Ok on the way are 5 Buddha Seeds Purple Kush, 1 Delicious Seeds Northern light blue, 1 Russian Rocket Fuel, 1 la diva, 1 critical jack auto. I have a 400w hps and will be using 3 maybe 5 gallon pots. I've heard the purple kush is a great smoke but not a big producer. If I'm looking to get 5 ounces how many pk do u think that would take? I've seen some pk get over 50 grams and some less than 20 grams. I have a limited space and can fit 4 plants tops and would like to train them. Given the seeds that are coming and my setup which 4 would u choose if u wanted 5 ounces..? Just would like to hear others perspective since I must choose and can't do them all at once
