Lights

[Nik-E]

So, mh lights...when purchasing those; do they have grow lights or is it going to be a basic light? Any specifics I need to look for?

 

[go go kid]

you can look for grow lights or metal halide lights.
with the grow lights search you will get grow light packages
if you just search metal halide, you will get a mixture of lighting from showroom lights ,industrial light fittings to grow lights

Ok, so which do u recommend ...sorry I'm new to this. I helped my dad with a few germination here an there but never done the whole process all the way through. So I'm trying to make sure I do it right.

well its all down to space , what size grow are you planning? are you getting a tent or have you a dedicated room to grow in. any info you can give will help narrow down the options available to you

Ok, so I do have a grow room I plan on using. I'm still putting together the area I'll be using. But it's a good size space. A whole bedroom actually. My plants still a seedling at the moment. An I grabbed a couple grow lights from Ace Hardware. I do have some led's coming in the mail soon. I read somewhere, that MH lights are better for the beginning stage though, so I wanted to test that theory ‍

leds are very good for seedlings and initial growth, with one seedling i go with a 70watt to a 150 watt to a 250 watt mh and a 400watt. a 400 watt is a good strarting light for a 4 x 4 space.
whaty leds do you have coming?

a 400 watt hps for flower in a 4 by 4 is perfect but you can get a 600 watt dual bulb for the same price dont mess with anything less than 400 watts its a waste of money

Sorry had to ask my wife, I asked her to order me the 600 or 900 watts, she hasn't answered me yet. She's at work rn

the more light the better

i dissagree, ive had great results with my 250watt metal halide.

we can take a simple poll and see you may be right

do you use the 250 mh all the way through flower? show some proof then i will believe i take it you have pics?

i should mention thayt ivr only had northan lights from sensi seeds under it. ive yet to try my hindu kush or black domina under it. but northan lights respond well to any light

 

[go go kid]

no, no pix unfortunatly, the camera is a relativly new purchase anf ive had a 14 yrr hiatus if you read my scribblings below

You want ceramic metal halide, not standard metal halide. Standard metal halide will work, but you get less light from a 400w MH than you do from a 315w CMH.

i wondered why all the growers are useing the 315, thanx i never knew that

You're looking at around 33k lumens from a 315w cmh vs around 24k lumens from a 400w mh lamp. Main reason is the low frequency square wave used in 315w cmh ballasts makes the lamp much more efficient, compared to the standard 60hz AC sine wave in mh and hps ballasts. Also chm arguably has the best spectrum.

Ok so go with a 315 chm then?
