Subject: Does the tempature of water affect the growth (height) of plant?

well..i got this idea from my fiend. but i didnt really get any info about it. 
This is my materials and procedure (this is a rough draft)...
     
     Materials- three seeds of plants (kind of plant unknown for right now)
                small pots
                water or water source (faucet)
                measuring cup
                soil
                thermometer 
                reading log (to record results and observations)

     Procedure- 1) Plant the seed of __________ plant.
                2) Repeat this 2 other times for a total of three potted pots
                3) place tape on side of each pot, each one saying eiter "hot",
                   "cold", or "lukewarm".
                4) Place 3 pots side by side near window (ledge of window)
                5) Everyday at 7am and 6 pm water plant according to thier
                   markings on side of pot (hot, cold, lukewarm) with ___ mL.
                6) For every other day, record results in log.
                7) Make table after ___ weeks and record results.

     some of these things are undecided but if i could just get your opinion on 
this project so far and give me your feedback. Thank you.
