question about growng with fluoros.

[jmann142]

sup, i wanted to know how many 40W fluoro tubes will i need for one pant to come out nice with lots of resiny buds.???

how many lumens are they

[PoolShark1321]

from what ive heard you need about 2500 lumens per sq ft or growing space, although the more the better I think. Im going to grow with these CFL's like 3 of these http://www.1000bulbs.com/product.php?product=4013 and
3 of these http://www.1000bulbs.com/product.php?product=4010 maybe more... but thats a little different then the tubes. You should still need the same amount of lumens though.

umm....i think they are around 2600 together, and there daylight 6000K(whatever that is). would i need anymore?? when is a good time to flower, and would i have to switch the the warmer bulbs??

poolshark, how many plants are you gonna grow with the 6 cfl's??

I had a cabinet 2'x4'x8' for years, kept adding fluoro 48" tubes (I don't use the CFLs, their 'wattage equivalency' claims are bogus, in my opinion) ... didn't really get acceptable growth until I had six 40-watt tubes ... when I finally got to twelve 40-watters (35,000 lumens) the growth really took off, but the weight and size were a hassle ... I wound up going to HPS, whcih made a BIG improvement ... use the 'GE Cool Whites' for vegging, and the GE 'Kitchen and Bath' tubes for flowering (they don't have to be GE brand, I just mentioned those because thats what I always bought at WalMart) ... you can grow top-quality plants under fluoros, but the yield and speed of growth is just so much more with the big lamps ... I still miss some things about my fluoros (being able to leave home for a couple days, and knowing my lamps won't burn my plants and home up, for instance) ... hope this helps ... :smokin:

This will be my first grow so im thinking like 2 cause im going to LST them so dont want to do too many.

And you need to switch to the 2700k warm lights for flowering, one common question that im trying to find out is do you take the 6500k daylight lights out after you go into the flowering cycle?

[the image reaper]

yes, switch them out for the 'red' spectrum lamps ... some leave the 'blue' also, for a 'full-spectrum' approach, but all that really does, is keep the plant growing taller, etc, ... the buds like the red spectrum for blooming ... :smokin:

[PoolShark1321]

Thanks a ton Green Cross thats the last thing ive been trying to figure out, so if you want to keep the plant small take out the 6500k CFL's when you go into the flowering cycle around the 3rd to 4th week.

PoolShark.

As far as I know, the plants will continue to stretch once you switch over to the red spectrum bulbs. There is really no way of stopping that, unless you use some training method. If you pretty much expect your plant to at least double its size by the time its done flowering, that may help you in space consumption.

Hope that helps you out JMann.

Peace.
