Flower with 600w LED (actual 276w draw) or 450w HPS?

Flower with 600w LED (actual 276w draw) or 450w HPS?

LED is a viparspectra 600w
HPS is 450w with a batwing reflector


Cheers

I would stick with the HPS. Vipars are junk.

Truth. HPS still has it going on

Hps. need 380w draw led to get 450 worth of hps

Precisely-that almost 200W difference is hard to ignore.

HPS all the way until you get up to
a 1,000watt led, your power bill will suffer but after a few decent grows then I’d go hard on led’s to save some money in the long run if you continue growing.

Why not both

Get some quantum board kits, can not argue with the results using them.

Blurple lights like vipar are similar to hps in efficiency so if power draw = 276w then that would be the equivalent of a 276w hps more or less so Id definitively go with 450w hps If I was you.. but you could look at other more efficient LED.. whats your tent size?

Never heard of 450w HPS. Its madness!

Meant 400w hps lol my bad, and tent size is 2x2x5.6 which I’ve been reading is too small for a 400w hps. All the rookie plays!! Lol.

love leds to veg but have not found one i like as much in flower as the good old hps

Shouldn't be too small for 2x2

2x2 is a good size for 400 hps, that's 100 watts a sq. ft. of lighting.

Do you already own both lights, or are you still shopping?

If you can afford it, look into getting a 315 ceramic.

2X2 tent. Personaly i wouldnt run a 400 in a 2x2. Thats only 4 sq feet. 400 is for 3x3 to 4x4 thats 9 to 16 sq feet. A 1000w can be squeezes in a 4x4 tent.. Barley and thats 62.5w per sq ft.
Good luck with 100w sq ft in a 5 ft high tent

Changed my mind lol go with the viper. You didnt specify in your post you only have a 2x2x5 area

2x2.. Just buy a HLG135w @$185 and get growing.
I just looked at the vipar price, its 159 english pound, thats like over $200... and its a bag of shite.. Man you 2x2 guys have it easy...

A 400 is not much good for over a 3x3 or 9 sq. ft. for flower a 400 just doesn't have the penetration to achieve flower density past 18". Want to see how close you can run a 400 hps with good ventilation.
