would a 250watt light be ok with a 32x32x63 tent?

VACAVILLE,CA.GROWER · Mar 21, 2014

Hey folks. I thought of buying a 32x32x63 tent or a 32x20x62 for a 2 plant scrog grow. Just wanting to know if these sizes of tents would be enough room for a 250watt hps light with a air cooled hood? Would I still have enough space from the top of the plants to the light?

So many factors to rule there is no right answer
typically 3x3 rooms could push a 400 4x4 rooms
could push a 600 and a 5x5 can run a 1k.

Generally speaking thats how it goes, your setup
might need more or less I donno thats for u to learn.

good luck with ur grow

Best investment really is a 600w ballast with dim switch. This means you will not need to re-invest more money later as you need more power, which you probably will. This is a great hobby and we all end up going a bit larger eventually

Most guys will recommend a minimum 400w especially if it is in a good cooled hood.

But if I understand correctly you already have the lamp, in which case you can definitely run it in a tent that size if it is cooled. No problem.

Technically speaking a 3x3 can use a 400w or 600w HID,a 4x4 can use a 600w to 1000w HID.

Just supply between 50w and 66w per square foot.A little under isn't all that bad...math...

3x3 = 9 square feet

400/9 = 44.44w per square foot
600/9 = 66.66w per square foot

4x4 = 16 square feet

600/16 = 37.5w per square fiot (too low IMO,would be better with two 400w lights)
1000/16 = 62.5w per square foot

no sorry. I still have to buy my items. I was looking at a small 250watt hps and a 400watt hps both with air cooled hoods. I was just asking around to see if a tent of 32x32x63 or 36x20x62 be enough space for me to scrog 2 plants. I am looking for info before I buy my items. Which ever light I choose, is it better to use more of a square tent like the 32x32 for better light coverage or does it matter?

I have a 20x36x60" tent and use a 400w. If I could keep it cool I'd use a 600w but it would be hard to keep it cool in such a small tent. 600w dimmable would be your best bet. That way you can always dim the lamp if it's too hot.

I do well with a 3x3x6 and a 250W light. Last run I pulled 4oz. It's enough for my head and enough for me to not have to run it in the summer if I keep it going from fall till the spring.

Good Luck and happy growing,

If you stay with the 250 there's alot of good guys here https://www.rollitup.org/indoor-growing/128751-250w-hps-club-help-guide.html
Look through, guys like cbt and grazzmon do very well, as well as others who's names escape me at the moment. Take a look!

ok I will be going with a 400watt dimmable light with a air cooled hood. So what size tent would be good for that? 32x32x63 since the tent is square for better light coverage? Or a 36x20x62, maybe 48x24x60? Is it better to have a taller tent? Again I am just looking to scrog 2 plants. So with a 400watt dimmable light with a air cooled hood. What tent out of the those 3 should I use? I wanna buy it today. Thank you for everyones help and replies.

As I said I have a 20x36x60" tent and a 400w, I scrog one plant and this is the result....

If I were to do it again I wouldn't get anything smaller than a 3x3.

I edited my post saying it is a tight squeeze for the filter, fan and light. Here's a picture.

Is that a 6inch fan? How close is the light to the top of your plants?

I just bought a 48x24x60 tent. should give me alittle more room for 2 scrog plants.

rwbrock · Mar 22, 2014

You will be glad you went bigger I have a 2x3x5 tent as well but run led. Regardless it isn't very big and you always wish you had more room. I grew in a closet 2x4x8 with a 400 and found two plants scrog or trained works pretty well for that space.

It's a 4" inline and where it's at it is 26" away from the waterfarm.

ok thank you. So how is the waterfarm system? I have seen those too, they look pretty simple.

They're very simple. I like it, the bucket could be darker though. The res gets warm sometimes.

should have sprayed painted it black or wrapped it in foil tape. you could have used one of those car window shades and wrapped it around your bucket. It would insulate the bucket and make it darker inside the bucket.

In a 32x32 area 250w is not sufficient enough lighting.

32" = 2.66667 square feet

2.66667x2.66667 = 7.11113 square feet

250/7.11113 = 35w per square feet.

It would be fine for vegging but a 400w HID would be needed for any decent flower growth/yield.

400/7.11113 = 56w per square foot.

A 32x20 area is 4.44446 square feet

250/4.44446 = 56w per square foot...a 250w HID would be best suited toward the smaller tent.

would a 250watt light be ok with a 32x32x63 tent?
