Timmy! Posted June 17, 2008 Share Posted June 17, 2008 Its been updated now with the new lights and corrected values for the enviros, thanks for the feedback.growroomtools I'm trying to use the 20Watt (100Watt) GE energy savers, you can get them for £1.37 from Tesco (with a buy 1 get 1 free deal) are these bulbs suitible for growing in terms of light output and wavelength? Thanks. Link to comment Share on other sites More sharing options...
distracted Posted June 17, 2008 Share Posted June 17, 2008 They will get your seedlings and cuts on the go but for flowering plants I'd say no.... plants need the energy from light to grow and 20w lamps just don't do it IMHO when you want to build bud as they don't emit enough energy. Personally, I started my first grow with an 11w aquarium strip, moved up to 6 x 15w cfl's, then + 2 strips, then a 600w all in a few weeks as m8's put me straight (got 2 cooled 600's in the same space now).... plants need light just look how much grows in the garden in the shaded bits, not big fat stinking cannabis plants thats for sure! Also if you are on your first grow and haven't read up much then read up on carbon filters before you flower! Link to comment Share on other sites More sharing options...

kuken Posted December 13, 2008 Share Posted December 13, 2008 a metric one would be cool seeing as most tents and such are advertised in metres. Great tool! Link to comment Share on other sites More sharing options...
djay Posted February 11, 2009 Share Posted February 11, 2009 It's not that hard to use a converter via google if you cant work it out to be fair. Link to comment Share on other sites More sharing options...

discharged Posted November 30, 2009 Share Posted November 30, 2009 Still no 250 though :wink: If someone tells me the lumens of anything they want adding I will add it. 250W CFL Link to comment Share on other sites More sharing options...
BluePixie Posted December 2, 2009 Share Posted December 2, 2009 Still no 250 though If someone tells me the lumens of anything they want adding I will add it. 250W CFL A 250w CFL should knock out about 18000 lumens IIRC..... An alternative calculator can also be found here.... this one is metric and takes some account of heatgain from your lights Alternative Calculator Thread Bluepixie GrowRoom Calc v0.4 download.
