Things to Know About Lighting

First of all I want to thank everybody here. This forum has been a very good source of info and i'm learning a lot
I need some help and hopefully you guys can point me in the right direction.
Just sprouted 6 seeds of different strains; snow white,big bud and edelweiss all feminised. I know these are considered to be indoor strains but I would like to grow outdoors. The sun is very bright here and we have 13.5 hours of sunshine right now which will increase by another hour in the next 2 months. The area where these ladies (hopefully) will be located is about 20 meters away from a hps which is used to light the surrounding area after sunset and it does not belong to me so I cannot switch it on/off as needed.
Will my plants veg with this cycle? The hps is quite far away so do not know how this would affect the plant.
For flowering I can always find a way to prevent the hps light from reaching the plants but I want them to veg for a while before switching.Any suggestions?

Hey, ok i have a light ? for all of you. i have a buddy that works for the power company and he got me a few street light setups and i was wounding about this light they come with its Ceramalux with Alto lamp technology one is a 100watt and two other 600watt. the ? is it says to only use in a hps ballast but does not say its a hps. the code on the box says "C100S54/ALTO" that is for the 100watt only one with a box. if anyone has ever used or have heard about these lights i guess all i want to know is if they would work for a grow. thanks alot and hope to talk more with all of you

I have a fluorescent 18,000 k power glo aquarium by glo, light good for coral, thoughts on veg please?

"C100S54/ALTO"...........google?

I have a question...

Whats your views on using the sun aswell as hps / mh bulbs to top up on.. Will it shock the plant due to the different colours in the spectrum..? or am i right in thinking.. More lumens the better..?

Thanks..

unless you start bleaching your plants....And just to add a little something to this thread, the lumens per watt figure graphic on the first page of this thread is old. You can get 110 lumen/watt from hps,mh, and tube floros, and, as i'm rather involved in part of the "lighting" industry, They do have LED's that can hit upwards of 250lumens/watt (but are def. NOT avail to public yet). Those are "suppose" to be going mainstream in a 5yrs, assuming the world doesn't fall apart first. Also, anyone every heard of either plasma lighting, or heck, induction lighting? Induction is way to $$ for what you get, but the bulbs last 100,000 hours. Yes thats 100,000! /end of rant

By the terms "Bleaching" do you mean by too much light..?? If so then i don't think this will ever be the case, I live in Ireland..

To much light, yup. Anything more than 9,000-10,000 lumens per sq/ft is a waste. Heck 4,000 lumens sq/ft w HPS is blinding.

O.K. so is it better to start them on a certain side and slowly move them to the other side in oder to getb both spectrums..?

I would appreciate if some one can ansewer this queastoin
I want to run a 600w hps sodium in a warbdrobe with a cool tube
I want to grow good harvesting plants
would I be better with a 400w hps

how far dose a 600 watt hps need to b away from seedlings.....

wow.. buddy. slow down, you should always start young seedlings or sprouts under CFL lights.. or flourescent bulbs of some sort.

starting a young plant under a 600 watt HPS isn't really good for the plant. They need to be able to get used to having the light first.. with lower wattage bulbs.. then after a week or so using CFL type of lighting.. then move them under the higher powered lights. This is done to help avoid plant shock.. due to the high and steep amounts of wattage and lumens that HPS and MH lights put out.

Just trying to help ya out man.. but hey if it works out for ya.. then good for you and I wish the best for ya. Hope things go well for you!

peace

this is the best info on lighting ive come across so far thx for the info

i have a sylvania 120v spot glo light bulb i got at my hardware store. it says its for indoor growing. when i got home i googled it and found all bad news, but so far my plants seem to be doing fine. i plan to switch to metal halide in about a week or two (they are exactly one week). do these lights really not work, or is that just people who arent willing to try different things

They look fine but stretching. and the light wont be enough for the other stages

Anybody know where I can get to info on running 250w M/H and 250w HPS together...
The pro and cons...?

I've gone ahead and done it... Bit worried about the amount of energy it's using... and would like any info on this type of set up please..

My journal shows the two bulbs and my diy reflector...

Thanks for any help

let him know that u want to go pretty slow so no one gets hurt and so u dont ruin wat u have. so keep doing wat you're doing and enjoy having his company

Supporting troops that kill innocent people on a lie based war is wrong and make people who support them crime accessories.

I've got this "Blue Buster" "Full spectrum light bulb" 1100 lumens, on the box it says 100w, on the bulb it says 75w, 120v. on the box it always says "like sunlight in your home!" The actual bulb is frosted a blue/purple tinge.

Should I use this light for the veg only?? (in combination with some cfls)
