Sexing Plants with CFL over HPS matter when discussing time?

When sexing plants does it matter to use CFL over HPS when time is of the essence?:syringe::mushroom2:

I use fluors for sexing mine, less heat.

But to answer your question, no it does not matter.

To know the sex is to know the sex.

I dunno. wouldn't the change in spectrum trigger it a little faster? it might be by a negligible amount but a question worth asking...

Why should that mean it isn't real?

Its always worth knowing more. someone in the know jump in.


This is just for sexing.Maybe not the best light but put under 12/12 and they will show sex.

I'm not too versed in the warm spectrum CFL bulbs as I only really veg under them, but I'm sure HPS is a closer spectrum to that of natural light than the CFLs are.

It would certainly be a neat experiment, but a tough one to remove all the variables from...unless you were working with clones I suppose.

I'm willing to bet its about the same. Maybe a few days, maximum, but not enough of a difference to make a huge effort for. If it was, I feel like we would have heard something about it by now.

If anything, I'd say use the CFLs to save the life of your HPS bulb :lol:

If time is truly an issue just stick with the hps.  It will stress them a little going back and forth from cfl to hps.  The 2 weeks you'll be running the bigger lamp is negligible really. Your plants will thank you. Stick with the hps.

nah. I'm for just running the hps. the plants will obviously grow at much faster rate. I guess what it really boils down to is how much time the op has. if their is a specific window of time....run the hps as soon as possible.

again just :2cents:

i agree with rasjah the redder spectrum will prob help out getting the plant to turn sexier. wether thats hps or with the warm CFL. but the HPS will make the plants grow faster so maybe that will make them sexier the fastest..  dunno

all great info friends!  I would never go back to CFL once gone HPS.  If anything I'd take 2 clones of the plant before sexing, keep those clones under the CLF while sexing the mother under HPS. I believe it's approximately 2 weeks before sex on a HPS.  I never tried with CFLs but it makes sense to keep heat level low, energy cost low, preserve lifespan of expensive HPS bulbs.  Anyone sex after the 1st 2 sets of leaves, basically still a very young plant?  Will these get up to 1 or 2 feet when introduced to a bigger pot and HPS light?

this info makes me reconsider my objective, which is to control odor as long as possible.  So I'm thinking less growth under CFL (vs HPS) during sexing period would translate to less of a problem with odor.  Then i throw away the male plants.:syringe::mushroom2:

I dont know if this is the place to ask but this thread seemed close, if the flowering time for a plant is 6-8 weeks would it be a bad idea use florescents for the first couple weeks or a full month before getting a larger hps or mh after you switch to 12/12 lighting?

No, more power would mean the buds would way more.
Don't think I'd wait a month. Maybe 2 weeks.

Cool I figured the weight was gained at the the end of flowering but I guess not. I thought using flos led to leafier buds.

Flors make pop corn bud. Light and airy.

Most of the weight IS gained at the end of flowering.  Regardless of whether your using flos or HID.

So using a flo for the first half of your flowing time wouldn't be a very big difference to the plants weight but the buds would be more airy?
Side note: would using a bud denser like Gravity help this situation?

Your wrong on both counts.  While the weight is put on more during the latter stages of flower development, your first four weeks are going to put in a foot print for how much bud you will end up with.  If you give them a small amount of light in the first half of their growth then you end up with a smaller amount in the end of flowering.  Now would you get more with with flowering half with cfls and half with HID, sure.  But not as much as you would if you used and HID during the whole process.


And gravity is bullshit.

Yeah, I used to use Gravity but that shit is dangerous. I hate that I spent $30 on a bottle of it and now I'm going to throw it out because I don't want anyone ingesting that shit.

scared me away from it.

I still use their snowstorm because I honestly believe that one is a good product, but if I knew of another additive that would work just as well I'd drop it in a heart beat because thats sketchy bad vibes shit and I dislike supporting their company now.
