Is 153w cfl/led lighting enough light to flower on...

Hey there, just my 2cents. Are 150w enough? Maybe. Rather than using the watts per plant you should look at the w/sqft since you can fit how many plants you want in a given space. You should aim for 70-80w/sqft. http://ledgardener.com/lumens-par-ppf-and-ppfd-measuring-cob-grow-light-output/ If you want to learn a bit more... A better metric to judge your grow light is PPFD and it is expressed in μmol/m2/s. To support a optimal grow during flowering a PPFD between 600 and 1000 is needed. ( https://www.ncbi.nlm.nih.gov/pubmed/23572895 ) We want to keep it simple so we stick to luminous efficacy (lumens per watt) and energy efficiency (% of the watts drawn that are converted to useful light rather than heat): - CFL bulb - 60 lumens/watt - 8% efficient - LEDs bulb - 90-120lm/watt - ?? % - HPS (medium power) - 100-120lm/w - 20% - Quality (white) led panels - 180-200lm/w - 40-50% There could be even more to be said about costs. I can't see any reason to get CFL lighting in 2018 rather than led bulbs that: - have higher lm/w - last longer - do not contain mercury! - emit a better spectrum - don't waste light in a 360 radius Many producers are going to stop CFL production, like GeneralElectric.

Stay away form CFL. LED bulbs are MUCH better. I would know, I use them. You will need between 30 to 40 real watts of LED per sq ft. For 1 plant, you need 1 or 2 sq ft (I grow 2 plants in a 2 sq ft area, so 1 sq ft per plant). So for 1 plant use up to 40 watts of screw in led bulbs, with the dome removed. I recommend using Phillips bulbs, they work real good. If you do want to use CFL, you will need 3 to 4 times the amount of watts, so yes 135 watts of CFL will do, for the same result that 40 watts of led watts will give you. Check some of my diaries if you want to see how they work.
