under these light bars. The cobs are spaced apart about 8 in (length wise) per frame. And about 8 in (width wise) per frame. So i figure it has a decent spread. Decent enough to scrog a closet grow 31 in deep, +/-5 ft long, 7 ft tall.
I currently only have 3 plants under the lights since the other beans havent popped up yet. But i will be putting more in dirt within the next couple days. Maybe even run a few clones from a friend. Im weary of clones tho, you never know what you might bring into your grow room, from someone elses.
Anyway, back to the strains;
1 Tangerine Dream fem
1 Currant Kush fem (clone, my last grow)
1 Diesel Berry Auto (may be dead seed)
1 Cherry Bomb Auto (in water, absorbing)
1 Arjans Haze 1 fem (in water, absorbing)
1 Freezeberry Auto (not a true auto, weak genetics, f1 hybrid, in water, absorbing)
They are all in homemade pots. Totes i drilled drainage holes into. I may end up getting some 10 gal air pots or something later down the road. But this grow, theyre in roughly 7 gal tote pots. Theyve shown good results as far as root development in previous grows for me. So if it isnt broke, dont fix it, right? Roots Organics 707 soil mix with some extra perlite. Fox Farms "Smart Naturals" with the dry solubles nutrient lineup. But i stray from their feeding schedule slightly, supplementing here and there, tweaking this and that to what i feel is appropriate and to get the maximum nutrient uptake as possible, compared to where the plant is at, developmentally.
I think I covered all bases as far as starting my new led closet grow journal. I'll start taking pics tomorrow or tuesday depending on how long it takes for the rest of the beans to actually sprout. Till then, heres a pic of just one light bar and a few plants under it.

I Run Any Where From 3500k-5000k and They All Have Advantages However My Favorite All A Round Is The 4000k.
