Things to Know About Lighting

These guys have LED grow lights that DO work. www.sunshine-systems.com. My friend bought two of their growufos and one of their growpanel pros. I have seen his setup personally and those lights are high quality. These are not the same ufos as the led ufo. These do not have an external ballast/power supply. It is self contained and much brighter than the led ufo. My friend has harvested his LRs and is working on some Purple Haze. He is very happy with the results so far and his heat issue vanished instantly. One thing he did said that was interesting was he noticed better yields when he increased the dark period by an hour during flowering. Overall, he said the yields were pretty comparable to what he was used to but he cut his power bill by more than half. He was running a 600w HPS and a 1000w hortilux. Their pro light covers 50 sq feet. (Really, you can see exactly where the light falls and we measured it). LEDs are here and they do work. I was a skeptic too but now I am a believer.

Hey i have a question. Im planing on growing my first plant and i was reading that you need a female and male seed to grow next to eachother. I have no idea how to determine that and i only want to grow one plant. do i need to grow both, and what if it is a male. does it still grow the actual bud. i was reading that only female produce buds

Wicked info! Really helpful, learning alot form this site! thanks ppl!

Heres a question that Im stuck with:

Where in the U.K. can I find a HPS bulb which I can use for the veg stage (blue spectrum)?

Ive been told the Philips son t agro is good but are these suitable specifically for the vegetative stage if not can anyone make any recommendations.

By the way if your think I should just use a fluorescent or metal halide bulb/s, that is out of the question as I have a different setup which cannot be adjusted

Is eight bulds of 54 watt t5, 4 red & 4 blue enough light to flower?

DUDEZ! thank you for this

how much does light leakage affect the plant?

...let me be a little bit more clearer.. if the plants are getting most of the light(say about +80%) and that leaves 20% of light leaking out(where it is not needed) - how much would it affect the plants?

Light getting out isn't really an issue, it's light getting in when it's supposed to be in the dark that's an issue.

ok. thanks.

i got 250watt hps light, i'm scared to set it up, i haven't got ventilation can it catch fire or cause and explosion with the bulb or ballast?

what would happen if the lighting was set at 24h light 24h dark? has anyone experimented

LOL what kind of tools do i need?

hahaha dude steeling lights and using them to grow bud is bad karma.. go buy some they're not that $$$ I got mine used for $150. thats with a brand new bulb.

awesome post...

Thanx to all contributors I found this most informative.
Ps.I'm sticking with my 400hps

So would I be good with a 400w hps bulb for all growth not just the flowering? I read through most of this and never saw it answered. Im going to start growing and just want to make sure I get everything crucial right.

well it is possible but u wont get the full potential of the plant. during the veg stage it likes more blue light while when flowering it likes more red light. in simple terms

yeah, well now I'm kind of confused. I read that article and it says that UV light makes more/bigger tricomes, so if I got a uv and an hps light when would i use what light?
or what about one of those hps with added uv rays, Im not sure what they are called.
