need some help with size of room..???

ok new to inside growing, plan on building a grow room i have 81" high, and about 91" length about 36" depth.. i plan on doing a hydro grow on one side with about 6 plants not sure about how much space that is going to take up? but i was hoping to have enough space left to do a small sog grow maybe 10-12 plants? what do you guys and girls think? enough room or not? any input is helpfull. almost forgot how much light would i need???
thanks for looking
smoke-out

whats that in feet?

The more plants you have, the smaller they must be... you can go sog if want, quicker turn around, smaller buds

You want maybe aprox 400 or 600 watt hps I would think

Wats the biggest area a 400w hps would cover?

Hello friend. There are many different considerations to take into account when setting up a room. This can be overwhelming. Hope this information, which I wrote several years ago for an article, helps you decide on a suitable light source.

The plant needs light for its energy supply. Because we are talking about growing indoors, we will have to supply a light source. Normal lamps are less suitable for the job. A plant needs light of certain wavelengths, which are not or not present or strong enough in normal lamps. I recommend the use of type SON T lamps. They are suitable for both the growth stage, as well as the flowering stage. Ballast's are necessary for these lamps. Ballast's of 600 watts have the most favourable output of delivered light per watt. Depending on the variety I recommend to use between 400 and 800 watts per m2. With insufficient light the plant remains light-green in colour and becomes unnaturally thin and protracted. The buds will also remain smaller with insufficient light.

Saving on light is stealing from yourself!.

The efficiency of the lighting in the grow room can be strongly increased by covering your grow room with reflective materials. You could paint the walls with mat white paint or cover the walls with white plastic. Ensure that the room can be easily cleaned because spraying might pollute the walls quite a bit. Most sorts of your "favourite plants" remain in their vegetative (grow) state when the light cycle is maintained at 18 hours. Your "favourite plant" is a so called short day plant, in this we mean that the plant will start flowering when we shorten the light period. Plants are initiated into the flowering phase by shortening the day period to 12 hours on and 12 hours off per 24 hours. Your "favourite plants" that originate from the tropics do not react to changing day lengths but flower after a certain time. That is logical if you realise that a day in the tropics lasts approximately 12 hours the whole year round. The lamp must hang at a distance from the plants that will not cause any scorching of the leaves. This distance differs with the wattage of the lamp. We recommend a distance of: 400 Watt- 45 cm; 600 Watt- 85 cm; 1000 Watt- 105 cm. Don't hang the lamp any higher above the plants than necessary.

Hope this helps.

snap, you don't say what type of hydro you want to do. If you cut the space in half that would leave each at 3x3'9", I think that 9 in there would be tight. 400W on the low end, 600W at the high end. If you provide a little more info I am certain that someone will give you a better answer. Good luck with whatever you land on.

sorry wasnt thinking. i was thinking about a dwc about a 30gal tank. how much room would i need for that?

about 7ft high about 8ft wide and 3ft depth

with that much space how many plants could i get in there? also how much light i was thinking around 6-10 plants and about 800 watts? not sure if i have enough room but thats what I was thinking let me know if im even close.

I'm not quite sure about if your still planing to do only half but if you are, and this were my space, I would probably go with the following:

600 watt light with a larger air cooled hood. DO YOUR RESEARCH ON HOODS!! there are huge differences. Becuase your so narrow, You may want to get a long Jumbo hood (like the magnum XXXL). A traditional sized hood would be put in perpendicular to the long edge of the garden, you might have problems running the air cooling ducts to it. hence my suggestion for the bigger hood.

The 600 is going to give you much more light to work with which means larger, tighter, and frostier buds. The 600 watt is also THE most efficient bulb in terms of lumens/watt.
You will have an inline fan that pulls air from the adjacent room , runs through the hood, and exits outside the room.
If this is your first time hydro I would really steer you away from DWC. I know it seems cool and all but it isn't the easiest hydro format to work with and this being your first time, you may just fuck things up. I would suggest a ebb/flow system. I really like the bucket based system but you probably don't have the cash for that. You can build a simple flood table for about $50 in parts. Much easier to deal with than DWC, specially in a narrow space like yours.

Cover all the walls in mylar as it will really boost the amount of light your plants are using in that narrow space.

6 plants is probably going to max you out in terms of space. top the plants once (fimming would be better if you can do it correctly) and flip them to flower when they are about 18" tall.

Depending on the plant you'll get about 10 pounds from that set up. LOL Seriously though, if you train the plants and don't screw anything up you should easily get 3 oz per plant.

thats some great info thank you, i was thinking about the 600 watt, and after reading this post i did a lil research on the ebb and flow and it does look alot easier, i know if i go the dwc route it is gonna be a pain to change the water. my next question is .. i did alot of looking at ebb/flow and i was thinking is there enough room for the roots? from what i saw, there wasnt alot of room for plant roots.. maybe i was looking at the wrong type tho.. well thanks again for the helpfull post(thats why i love this place allways someone to help you)

Well the way I used to do it before I got the buckets (which is slick but a little more pricey) was to have a table filled with hydroton. It was about 6" deep. For 8 plants it was 5 feet long and about 20" wide. I stuck my clones in little net pots and carefully inserted them in the table. All the roots grow out of the net pot and into the table. There is a ton of space for the to stretch out in. When you harvest, these huge blocks of roots come out. They are actually pretty damn heavy. After you cut all the buds off, you basically rip the plants out of the table and shake out most of the hydroton from the root mass to use it again (making a complete fucking mess if you don't think ahead...like tarps). You rinse the hydroton out, get as much of the root material out of there and put it back in the Table. You use an ezyme like hygrozyme in the first few weeks of the next cycle to dissolve the remaining dead roots and stuff in your hydroton. Check out my medical SCROG thread in my signature. There is a picture of the table.

In general, you need a MUCH smaller pot in hydro. You typically don't see guys in hydro using 5 gallon buckets unless they are growing trees. Trees in soil need at least 10 gallon pots.

that answers all my questions thanks, cant get enough of this place love it here
that is one he** of a set up love it, wish i had that kinda room... but ill make something work. i thank you all for the help to get me started... now im waitin on the income taxes....
