1000w is just too strong. Buy yourself an inexpensive light meter for 30$ to determine the actual intensity. Keep the light really far away to start with, maybe about 2000 foot candles. Even better, consider buying a MH conversion lamp, it will not be as bright, and the blueness will probably benefit the plant in the initial stages more than an HPS. As they get bigger and bigger, then expose them to the glory of a 1000w HID HPS!!! Make sure the floor is well reinforced to handle the weight of the pumpkins. :) Paul Mozarowski.

You're really going to grow pumpkins in a dorm room? How will that work?

how did that work? i am soo obsessed with pumpkins right now, and i want to try crossing Prizewinner pumpkins with Howden Biggie pumpkins. i want to try this now so it won't affect my halloween crop if it goes horribly.
