lighting questions, making the switch to 12/12, water quality?
thanks people, i will go get a few more lights, a ph testing kit, and another exhaust fan. i kept the plants 6" from the lights because i was afraid of them burning, you don't think that will be a problem with them so close?
i recently read in cannabis culture that putting white sand on top of the soil around your plant is a good way to stop the moisture in the soil from evaporating, and it adds another light reflective surface.
1. do you see any problems with this idea?
2. wouldn't the sand eventually seep down in to the soil and change its composition?
and one last issue
i have drop light hoods over my bulbs. the big silver round ones, there actually 8.5" in diameter and have vent holes cut for the heat to escape.
if i add more lights i would not be able to fit any more hoods at the same hight as the lights that are in there now. my walls and floor are painted flat white for reflection. without the hoods i could fit 4 to 6 more bulbs in the room. with the hoods i can fit 2 more bulbs. i can also pick up some normal 23 watt fluorescent lights( the long rod bulbs) and run them on the walls facing in towards the plants.
3. would it be ok to hang just the bulbs without any hoods to reflect the light ?
4. should i place lighting on the walls facing in towards the plants?
all of your guidance is greatly appreciated, and again thanks for the super quick responses to my last bunch of questions.
