"competing for light [under one 400 watt]"

thats totaly bollocks, as long as they are not shading each other, then they are all getting the same amount of light.....but the further away any given bit of plant is from the light souce, the less light it gets,and therefore the less bud.

training and pruning aside, 4 plants under 400watts will yield 4 times more than 1 plant.


if you bump the number of plants up to , say 10, for example....thats where you start running into probs with a small light like a 400watter, not enough power, not enough coverage, thats where LST and SCROG come into play.
babystarbud Reviewed by babystarbud on . If young seedlings are Raised under 110 watts of flouresent grow tubes ,How long should they be under this light for before they are put under a 400 watt hps? The plants in question are femminised white widow and are about 2 inch tall now and have been growing quickly for three days under this light on 16/8 do you grow them for four weeks like this and then put them under the hps bulb straight on 12/12 or do you let them grow so big and then put them under the hps for 18/6 for four weeks?:confused: This Rating: 5
