Dendrobium Species and Hybrid

[LovePhals]

Hello all!

I am trying my first year at keeping some of my plants outside for the summer to free up some indoor space. I have had my Dendrobium Capituliflorum, Dendrobium Micro Chip and a Phal Noid outside for about 3 weeks and am also thinking about placing one of my Phal-type Noid Dens outside for the summer. My Dendrobium Capituliflorum seems to have a suffered some burn while being outdoors. Is it too hot for this plant species? Too hot for Den. Micro Chip?

I live in zone 7 and am hoping the temperatures are going to be right for them now that it is hitting 90 I want to ensure I am not going to have them suffer from to hot of temps. Should any of these plants not be grown in hot zone 7 weather that will hit 100+?
