Flip Flop Sealed Room HELP

[iSmokeTrees]

So I'm designing a flip flop sealed room grow setup as I'm becoming a medical caregiver. I plan on having two flowering rooms at about 10x10 each, both having two 4x8 ebb and flow trays with three 600w HPS lights above each tray. So 6 ballasts, 12 hoods and lamps. I have been listing out everything I need right now and designing it while I look for a location I like to put it in at.

So my question is: does anyone have a link to a similar design? I'd like to look at what other people are doing because I'd have a lot easier and more successful time reverse engineering my design by standing on the shoulders of giants.

Also: Is it possible to flip flop a water reservoir between two trays in each room? As in have one 100G reservoir that alternates which 75G tray it feeds? Or is this just a bad idea and I should get two separate 75G reservoirs, one for each tray?

Thanks for everyone's help and input.

Hi iST,
Quite the project you're undertaking. I don't have any experience with flip-flop mechanical stuff but I've used one res with two Ebb & Flow trays.

All you need to do is to slightly stagger the flood times so that you don't suck your res dry. You may want to have separate reservoirs though in case you need to alter nute regimens. Like...say you have a nute hungry strain on one tray and a normal or light feeding strain in the other tray.

Also separating the trays isolates each from the other in case of disease.

If you do share a res...you'll have to change it more often because nutrient salts and such will build up faster. Good luck,

Check out my thread. I am running 3 600's over 4x8 trays. IMO its not working and I am thinking of changing to 2 1000's per table.


The easiest way to deal with the tanks is to use two pumps on seperate timers. Make sure you leave enough time in between waterings to allow the table to drain and fill the rez back up. You could build a manifold with valves/solenoids etc but for two tables, I think two pumps is easier and probably cheaper.


You may want to consider your strain needs. If running different strains, you will want seperate reses

Thanks guys I appreciate the input. I'm really looking for designs/diagrams/etc. I'm not sure how I go about determining how many and where I need vents, etc. I've been growing in my tent, unsealed, and the sealed room is a step I wanna take but I don't want to make it broken and have to spend more time and money in fixing it.

Again, thank you for all input!

You'd probably be better off with two 1,000's above each tray instead of three 600's. The 600's don't do a very good job of lighting up a 4' wide area.

You can check out my 9600 watt grow.. I sealed it up later, but its pictured as unsealed. I can try and find my drawings I had for it. but the air cooled hoods always vented into my attic, and when I sealed it, drew air from the hallway. I had a portable dual hose AC in each room. I had to manually move my CAP 3 ppm monitor to each room every flip cycle though because I ran out of money for a second one LOL.. I had two tanks though so it wasn't bad.. I vented new air through the room for the night cycles too.

I kind of agree with what PharmaCan says about the 2X 1000's.. I had "dark" spots at some corners. The best would be if I could have put them on movers so they moved in their respective rows.. But I still got a good yield. Its just something that could have been improved on.
