So I started my first grow about two weeks ago, I have been crazy busy with school and work and other stuff, so my plants have been basically chilling on my deck during the day, and then sitting under a few desk lights for the remaining few hours of light period. It is time for me to now get more serious about light, I came across these today and wondered if they would suffice, my designated grow area is a small (~4ft sq. and 5ft tall) also I only have 3 plants growing and do not really intend on starting more, space is very limited. The fixture seems to be intended to be a spot light as it has a photosensor, also the ballasts are built in to the fixtures, is this good/bad/indifferent. The claimed light output as well as how cheap they are($35 for 2 fixtures and bulbs) is what really caught my attention for such a small setup. Any input would be appreciated.
