Is this a decent design to follow on grow room 2?

Drew this up today, basically the first schematic of grow room number two.

The room would be 5 feet wide and 5 feet deep, height is variable but likely around 6 foot tall.

I would have 16 plants in 8 pots (2 plants per pot). Each pot is 2 feet wide, 1 foot deep and 1 foot tall. Mainly using this setup because I already have these pots, and they will perfectly fill a 4 foot by 4 foot grow area. On the right of the image below you can see a vertical view of where the stems of the clones would be.

In my drawing I gave each plant 1 cubic foot of space to grow in below the screen, is that a viable amount of space?

I want to use a screen growing technique for maximum light penetration. A 400 watt air cooled HPS (with a 250 CFM inline) will sit above the plants, and 4 separate 2 bulb 4 foot flouros will sit sideways on each wall of the room, facing the sides of the screen within 4 inches of the plants. See the picture if that doesn't make sense, two of them are drawn. I already have these lights from my current grow, so I figure why not add some lumens. This would equate to 400 HPS watts, and 320 flouro watts.

This will be inside a shed, with air being forced into the grow space on the bottom with a simple house fan, and air being drawn out with an alleged 2000 CFM box fan, although I estimate it actually only pulls about 500 CFM with the carbon scrubber I put on it.

With the air cooled HPS and the box fan in conjunction with forced intake, is this enough ventilation for this room?



My first grow is going much better than expected, you can check it out here

Basically now I have proof of concept, I want to make a higher quality permanent grow space. If you see any flaws with my design or could offer any suggestions, I would love to hear them. Feel free to mock my design if it is constructive.

Thanks, and plus rep for any assistance of course.

Peace

you need to change your plans about planting two plants per container. You can only grow one plant per containter. Two plants will get their roots all tangeled and choke each other out.

I can swap to 1x1x1 pots instead, I just prefer not to because I already have a bunch of the 2x1x1 pots.

The way I drew it up each plant gets over 5 gallons to itself, will they still get tangled? I thought the general rule was minimum a gallon a foot, but these guys will only be 1.5 - 2 feet max.

u could put some cut to size plastic inbetween the 2 plants, roots will sperd alot if not blocked

when your grow at the moment ends look at roots

your roots will be fine...... as long as you dont have any desieses or problems from one plant it will instantly spread to the other one it shares with 2x1x1 is alot of room or root

After reading about it I decided it's probably worth it to just get individual pots, it shouldn't be too expensive. Thanks for the input.

Unless the pieces used to partition off a larger pot into different growing spaces were sealed there would eventually be some intermingling of roots unless the overall pot size was so massive that roots never grew to far enough to reach the partition.

If there is a crack or a hole or some uneven area, roots will eventually find it and make their way through if there is any sort of growing medium there the plant can survive in.

Plants are normally jammed tight enough together that if one develops some certain problem it can spread to another so by sharing soil you just increase the chances that any below soil problems will spread and effect plants that otherwise would not be effected.

It is never a good idea to grow multiple plants in one container unless it is under very unique conditions, like very massive containers, or if for some reason it is the only way someone will be able to grow.
