So I have two seedlings and I am thinking of switching them into their flowering state once they grow a few inches tall but I'm not sure exactly how. Should I just introduce them to 12/12 sunlight? Or should I use a HPS?
Use the HPS and switch to a 12/12 light cycle. Just remember that not properly vegging your plants will result in substantially lower yield. Good luck.
Feed them properly in the correct size container and keep them on 24/0 light, as for the bulbs it depends on wattage.
You won't be able to start flowering until the plants are mature enough to flower. They must go through 4-8 weeks of vegetative growth and when they start developing preflowers that's when you know they're ready. Putting them in 12/12 before then will only make them stretch until they rach maturity.
ahahaha thats even funnier than the go HPS comment i have been doing 24/0 this grow for the first time, and so far i can say i like it a lot more than the 18/6 or 20/4 i used to use. honestly, i dont think there is much point in doing a forced flower grow like that. it's a lot of resources and time used, with very minimal reward in the end. go big or go home!!
i am close to 8 weeks right now, but am nowhere near ready to flower because i haven't received my HID lights yet. i know it is different for every strain, but how much longer can i go in veg? i really want to blast the plants under the MH lights for at least a couple weeks before i flower.
