# Help with GPKW calculations for my hydro grow

• None

4x8 6 plants hydro. I used two 1000w hid lights. My best plant, looks to get around 1lb, the others wont even come close. That said, the plant was dedicated to a 2ftx 2.5ft area. I vegged for about 2 months and flowered for almost 2 months. Id say 3.75 months from dry seed to harvest.

My thoughts are if I ran all of that same strain again, and didnt have any issues, I could get more, but lets just say I get the same amount out of all 6 plants. Now my middle 2 plants only have 2ftx2ft, the end 4 plants have an extra 6 inches on one side, making them 2ft x 2.5ft. I know that variable alone will make it near impossible to determine how much weight I got,but perhaps not. Anyways how can I figure out how much my GPW was.

I vegged for 2 months using a 250w led at 50% power on average, and I flowered with 1000w HID on 95% power average. I want to say I could get 5lbs out of a 4x8 in 3 months lol. .. I so want to try that, but I have to become a caregiver before I can even have that much weight in my state, which is why im not to worried. Anyways it might sound boastful, but I can assure you I got at least 1lb off 1 plant in a 2ft x 2.5ft area with issues.

As for the quality, i could survive off just this one strain, and just might, it was that superior to all my others too. So to those that want to say you loose on quality when you go for bulk. . .lol wrong.

This is also dry weight, 1 week after, all trimmed up, not cured.

So veg 18 hrs a day.

Then take the watts you run like veg 50% intensity of 650w for eg.

325w per hr. So 325x18 5.850kw per day.

Then say flower 100% of 650w 12 hrs per day.

650x12 = 7.5kw a day.

Veg 45 days would be 45x5.85kw =263.25kw total for veg.

Flower 60 days would be 60x7.8kw=468kw total flower.

468+263.25=736.25kw hrs for the grow.

Then multiply that by you kw/hr cost and you have the cost of lighting for your entire grow.

Say \$0.13 / kw hr.

736.25x\$0.13=\$95 roughly.
