This is my first indoor grow and first thread. Though I’ve grown outdoor for many years, I’ve found moving indoor to be a very different and complex. I’ve returned again and again to ICMag for information, ideas, and help, so I’d like add my thanks here.
Thanks to ICMag and its members for your journals, discussions, and debates. Your shared experience and knowledge has given me the confidence and valuable information needed to plan this setup. Contributors, your posts have helped plan every aspect of my room. Thank you so much!!!
Seems a stadium grow best fits the narrow attic space I have to grow in. Tell me your ideas if your experience points to better use of the space. I plan to build a sealed room within the attic space. I could use some help to finalize my room length and number of lights.
Northern Farmer (NFR) mentioned increasing his room size and veg time because he felt pressured to grow fewer plants by changing laws. Local law has me in a similar situation, so I’m considering the effects of setup on veg times, cost, and yield.
I could use your help choosing a room setup.
Here are the conditions.
24’ long x 21.5’ width attic space
Maximum 18’ long grow room to be built within the attic
6.5’ to 7’ maximum grow room width due to height restrictions
7.5’ height at peak, 5.75’ height 3.5’ from center
5 to 7 - 1K vertical bare bulbs, sealed, mini-split, dehuey, CO2
Stadium, 3 shelves per side, 10” wide drained shelves with 14” rise
Soil with drip system in 2 or 3 gallon pots - 8” width pots
16 plants per shelf for a total of 96 plants
99 plant maximum, local legal setup
Room will be used to veg and flower
5 – 1K lights with 22” between lights, 20” from ends (thanks to NFR)
10.6’ long room
96 - 8” wide pots fill 6 shelves with no space between pots
67 watts per sq ft assuming 7’ width
6 – 1K lights with same spacing as above
12.5’ long room
96 - 8” wide pots fill 6 shelves with 1.5” spacing between pots
68 watts per sq ft
7 – 1K lights with same spacing as above
14.3’ long room
96 - 8” wide pots fill 6 shelves with 2.75” spacing between pots
70 watts per sq ft
My first thought is to choose the smallest room and minimize cost with shorter veg times and lower yields, but I’d like to hear your opinion and advice.
Is it cost effective to run extra lights, CO2, and AC in exchange for extra space between plants, longer veg time, and increased yield? Which setup do you think is the most cost effective?
How much difference do a couple inches between pots make?
With your choice of setups, how long do you suggest I should veg, using a strain that finishes in 8 weeks?
Should I use 2 or 3 gallon pots for the veg time you suggest?
Other ideas for an attic setup that will more efficiently use the space?
Thanks for your input
