Evaporation or Plant Uptake??

[Ray]

That question still cannot be answered precisely, as there are too many variables, they all change on a daily basis, and some simply cannot be adequately quantified.

• What is the temperature profile?
• Relative humidity?
• Latitude (it affects the sun's angle, hence warming)?
• Season (ditto)?
• Air movement?
• Pot dimensions?
• Type of LECA?
• Size of plant?
• Specific species or hybrid?
• How well established is the plant (i.e., how well developed are its S/H roots and do the extend into the reservoir)?
