Hey i guys i had a quick question about my lighting. I'm on the last day of the 2nd week of flowing and i was wondering if i could switch from a 400w hsp to say maybe a 1000w. My grow space is 36'x24'x60'. Its pretty small but i was thinking of going with a 1000w to maximise my yield. I'm getting some pretty decent flowering (considering it is my first time) but i heard by changing to a 1000w makes a huge difference. One problem i have is i can not install ventilation because my grow room is made of metal but i can leave the doors open all day well the light is on as it's in my garage. Please take a look at the pics and let me know what you think. Thanks alot BM!!!

Ud be fine as long as you have a way to cool the bulb the only difference is your gonna get more lumens out of the 1000w vs the 400w
I have a fan blowing directly at the light and another fan that oscillates blowing on the plants and breaking the air between the plants and lights but there is no way I could set up a inline fan to the vents of the hood as I dont have the space and cannot cut through the storage box they are in
Try it high

1 kW is definitelly to much for that space. A 600 with air-cooling should would be awesome enough I think

Fox Farm Grow Big, Tiger Bloom, Big Bloom and will these nutes increase the yield ? what if there is a 1000w hps in the roome and the room is 6ft tall 10 feet wide and 15 feet long? can any 1 give me and idea on the yeild if there is 10 5 gallon pots under the light?

Man if you grow it right...you could potention get close to 5lb.'s, applying methods such as topping or super cropping will get you to this goal. Good luck. But i have a 600 watt HPS, and I highly reccomend you doing the same. 600 watt doesnt burn near as hot as a 1000 watt and it will also save you up to 50% on your electric bill compared to the 1000 watt.

Just stay with your 400w I ran 4 girls in ocean forest(plus some other additives) in 5 gallon buckets and the fox farm threesome of nutes my first grow and got 7 ounces from a small closet. Make sure the temp doesn't get too hot get a big fan and run it in there to keep those girls from getting too hot even with a 400 you're going to have too much heat in a space that size.

yeah thanks man but the room temps r good the stay from (74 degrees to 82 degrees) its a very big space so it dont heat up as fast in there plus there is 3 fans in the room alson im thinkin bout buyin a tent ? and add some ducting to reduce the heat.

I highly recommend going with this plan..I have a set up like that and it does wonders...check out my grow man...I think I'm doing pretty well with my https://www.rollitup.org/newbie-central/461371-600-watt-hps-cool-tube.html go to the last page to check out my most recent updated photos. I am in week 6 of veg and will be switching to 12/12 in a week. Can't wait to smoke both these strains when I am done!!!yeah thanks man but the room temps r good the stay from (74 degrees to 82 degrees) its a very big space so it dont heat up as fast in there plus there is 3 fans in the room alson im thinkin bout buyin a tent ? and add some ducting to reduce the heat.
