Newb lighting question on auto seeds

Hey all,

This may sound like a really naive question as I've never grown with auto flowering seed before. Can you grow these still with 2 separate lighting setups. I.e, blue spectrum for veg and swap to red when flowering starts? Or do you need to buy specific lighting with both spectrums in single bulb?

I'm thinking you probably can but thought I'd ask as I'm interested in trying some auto flowering seeds.

Thanks all

Shiva

Sure can do Shiva, mh for veg & hps for flower or dual spectrum for the whole grow like im using. With auto's you can keep the lights on 24h until they're done but probably best to go 18/20h per day. Good luck

^^^^^^^ as stated above , keep to one light cycle. , due to their short life .
There many cycles to use :

24/0 - most breeders suggest ( great for CFL setups ) less heat and cheaper
20/4 - great alternative ( autos are NOT dark dependent as regular photos )

Autos are going into Flower/Bloom within 30 days. So normal ways of switching light is unnecessary.

18/6 - Standard recommended cycle ( same as VEG lighting ) - you can run from seed to harvest with this cycle - I use this one.

12/12 - from seed ( I tried this , but found longer light schedule is better for bigger buds ).
But will still work. I ran a LED panel 12/12 and got pretty good results.

Autos will flower on their own very quickly. Veg stage is VERY short ( sometimes barely a week ) , I do not reccomend TOPPING OR FIM. plants don't have the " time " to recover.
They move to quickly into preflower. But you can LST plants for more mains.!

I don't understand how you can grow a decent plant in such a short time with a decent yield. I need to go check out some images to be convinced I think! I've only grown with cfl's before so would stick to 24 for entire grow I think. Thanks for info though!

I currently have 3 autos going in my tent and 1 photo strain, 2 just started to show their pistils and 1 is a little over 3 weeks into flower. I've been running 20/4 the entire time but my 1 photo strain is really needing to be put into flower. Will changing my light cycle to 12/12 to flower my photo strain cause any issues for my autos other than reduced yield? Plants in picture: (Back left 3 week auto, back right auto, front left auto(she took forever to germinate), front right photo)
