how many lights 2 plants

i have a 400w hps light just like to no how many plants should this cover anybody no lol

400 watter should cover 2-4 plants. So you should be golden

i grow 4 under my 400w

• A 250 watt fixture will supply enough light to cover a 2.5 foot by 2.5 foot grow area. (6 plants or less)
• A 400 watt fixture will supply enough light to cover a 4 foot by 4 foot grow area. (12 plants or less)
• A 600 watt fixture will supply enough light to cover a 5 foot by 5 foot grow area. (18 plants or less)
• A 1000 watt fixture will supply enough light to cover a 6.5 foot by 6.5 foot grow area. (30 plants or less)
