My 3800watt perpetual grow plan

i wouldnt use the MH to flower your plants. I would use the HPS to flower your plants. Use your MH for the veg cycle.

I agree with romdog, also if you wanna get a little closer to your goal, you should get rid of veg cycle & go with the Sea of Green method. it requires alot more smaller plants, but it helps maximize yield, ALOT! Also it costs more to veg a plant then to bud 1 so, getting rid of veg stage would save you about 20% of the cost to grow your pot.
