In line 3 of his post, he uses both '0.5' and '60 days'.
0.5 is the multiplier for 'per 30 days'.
Given twice the time, your multiplier becomes '1.0'.

Under a 400w lamp, you should get 200 grams per month of flower time.
If you run flowering 2 months, that makes 400 grams.
If you run flowering 1.5 months, that makes 300 grams.
Those are your target numbers with that light.
stinkyattic Reviewed by stinkyattic on . Super huge Buds? Okay.... I have been growing in hydro for over 2 years and some of you have some seriously sick pics of monster buds coming off of your plants. I need to know just exactly what is the trick to this? Is it because of bloom boosters or what??? I bought some gh KoolBloom and will be using bloom boost for the first time ever. I'm averaging about 2 to 3 ounces off of 2 plants but I'm hearing shit like ppl harvesting like 5 to 6 ounces just off of 1 plant. I really am interested in this! Rating: 5
