How many CFL's

How many would it take to grow atleast a 1/4 pound every two months?? if i was using 100watts cfls

bump!!!!!!!!!!

way way too many!

I need to buy some used hps have any ideas?

how big is your space you will be growing in

hey, im looking to harvest a quater pounder every 2 months to. just for veg im using 15,000 lumens in a 4 sqft area. about 250 cfl real watts. or 1000 equivilent watts

That would be too expensive for all those bulbs and the wireing would be hell. you need more space to grow. I have 9 square feet and grew a QP in 4 months with 150watt HPS and 6 HO T5 flourecents tubes

damn wish i had hps lights. Alls i have is cfls shit sucks.

with cfls that ideal would frankly be imposible

With a four square foot area that's impossible unless you have several shelves going.

if your trying to produce a qp every 2 months your going to need at least 10,000 lumens per square foot. thats what the sun is. and your going to have to do everything right. u will have to grow like 4 plants and get one ounce off each, have two plants and hope u get 2 ounces per plant. only experience and skill can give you big crops

alright thanks..anyone know of anyone selling used hps lights let me know.

craigslist or your local hydro store. honestly hps is worth every penny IMO

i know i know but i dont have the money

get another job lol, sell crack.

rofl !!!!!!!

Hey there guys.. Im curious I have 75 watts cfl.. What could the lumens be? It doesnt tell me this on the box..
Im looking to grow about 4-6 plants, and going to get atleast 6 lights to start.. Im probably going to get 3 -2800k, and 3 -6500k.. Any thoughs on this from anyone?
I seen many guys on the forum that have had great success with CFLs, so I dont know why you are so down on the idea gardenman.. Did you ever see Humboldts pics from his CFL garden.. His arent even 75 watts.. Atleast I dont think they are..
Here is his pics..https://www.rollitup.org/grow-journals/29010-humboldts-growing-adventures-up-away.html

I recently baught a 400watt hps/mh , actually its still coming in the mail. Now I have been growing with 4 65 watt cfl and they have been doing a good job but all my research kept telling me to get a hps system for many, many, reasons. Like many of us on here im not a rich man so i had to search around either for a used on or something ..so anyway I went on ebay and let me tell you there are some GREAT deals on there...the one I baught was from a store its a 400 watt HPS/MH it comes with two bulbs, 400watt hps ballast, batwing reflector, AND theyn threw in a FREE timer for 164.00 with shipping it was 204.90 brand new..comparative it was a GREAT deal. the store has like 34 of them left or something like that, but if you choose you can bid on someones used one...I actully was bidding on one and it reached 102.00 I didnt bid anymore cause I was thinking that i would just get a new one if im going to go that high. but that 102.00 was with everything that i baught throgh the evay store. so I recommend you go to and ebay store or similar you can get some great deals. I cannot wait to get mine in so I can use it immideatly and see if i can notice a change ..IM POSITIVE it wll...smoke on on.....;peace

I am growing one plant in a space 6ft wide 8ft tall. The plant is almost 5ft high. I only have 2weeks till harvest. She is covered in bud! Im using 12 cf tubes 40w(different spectrums) And 2 mini cf 42 watts for the sides. My next setup I want to use a single light!

damn that is a good deal! i paid 500 for each of my 600's at the hydro store but they were brand new. picked up my 250mh for my veg box for 150 at the hydro store, used but with a brand new bulb
