If you plan on vegging that long, you're going to have to have at least a 600 per plant. If not a 1k. Or some sort of vertical lighting setup. Or some light movers.
Sounds like you might be a Colorado med patient? Or maybe not. Either way, those will be some really big plants. I can get two foot tall plants within a month, and that's topped. You might have to make sure you have high enough ceilings, depending on your strains stretch.
I am growing Platinum OG and Blue Dream from cuttings. I plan to do a half/half grow. I know that platinum OG is better with space then blue dream (BD seems to be a monster).
From the responses it sounds like I would need +2k watts? I was hoping I could get away with 1200watts (2x600s).
as much as u can have without having heat issues vent is key to growing trees but u need to give more info
After a month of veg I can only fit four per 1k in 5 gal, comfortably.
Maybe 6-9 in an emergency. But if you're looking to get the most out of only 6 plants, the more light, the better. If you want to use two 600s, you could just have two rows of three plants. And drop a vertical cool tube in between each row. If that makes any sense. You could get some pretty impressive numbers with that scenario.
600 watts per plant? That seems excessive. After 1 month of veg I usually have about 8 nodes, but my plants are only 6 inches tall, I can keep my 400 watt light 1 inch from the canopy. After 2 months I can keep em to about 18 - 20". They finish around 2.5 - 3 feet.
Again I can flower 6 plants under a 400 watt light if they're trained, but a 600 watt lamp might do you better. You could go more, but more needs to be known about your setup, ESPECIALLY ventilation.
What is the space of your room?
What kind of ventilation do you have?
Those are equally important factors.
sound to me that this is going to be your first time, my suggesting is to go with a 150w or even a 250w then upgrade to a higher wattage once you dial in your grow setup,
for example you need to control your feeding "what kind of nutes you going to use and figure out the mix", ventilation, what kind of medium you are going to use , what kind of filtration system you using for the smell . here are some of my boy johnny 150w on a TRACK SYSTEM grow back in the 80's.
