Im not looking for generic answers here. Ive been growing for a few years and know the basics. But ive been doing it SOG.
Basically im going to start a Medical grow. I only get x amount of plants. So i need those plants to be as big as possible indoors (regardless of strain). I was thinking of vegging them for 2 months in 10-15 gallon pots under HPS lighting, then hitting them with 12/12.
To be as big as possible/produce as much as possible will i want a longer veg time? YES Bigger pots? YES MH light in Veg? YES Also im not sure how much space a plant of that size would need. I was thinking about 10 foot squared? only for LST
I have 0 experience growing massive plants. Im used to SOG. xD
Your height is limited to your light. A 1000w HPS can only reach 4' so your kind of limited in height by the light. Of course if you got lots of cash you can add more light on the sides and go higher.
I have the same issue they tell me how many I can grow but not how big. So I grow as big as I can.
I have indicas and I veg them for 5 to 6 weeks than flower. That does not include 3 weeks of clone time. So start to finish around 9 weeks before flower. I have one sative for personal but she gets tall so I veg 4 weeks.
I allow 2 sq. feet per plant = 16 plants under a 1000 hps = 2 lbs
I don't use pots any more but when I did I used 5 gal. pails. I use raised beds.
I would veg under a MH if you can afford it, a 600 would be ideal, but the HPS will work you will get some stretch. I also recommend Super EYE HPS. If you only use one bulb use the Super as it has more blue in it. It is worth the money.
The other thing I have learned is that I get the same yield if I have 30 plants or 15 plants, I just veg longer.
Good luck
