curious as to why your getting 3 x 150w HPS's in there... that's 450w total, why not just get 1 x 400w HPS in a cool tube, save space and money a 400w in a cool tube with an inline fan will probs cost you around £180 roughly $200 or so (my conversion is wack), that's what I'm doing and by the looks of it my cab is roughly the same size as yours check it out in my sig. I'm confident that I can control temps in it and I'm going to do ScrOG.
ok im checking it out now!

Actually looking at it your space is way bigger than mine XD

My recommendation would be to go with the 400w HPS in a cool tube and mount it along the depth so that the extraction is out the back and do a dished ScrOG... I don't know how better to describe how to put the light, something like this:

ignore the dashes XD
yeah see mine 5 1/2 feet long or something like 200cm long somewhere in that range. each 150watt i want to get is only 35cm long so i figure 3 in there would evenly distribute the light. and also i like your setup very nice.

EDIT: Haven't got it yet but its 50cm long according to the measurements and if you have 60cm deep that'll be fine you got 10cm for airflow which is a fair amount.

thanks, did you see what I meant about how to position the light and the dished scrog idea from my previous grow?

I'll stick to my opinion of you'll save yourself money and hassle in the future if you just get the one light, just think, 3 ballasts, 3 lights and 3 cool tubes plus all the ducting you'll need to do, replacing bulbs will probably start to get expensive too (or at least more expensive than replacing 1 x 400w)... what a mission :)

Good luck anyway, whatever you decide!

Stay frosty.

Maybe a bit late to the party but i would build a small aquarium base around the bottom of it to lift it up 12-16inches. Cut holes big enough for your pots to fit in so they are level with the floor. Youll gain some height and keep your roots below. LST and train everything to the floor using eye hooks and zipties or even a small SCROG, the added height from having your pots sunken in gives you a lot more options for the future. You could go a hyrdo route or keep soil, having the pots below also keeps your water temps lower. I dont know how your floor is put in but if you knocked it all out right now and place a small lip around it so you can put 3 ply wood sheet in and have them rest on the lip you could always change up the size of your pots/style and have something that you can do a lot more with. With a little bit of work you could fix a lot of the problems people have pointed out.

Personally i would build the extra bottom to sink your pots in and it acts as a nice place to store your nutes/whatnot. Get a few T5 sets and go with the better T5 aqua lights https://www.rollitup.org/indoor-growing/358190-led-without-leds-my-first.html. Add a UVB light for a few hours near the end for that little bit extra. If you really want a HID in there then throw a 150-400 in the middle (A 400 with a cooltube is possible i think) and keep the T5s on the sides.
