Sealed Room Design Help?!?!

New on the scene, also a member on another forum. Decided to come over here since the boards looked more active. Here are the details so far:

8' (Lenght) x 6' (Width) x 7' (Height)

1. New Electrical Panel (It is either a 40 or 60 amp)
2. Fibre Glass insulated walls, sheet rocked, insulated floor and insulated door (Air Seal Room)
3. White walls (will be applying relective material)

Trying to fit 50 pots with an Ebb Flow System.

My Questions:

1. I will be using the same space for vegetation and flowering, so could I use just one type of bulb for the different stages? Or could I have mixed bulbs throughout these stages? Or should I change the bulbs at the different stages?
2. I am thinking about running (3) Ventilated Lights and will be using insulated duct. If I am using that many lights in the space noted, will I need a booster for extra air flow in the ducts? And do you think I should go with (3) 600Watt OR (3) 1000 Watt Lights?
3. As far as carbon filters go, does it matter what size I get? I ask this because I plan to use a big one, probably a 4 footer if it exists....
4. Should I run 6'' ducts exclusively?

Respect!
Scoob...

If they were small pots, they'd fit I guess. But you're room has a 48 sq ft footprint. Which means your pots will have to be under one square foot at the widest part to fit 50 pots in there. I guess if you grew in 6" rockwool cubes you'd be alright. But your plants would be small. Also, remember your room for resevoir, etc.

1.) Toe-may-toe, Toe-mah-toe. Everyone kinda does their own thing here. Some people veg and flower with HPS. Rarely, some do it with MH. I think most (like me) veg with MH, and flower with HPS.
2.) Again, your choice here. I personally think bigger is better... but you're going for small plants. They may not need the 1000W lights. Would be nice. They'll like it. But it's more expensive for your electricity bill and again, you're not growing huge plants.
3.) Bigger is better again. But in this case, huge would be unnecessary. It'll just last way longer than a more practical size one would.
4.) Sure. As apposed to what other option, though?

Let's say I am looking to produce as much product as possible, how many plants would you recommend? Reason I said 50 was because I was suggested that on the other forum. I know more space= more growth. 40 sounds more reasonable?

1. I honestly believe I will use MH during vegetation and HPS during flowering. From what I have been reading, it sounds like the way to go. After answering the bottom questions, I have a few products I would like some feedback on.
2. So now, would you think I would get an excellent harvest from using (2) 1000W or (3) 600W or (2) 600W?
3. What size should do an excellent job in this work space?
4. Other option being 8''

just curious as to why not have separate veg and flower rooms? the efficiency and flexibility usually make it the preferred choice to grow.

Because I don't plan to harvest through out the year...

Any help with the questions though?

For the most amount of product, you want the biggest plants you can grow in your space available. Eight to twelve large plants aught to be enough to keep you busy and provide a very decent crop. With the right strain and technique, you could harvest about a pound per plant. I think that's plenty product. (and a goal to work towards)

2. Three 1kW ballast. I know that wasn't an option, but if you want big plants, you'd need good coverage and strong lights. Two 600s really isn't an option if you're going big. Cost of equipment AND electrical bill should drive your direction for which to choose. Three 600W is probably your best bet though.
3. If you're going big, then go big with your filter. You'll need to. The smell will be immense, depending on strain. I've seen filters as big as 5'.
4. Big plants, big air movement, big lights, big heat, big ventilation. Your filter may require 8" for proper operation. However six-hundred watt lights can be just fine with 6" tubing if the fan is strong enough. So it depends on your setup. Basically, the bigger your op is, the higher *potential* yield you can get.

Keep in mind, all this big equipment is going to take up space too. Think about it...
Carbon filter
Co2 cylinder
Walking space
Fans (but you can mount them on the wall)
Plants and resevoir

At this point I really have to step in and give you my personal opinion. This sounds to me like your first grow. I don't think it's a good idea to go as big as possible on your first grow. There's so much to learn and going big will just cost you more money for those mistakes. Start small and work your way into that grow room. Ok, not teenie-tiny. But smaller than three 600Ws.

Just my $0.02

Good advise there RedHairs...
My flower area is 7' x 7' x 8' half for the ladies half for me.
Running one 600w hps on a light mover, two would be better.
How I wish I had a 12' sealing... I keep banging head on the hood!
Venting the light heat, the bigger the better is my advise.
There is a lot of heat being radiated into the room through the glass.
This is where I hang out when I feel a little cold... Toasty!!!

1. I honestly believe I will use MH during vegetation and HPS during flowering.

get a switchable ballast or conversion bulb so you can use the same fixtures for veg and flower.

2. So now, would you think I would get an excellent harvest from using (2) 1000W or (3) 600W or (2) 600W?

let's say you use up 10 square feet with equipment and access aisle . so for 38 square feet you'd want to shoot for about 285,000 lumens to get to 7,500 lumens per square foot. that is exactly three 600 watt hps lights, which are the most efficient bulbs made. that's a lot more light than you need for veg so you may want to look into ballasts that can shift from 400 watts to 600 watts to save some electricity.

3. As far as carbon filters go, does it matter what size I get? I ask this because I plan to use a big one, probably a 4 footer if it exists....

i think you can find a size guide for carbon filters based on room size at htg supply. if not there, some other hydro site.

4. Should I run 6'' ducts exclusively?

large enough and lots of options for fans and filters in that size. you also asked about ventilation fans - for bringing in fresh air you need one room exchange per five minutes but you may need up to two air exchanges a minute to cool your room depending on the ambient temps you're dealing with. you also described this as a sealed room - do you intend to cool with a/c? have you considered enhanced co2? need to know a little more about what you're trying to do to help you more with ventilation.

Even more good advise, nice job desertrat...

Thanks for all the comments!

Yes I will be using a CO2 bottle in there. Need to do some research on this though.
And as far as the cooling/ventilation goes, I alrady figured that out. I will be using an AC attached to a thermostat. Whenever it gets too hot, it comes on and sends cool air into the room via its own vent. I may install another fan to help increase the air flow but I think it may be overkill.

Thanks again!

Hi,

I have a similar size room and using and ebb and flo. My sealed room is 11 x 7 x 8. There is no way I could fit 50 or 40 pots in here and my room is bigger. I have 2 1000 watt air cooled lights and 1 600 w in between them. My room is completely full with 15 pots. I can barely walk through to my veg room. I veg for 3 weeks. If you wanted to use a larger number of pots, then you would have to throw into flower from rooted clone, and if you did that, then why not just get an ebb & flow tray? The ebb n gro is made for bigger plants.

If you haven't used this system, I would recommend just buying the 12 pot with the extra 6 buckets to start with, because I really don't think you could fit more in your room. I love mine, it is really easy to use, so much better than soil!

I veg separately in an ebb and flow tray, then transfer. I then have the pots close together under 1 light, then spreading out eventually when they grow larger. Then I only have to use the extra lights when needed. I also use a co2 burner, a/c and dehumidier. I recommend using the 8' ducts, and get a good inline fan. I have an elicent..super! I have a 6" elicent on my filter and it eliminates all odors completely.

You could probably fit more than 50 if you designed a little vertical setup. I've seen a few neat ones that don't look so hard to build using some PVC pipe and tupperware containers (video on youtube somewhere). Would take some thinking, might have to adjust the type of watering system you're using as well.
