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?

This will be the second ever grow [for my friend] using a hydroponic waterfarm a 400 watt hps carbon extactor fan maylar reflectors and ionics for nutes the grow room is now completly light proof and there will be just one plant growing to try and get the maximum yield

the only other question [my friend] has got is do you put the water farm on the floor or would it be better raised for emtying with the blue tube at the front

oh and do you just top the water nute mixture up or do you replace all of the mix once a week?

replies on that one please :thumbsup:
