in a 5x5ft tent - best lighting question

You will find an almost religious fervor regarding the choice between LED and HPS... They really both produce fine bud! I flowered my first crop with CFL and the bud was great! (But way too many individual light bulbs) As a technologist that's enjoyed dancing on the bleeding edge of technology for almost forty years I couldn't resist LED... The promises of cutting electricity costs in half while having the same results was too tempting. (unfortunately, too good to be true.) Having grown both as recently as last year, my preference is still HPS... Shame on the LED companies for false marketing... Wearing my farmer hat, I can say I spend way less of my time enabling the plants to get the most from the LED light. (Like CFL, most commercial LED systems don't penetrate deeply... requiring more time to maximize light on the leaves.) I grow the plants au natural... usually my plants are between 4 and 6 feet tall. Since I'm not using SOG/SCROG, I don't typically mess with the leaves for light-catching. So, if you're going to have to mess with your leaves anyway, and the plants are intentionally being kept short, LED provides a compelling argument... Otherwise, HPS is the way to go. Since I switched to solely HPS I stopped having to focus on getting the most light to each leaf... There is more than enough light to go around. I grew about 4 years in a 5 x 5 tent lit with a 600 watt HPS. Very respectable nuggets! Keep in mind that when all other factors are equal, the total power you use in flower will determine the weight of your crop. (A light that uses 600 watts of electrical power will produce roughly twice as big a crop as a light that uses 300 watts of electrical power.)

I reread your original post and I'm guessing your planning small plants... A 1000 watt HPS should yield at least 1000 grams of dried bud (not counting sugar trim). I would expect an LED that uses 1000 watts of electricity might produce slightly more... I would expect the slightly higher weight flower yield will produce slightly less medicine because of lower potency. Unless the LED manufacturers have gotten their shit together, the "rough equivalent" to the 1000 watt HPS yield-wise would be a 2000 watt LED. If this is your first grow, I would recommend starting with a single 600 watt HPS (providing 600 dried grams meet your production requirements.) By starting with a single 600 watt HPS you are picking up a very versatile light that is as efficient as HPS gets... You can later augment the HPS with an LED system if you really want LED and the price will likely be lower per watt than currently available. Best of luck!

so much wrong with that sentence.

Excuse my grammar i see the spell check trolls are now here mars hydro is a top led assembler they are rated 4.5 out of 5 in all categorys. With "kinde" being the #1 company but they also are #1 in what u will pay for one

not your spelling. your advice. mars is shit.

what is the warranty on a mars? and how much does it cost to ship it back to china for repairs?

what drivers do they use? what leds? what efficiency is each led?

There is so much wrong in this post that I don't even know where to begin.

Dude, seriously - just stop. Everything you've posted is completely wrong. It's getting embarrassing at this point.

Maybe start at the beginning... Maybe your mommy didn't give you enough attention... You can provide advice to the OP or keep whining at every other poster that tries... Choice is yours... Peace!

No way. All of that nonsense you typed makes my head hurt.

And btw - I offered advice back on page one, chief.

Does it bother you that the OP is still looking for advice! You can help the OP by pointing out my nonsense... Even if it makes your head hurt! Don't worry, I can help set you straight if you can let go of your "alternative facts" ...

Though i do think thats subjectice.
Im in a cold climate. Hps makes total sense for me.
Keeps my canopy nice and warm too.

Instead of the ambient temps being the same top to bottom. Its cooler down the bottom which the roots love, while keeping my canopy right in the zone.
