Q: I attend middle school. I have come to ask u a question about
my science fair project. the question is: what are the five
basic things a plant needs to grow, no matter what kind of plant
it is. I hope u will be able to answer my question. A: (see
Instant Messaging Abbreviation List to decode this answer) AFAIK
plants need the following basic things: water, light, nutrients
(nitrogen, phosphorus, potassium, etc.) and air (oxygen and
carbon dioxide). IDK what the fifth one is. Maybe it is
“darkness”. IOW, plants require a period without light in order
to prepare for the period in which they photosynthesize, using
light. IMHO, the fifth need is not soil because plants can grow
just fine hydroponically, which is a soil-less growing
technique. Hope this isn’t TMI for u. G2G, KIT
