First off wow! I love your designs man...it made my night to stumble across this. Amazing engineering skills man...I'm just gonna throw all my thoughts out here since you want to hear what ppl are thinking
I'm all about making things easy to clean and fix or modify later..so I kinda lean that way in advice
here's a few thoughts...first you talk about keeping the containers secure..I think it seems like alot of work to try to make all those square holes...I see you said they're easy to make but how easy to clean? Are the side supports necessary? I mean I'd just go with a front "bar" that holds the rows in place. I assume you have a bunch of the tree pots and you could just stick one in between as a placeholder if there's an empty spot so that the plant doesn't fall sideways. This way you also have the flexibility of removing the bar/lightshield for cleaning and stuff and you could also slide an entire row
down a slot if ya know what I mean. I do a long plank of wood that just slots into place so you can pull it out easily later for cleaning.
..another thought I had was metal walls and magnets on the back side of the pots...no shelves..just flat metal walls...nice and open and you could "stick" plants anywhere you want. That's kinda a completely different design though.
...another thought I had was just fastening clips behind each treepot and cliping it to the back of the pot.....again I'm all about the easy cleaning and open environment for good airflow.
That 's a ton of plants..I strongly recommend something automated...like maybe a mini flood and drain or nft. I think blumats would be more work then they'd be worth with that many plants man. They're awesome but dialing in that many of them and the price of getting that many...I think you'd be better off with just timered watering or regular drippers. Gutters are also a good idea..they seem about the perfect size..waterproof..angle pieces..downspouts..etc..
On the lighting, I like the first placement.(sorry!)..squared with the side walls, also I'd hang the bulbs tip down and cover the floor with plants as well. If you don't cover the floor with plants for some reason then I'd switch the bulbs to tips up..ah, nm I didn't see #'s were so high, so mount them tips up so the light reflects off the ceiling instead of the floor. I also agree with justwatchin on the cmh, I've used them for over a year and they're a good bulb and great for veg but I personally found the buds to be slightly smaller and leafier....I recommend at least running a cheapo hps on one side (on the first run) and check it out for yourself...the opposing far walls will show you the difference in bud structure. If you were running 3 bulbs in there I'd say make the middle one cmh..but with just 2 I'd go with hps's...cheapo hps too, nothing fancy....just cycle em out when necessary. I think my cmh buds were slightly more frosty but also way leafier which is gonna get trimmed off anyways
hard to fully explain but overall I feel I get more quality with hps..ie, bigger calyxes and less leaves.
hmmm..I'd put doors on both sides, or if it just opening from the front attach some of the racks directly to the doors....that would be really cool...like refrigerator door style. Whatever you decide to do for doors, or if you leave room to walk around it...make it easy access
...I really like the dome idea too.
Might want to do something with a cool tube in such a tight area...or at least leave an option open to install one later if necessary.
Man...now that I'm looking over the pics again...this thing looks like it's about the size of a bed...or would fit under
...might be jacked up a little...but you could put some fake drawers on the side...oh wait new, bigger house...but still
been working on my bed idea for years...hmmm..
