Tarp or no Tarp

i have a couple of plants growing outside of my window the sun starts to hit the plants exactly at 12:00 noon and stops at 4:00 pm.. the plants are too visible from above and i don"t want no problems... i decided to put a tarp over it before and after the sun hits...will there be a growth problem and or difference if i put the tarp when the sun is not hitting??? shouldi just leave the tarp off?

yes becuase 4 hours of direct sun is not enough as it is. but because that time of when the sun is at its most instence i might work as long as you keep them in that sun you wil be fine. and unless you have helicopters going over your house at a suspicious height then you are fine

i use a screen not a tarp it gets good sunlight still and no one can see check my link and see for yourself
