Sun Covers?

[cannre]

Good morning,

 

During veg, we have been using suncovers (black and white plastic sheets with a hole for the stem) on top of hydroton  to prevent any light reaching the roots of our seedlings or clones.  We are concerned about the suncovers creating great conditions for damping off or other humidity related problems on the young plant's stems.  We veg under fluorescent lights and have a drip system set up for watering.  Are the sun covers really necessary?  Will the plants roots be compromised somehow if  some light gets to them through the hydroton? We know that light may encourage algae/slime growth but are not too  worried about that (we clean obsessively and can take care of that) just asking about the how the roots may react to some light reaching them.       

 

Thanks in advance for any help- we've learned so much from all of you!!!
