interested in your grow, Himalayan gold can get big! I have 4 I'm runnin to test that are about 6 seeks old been flowering for 2. They are my tallest strain, taller than jack herer, and i topped the golds, left the herers alone. they seem to take nutes well and look like hardy plants. They are cylinder shaped and all the side branches look like they will catch up with the top colas. I expect them to finish at around 3.5 feet not counting the pots. Topping them helps but they will grow tall regardless, so keep that in mind. And if your in an apartment with ten of them.. Well it's gonna smell nice, hope your neighbors don't mind! Good luck, wish your ladies the best. They like to eat from what I've seen so could be a good yeilder.
