:thumbsup:How many gallons do those power growers hold? I just bought some kool bloom powder myself. The hydroshop guy told me to buy the powder because it goes a lot further and will last many many grows. Good shit tho man! Those plants are getting huge. Good thing you started the bloom phase cuz usually plants will double or even triple in size after switched to the bloom phase. Nice first grow! I got like 3 oz off my first plant since I only had one girl. I using the basic 2 gallon reservoir waterfarms and I had to add a gallon of water to each one today. I will doing a regular feed next week and then a transition to bloom feed the week after and then full bloom the week after that. I will prolly add the kool bloom about 3 weeks into my bloom phase depending on the bud development at that time.
