help me with CFLs please

hey everyone... at the moment i have 5 papaya seedlings at week 3 in a fog/bubbleponic system and a wonder woman in a 5 gallon dwc bubbleponic

my primary light is a 90w dual band Ufo LED light, they say it is equal to the output of a 400hps...

my question is how many cfls are needed in a cfl grow a 2 feet X 2feet square?? i know nothing about cfls accept that they run cool and thismight be a good choice for me because heat is a major issue for me in my space... let me know how many cfls idneed to compete with a 400w hps...

thanks

my guess would be about 400 watts worth

anyone tell me what i need to buy and where???

you want 2700k (bright white...i think) for veg and 6500k (day light...i think) for flower, go by the actual watage if it say equal to 60w but is it self a 13w CFL then you have 13w, look online you can get some high watage CFLs with bases

Nah man its 6500k for vegging and 2700k for flowering... heres a link to some info you need https://www.rollitup.org/cfl-growing/107992-tutorial-growing-cfls.html

Although I'm not experienced with CFL's much, I wouldn't say you could really get a close to a 400w HPS with them. The light penetration is just not there. Also, when using the higher wattage CFLs there are sacrifices in efficiency. What I mean by this is that the lumen/watt ratio gets smaller as the wattage increases. And no matter how big your CFL is wattage wise I don't think the same color frequencies can be met because they both use different chemicals. Each chemical produces different colors when electricity is run through it.

Sorry I just realized how high I am and how much this is turning into babbling sorry if it doesn't answer your quesiton.

Great info.

So 40 watts are totally fine? What would be the maximum wattage?

im almost at week 3 with my plants i have about 12 in my closet which is 2feet across 1footwide and 3feet high , i just use 2x65watt+4x14watt cfl tubes and that is working awesome atm

maybe i will just order another 90w ufo light and run 180w of led.. that should do it

get another ufo and hang four 26w cfls two of the 2700k and two of the 6500k

are those leds anygood ? i got told they were meh

my 90watt ufo dual band rocks out with vegatative... clearly smokes any 400 watt metal halide i have ever seen and promotes the heathiest green color i have ever seen... i dont know how one 90w would work on flowering... but i believe near all of the energy is transfered to light, and hps and metal halide are only like 10%

so wats ten percent of 400? 40 correct ? so really the plants only use 40 watts of the light as apposed to the led...

i love the led.. almost no heat signature and and stealthy as you can get.. i can only image what some more years ofresearch will provide
