Lighting

[Pan the man]

So I have a 600 watt LED light set on a timer for 18/6 and another 300 watt LED I've been using for about 12 hours a day for extra light for 12 hrs ..will this hurt my plants or would I be better off not to use the additional light?....

probably not. depends on how close to the plants you have them.
do a little looking, i bet your 600 watt led is probably more like 150 watts, maybe 200, and your 300 watt one will be around 100 -150 watts. not a guarantee, but i'd bet a buck, sight unseen.
what size is your grow area, how many plants do you have in it, how do you have the lights spaced out, and how far away from the plants are they?....that's what you have to know to know if you have enough, or too much light

The 600 is actually 240 watts not sure on the 300 ...I wasn't so much worried about the amount of light as much as I am the extra light at only 12 hrs may throw the plant off as far as throwing them into pre flower ....I have 3 autos going now one has kinda went to flower way early at only 6 inches tall so didn't want the other 2 (which is 3 weeks younger to start bc of this extra light)

no, as long as they're lit up solidly for a certain amount of time a day, it shoudn't hurt anything. the period of dark is more important, that's what controls when the plant flowers.
if you're going to do that, i'd try to emulate nature, at least a little. use the second light in the middle of your cycle.
let the main light come on, run for 3 hours, then the secondary comes on for 12 hours, which leaves the main light on by itself for three hours at the beginning and end of the cycle. like dusk and dawn.
with autos, light doesn't have a lot to do with when they flower. they get going as soon as they reach sexual maturity. you could have the lights on 24 hours a day, (many do) and they'll still flower when they're ready to

Thanx man I appreciate the help

I picked up a bottle of CO2 yesterday and asked the guy working about the Fluence Spyder LEDs, and he steered me towards a 315 cfl.

fluence makes good shit, but it's fucking spendy. if you mean a 315 cmh, you could buy 3 eye hortilux top of the line units for the price of one fluence. if he actually said 315 cfl, just smack him in the head and shop somewhere else

No, I’m smacking myself in the head, he and you were right, I’m wrong. cmh.

Cost wasn’t the issue, I was more interested in potentially moving to a high end LED, which this Fluence seems to be. I guess it’s really intended for industrial scale warehouse grow operations.

I have moved my crap into a closet, out of a tent. I was concerned about the heat in the closet after I flipped. That was why I was thinking about LEDs. But as it turns out, I seem to be ventilating the heat rather well, as the high temps in the closet are getting to 81F. So actually, I’m fine right now with my lighting, and would be worried that if I went with the LEDs I’d be fighting LOW temps, not highs.

The Fluence Spyder does look cool as fuck though.

Use as much light as you can while keeping the temperature within limits and lights a proper distance from the plants.

So it will be fine to use the extra 300 watt LED for 12 while using the 600 for 18?..both lights are about 18 inches from plants...the temps are 70 during night and gets to around 84 at peak heat is this ok?

it's ok, but if you're running autos, i'd just run them both all the time if it doesn't make your temps get any higher that that

Cool man I thought 85 wld be way too hot ....I'm hoping my purples turn out better than this runt of a gorilla glue plant lol

 

[Roger A. Shrubber]

85 is ok since you're using leds. it would be a little too warm if you were using hids. because of the way they radiate heat, you want your temps in the mid 70s for hid, and the low 80s for leds. that keeps your canopy in the right temperature range.
