i am alittle confused i am shopping for flowering lights and i read a guide that said flour were fine to flower with but is it true because my uncle thinks what matters is the lumens is what is most important about the lights not the watts so should i use different lights for flowering?

this doesn't answer my question really i want to now does the lumens matter the most is that what i want to be the highest for flowering cuzz i am useing 40watt sunshine flourescent lights with 2250 lumens color temp 5000k do i want better then that for flowering cuzz i herd lower the light output lower the yield u will get for your plant

The more lumens the bigger the buds, i use 3 heolgen lamps that puts out 1000watts

were can i get those and lumens is what i need to look at to pick out a light for flowering.i am only doin 4plants so probally 1-3 will be female but after that i am growing about 8-12 plants i am makeing a shed outback and haveing cords run from guarage to the shed and i want the best light i can get for the cheapest cuzz im going to need to cover alot of romm or enough for 8-12 plants so could u just give me all the advise u can token .i have ben reading all i can everyday for like an hour and i got hightimes magazines so i now quite alot just not about lights alot

was in your boat not so long ago i dont know much about lights as well

if you have the money get this one 52,000 lumen output £100 w/d some may say different but thats what i have and boy is it bright

halogens dont produce the proper spectrum, i don't believe.


lumens and spectrum is what you want to look for, you want to get more lumens per watt of electrcity used. you want to go by both... thats the best answer i can give..

think of it this way, do you want a light that uses 1000watts of elec and puts out 5000 lumens.. or a CFL thats 42 watts that puts out 2900.. the answer is obvious. with enough Compact Floros you can flower good, the tubes will give you a bad yield. an HPS is more desirable, but it gives off heat, and costs more. but a 400w hps puts out 50,000 + lumens.

You want a more blue spec for vegging, and orange/red spec for flowering. white both can work all the way through, those give the most optimal results

Here's a great post for you trusten.. Lighting & Lumens

While the lumens measurement is based on the sensitivity of the human eye to light, PAR Watts objectively measure the total watts of Photosynthetically Active Radiation (PAR) emitted by the lamp. It accounts for the nutritional value and is a direct measure of light energy available for all-important plant photosynthesis.
