Preflowering looks similar for any strain.

Google "cannabis pre flowering" if you need more examples.

Are the plants grown from seed?

Hello farmergiles - no they were purchased as clones.

farmergiles

Ah ok. So they should already be showing the odd pistill.

Preflowering usually shows around a month from germination. But because your plants are clones they have the effective genetic age of the parent plant- ie they will almost certainly be a month old or older.
So- you can flower them whenever they are as big as you want them to be.

What Cervantes is saying (I assume) about looking for pistill growth before onset of flowering is correct but should be irrelevant in your case.

When choosing when to flower them bear in mind that the plants will double in height or maybe even more during flowering. So you don't want to run out of headroom.
Also the effective range of 600w sodium bulbs is about 30"- if your plants get much taller than this then the lower part of the plant will not really get any useful light.

So I'd say you're probably about ready to go to 12/12 lighting.

Cheers FarmerGiles - absolutely priceless info! That makes an awful lot of sense from the perspective of the apparent "contradictions" that the books can present to first timers like myself.

Hello PharmGirl,

They appear to be doing very well; they're bloody huge (I think I've over done the 'veg' period!), they're all a consistant dark green & now into the 4th week of 12/12 photoperiod they have buds - question; 'blueberry', how long from initial budding to harvest?

I have to add PharmGirl, that as a first timer I've found (so far - fingers & toes crossed!) that this has gone a lot smoother than I had first imagined, especially with grow room conditions far from the ideal i.e. too hot, too humid.

On the subject of temp (the original purpose of this thread), I fancy having a play with LED grow lights. If they are truly are what the manufactures claim them to be, then that solves my heat problem instantly & of course they are a QUIET solution!!! Do you or any other of you goodly folk happening to read this, have any experience with LED's?

Thanks again PharmGirl for your interest.

Cheerio!
val

Probably about 8 weeks from onset but you'll have to make a decision based on how the plants look closer to the end.

Probably just as well it is winter otherwise it would be hotter .

LEDs may be useful as supplemental lighting but I haven't yet seen the heralded lighting revolution they're supposed to be bringing.
Low light penetration and prohibitive set up costs are problems.

I'm trying a 6.5W LED on my seedling. It just sprouted today after 2 days in soil under the LED. The lite puts off hardly any heat, I was worried my seed my not respond. My little cab I use for seedlings is struggling to stay at 70F. I'm thinking I'd have problems with low tempuratures in my veg and flower rooms if I used LED's exclusively. I'll stick with HID's.

valyard

Hello stoneric,

Thanks for the contribution. A quick query, if I may, to make matters clear - are your concerns regarding LED's simply about temperature? In terms of plant growth; is the LED comperable with your experience with HID's?

Kindly Regards,
valyard

stoneric

I'm just using one on my seedling for the first time, I have no experience with them beyond that. The lack of heat problem was just conjecture and based on my particular grow room. I still have yet to meet anyone here who has successfully grown from start to finish with LED's only.

stoneric

I shit canned the LED. You can't keep the lite close enough. Stretch city.

Damn things just aren't bright enough.
