Need help with grow room design

This is my first grow. I have had many successful mushroom grows in the past, but havn't tried marijuana yet.

I have decided to spend a few thousand to do it right the first time. when growing mushrooms, i spent a lot of money i didn't need to spend when i first started growing. So I really want to get everything I am going to need without buying things that are useless in the future.

A friend of mine uses a tent and I really like it. this is the tent I want to buy: http://www.discount-hydro.com/productdisp.php?pid=588&navid=32

I am dead set on using 1000 hps lights. I have seen my friend use a 400hps and then I have seen 1000 hps. The 1000 hps did a lot better. Another friend also told me not to waste money on anything less than 1000 hps.

So would 2 1000 hps lights work in this tent? its a 5x10.

My main concern here is space. I have heard that with a 1000hps, you have to keep the plant 4 feet away from the light correct? well this grow tent is only about 7 feet high. so that only leaves 3 feet of plant growth. is this okay? I want to use the ebb and flow hydro system. I dont think the table design would work in that tent with a 1000hps because there would be no room? maybe with the buckets there would be room, but i would have to buy the multiflow bucket system instead of building my own table ebb and flow design.

So what should I do with this tent? I really want 1000hps but I guess 600 would be okay if I cant work out this heaight issue.

you would save a shit load of heat issues with two 600 hps's.. My question is how many plants are you trying to grow?
and if you went with the 1000 watters you could always scrog them to save room.

I would have proper ventilation. I wouldn't put 2 1000hps in a 4x8, but a 5x10 would be okay right? a 5x5 space is best with 1000hps?

I could try the scrog method. that way I would only have to grow a few plants right? and still get the same yield as many plants?

really i am not to sure on what grow system to use. I just know I want a tent and 1000hps.

I would say about 8 plants probly, but I really dont know. I am just now starting to read all I can about this hobby.

so any suggestions would be really helpful.

Also I am really shooting for DANK weed here. More into quality over quantity. I also like quantity :lol:

Thank You :bigjoint:

quality over quantity is the only way to go.
I think the average rule for light is 70 watts per plant. I'm using a 400 hps for 5 plants on a aero/dwc system. they are very happy so. As far as a tent i wouldn't know. I have to use storage cabinets to be alittle more stealth. In the end a 1000 watter would always be better. Im sure someone with a hell of alot more knowledge than me will chime in to help ya out.

From the pot I usually buy, I am just not impressed with the 400hps compared to what ive seen with the 1000hps. I havn't seen any 600hps grows. I just like density.

I dont want to buy a 400 or 600 hps light and then a year later buy 1000hps lights.

Just want to buy stuff 1 time (not including bulbs, nutes, etc..) Maybe in a few years I will go even bigger, but i dont plant on it.

If you have the same lumens per sq ft and can keep it cool enough then it doesnt matter what wattage you use the yeild would be the same.

400w hps=50,000 lumens 125 LPW (lumen per watt)
600w hps = 90,000 lumens, 150 LPW
1000w hps = 140,000 lumens. 140 LPW

As for how many lumens you want for your space most will tell you to have 2000 to 3000 lumen per sq ft, however I like have 4000+ per sq ft to start with because then time goes by and my bulbs arnt cranking out as many lumens as before I still have more than the recomended amount burning.

In your case you will have 50sq ft and want to try to have 200,000 lumen or so for that area. Remember also the higher wattage bulb the farther from plants they must be. I would recomend going with 2 600w digital ballasts with good 100,000 lumen or higher bulbs, allong with air cooled fixtures and a good ventilation set up. I just dont think that 1000w are the answer for you even though your dead set on it.

wouldn't my buds be more dense and yield more with a 1000w? i heard you yield a half gram per watt.

yes you can use 2 1k watters

make sure you use at least 1-400cfm fan to vent them...or go for overkill and put 600cfm on them. it will be fine


we have the same tent manufacturer... i just have a smaller tent. im using the DR 120 which is about 3'11 x 3'11 and the same height (a little bit under 7')

i have a 1k watt in there no problems and it damn sure isnt 4' away... i think my 1k sits in a cooltube about maybe 2' (if that) away from the plants and the canopy sits around 82-84F

I am glad to hear that! would I be able to fit the 1000w in there with the ebb and flow table? or should I use a system that is a little closer to the ground? I really like the idea of ebb and flow. Just dont think I got the room if i use 1000hps.

i dont see why you wouldnt have room for ebb and flow

it couldnt be no higher off the ground than my aeroponics system

I am definitely gonna have to look through your grows.

how tall are your plants normally and how many do you stick in your tent?

or better yet, do you have a link to one of your grow logs that uses this set up?

Its not the wattage of the bulbs its the amount of lumens per sq ft that counts. So if your worried about dense tight buds use those 2 1000w or use 3 600w either is about the same. I bet even with the extra bulb the 600's would be easier to keep cool and there defently more efficient on the electric bill.


That 1/2 gram per watt estimate is exactly that an estimate and there are just so many variables that its nothing more than a guess and personally I would be pissed off if I only got 4 pounds out of my 3600w of light.

yeah its just an estimate.

I have read that 1000w makes your buds more dense because it has better penetration than 600w.

So many growers have told me to go 1000w and dont go lower.

I really just want to grow the best I possibly can. Money isn't much of an issue.

600w wont have the penetration of 1000w so the buds wont be as dense.

Maybe more lumens per sq ft or something with 3 600w, but not more penetration. right?

The weed I get from the 1000w is killer. I want to do what they do.

Incorrect... The 600w lamp closer to the plants than the 1000w giving you the same penetration.


Yeah people swear by those 1000w bulbs and I liked the 4 I had because I could use combo bulbs that are a MH and HPS filliment in the same bulb but I have better results now with my 6 600w bulbs even though they are arround the same amount of lumens.

i dont post whole (seed to harvest) grow journals because of my paranoia....

well at least not on this site... but i guess i could give you a teaser pic?



the number of plant count is more dependent upon your method of growing/pruning (i.e. lollipopping) and less dependent on the size or space.

you can work anything out

That looks great. are u using that tray to flower or is that just veg?

also is that table 2x4?
