2x BlackStar 240w vegg. ??

[xXOnyxXx]

hey peeps i gotta Q for ya'll ... currently i am running 2x 150 hps in my vegg cab, thinking about switching up to a pair of the blackstar 240 LED's. the reason is to hopefully maintain temps at 72f to 78f during the summer months. any input will be greatly appreciated, thanks all !!

What do u use to vent your hot air?

 

[xXOnyxXx]

a blower for the intake and a passive exhaust, everything was great until i built a larger flower room and hadda move the vegg cab into a different area of the house now temps are running close to 8f higher.

i am happy with the way everything is growing but the temps are going to try to get outta control this summer.

I would get some T5s, hps are much hotter and stretch em a lot more. I dont know much about LEDs personally.

My BS 240 is doing a good job at flowering(and it did veg well)...but it has mainly red spectrums... so if you are looking at a vegging light I would get an actual vegging LED with lots of blue and white diodes

i get very little stretch with the hps during vegg, ya those boys get hot too, but i have ran t5ho vs. my 2x 150hps and they whooped up on the t5ho's

could possibly go with a single blackstar 500 vegg light ... do ya know off the top of your head if the 500 pulls 500w?

the blackstar 500 pulls a little over 300w i've been told, not sure if that's for veg models too or just the flowering. never used them personally but there's a lot of guys here that do and they can probably tell you if 2 of the 240s or 1 of the 500s would work for you.

thanks for the reply's guys ..

a 300w draw will be perfect come summer with the A/C on. honestly i'm thinking it's gonna take a 500 LED to give me the results i get with 2x 150 hps, the cab is 30"d x 48"w x 48"h.

black star is a good led, i'm sure you would be glad you have the 3 watt diods. My first grow i used one led and a dimmable 600 with a hps. The thing is the genitics in my opinion really was the key. I have a set of clones that are about 20ith generation or somthing like that and i ran the 600 dimmed to 400 and the blackstar "Bloom sprectrum " and the plants came out good, but man i had sone sativa from seed and they had soo much keef off it..........it totaly out did the clones. also ran the led on 24-24 and with a good air exchange ennded up recording neer ambiant temps + - 1 degree or somthing like that.
in my opinion 2 is too much if its only for veg or mothering, add some 26 watt cfls and call it a day you could also run a few timres on the lights. i did a 12/ 12 light schedule and subsuted the first 2 hours in the morning with the led so its kinda like a 2-20 and a 10-14 worked out good.

I'm currently vegging a 36" x 72" area under three Blackstar 240 Flowering lights. The plants are extremely dense and bushy. I think two would be fine for an 30" x 48" area.
