The ones in my greenhouse go directly into full sun, the others go first to a spot on the patio that gets some shade from trees, then after a week or so there they go into more sun.

Mine go straight out to the green house ,but mine usually don't have leaves or new growth so its no big shock to them . I do have a sun shade up though but not much

We moved 3 years ago and I lost my big covered porch where I used to keep most everyone...it would get great morning sun and then shade. I'd harden them all off there and then slowly move them out into the garden. Now my only goal is to not burn them. So far every summer here, I've tried a new shady area thatturns our to be not shady enough and I burn some. I finally gave up and bought shade cloth this year.

They spend a week at the back of the covered porch where they get evening sun and I slowly move them into more sun. 2-3 week’s to get acclimated.

I have my desert cactus outside in a polyethelne tent, and they are now getting multiple days in the sun. And what is the filter of polyethelne? The rest of my jungle cacti and succulents go out into the shade of my deck or the dappled shade of my front yard. The method of getting these out is both complex and random.

I don't have any good transition spots in my yard to get them acclimatized to the sun. It's either full shade or full sun. So I bring them in and out everyday for a week, letting them stay out in the sun a bit longer each day. Seems to work fairly well, no sun burn since I started doing it this way.

Rob - If it's clear greenhouse poly then around 10-15% light reduction.

My office plants just got moved from their bright unobstructed (but tinted) southwest window directly onto my roof. The weather is cool and partly cloudy for the next couple of days/up to a week which should be enough time for acclimation.

I stick mine outside in filtered sunlight for about a week and then bring them in for the night because it gets cold at night when I start hardening them off. I repeat this for about a week or so then I move them into about 6 hours of bright shaded for another week. After that I start rotating them into the full sun for a couple of hours at a time each day until I feel comfortable leaving them out all day.

30% shade cloth (most of the time doubled) and hung by bungee cords onto the metal gazebo frame. I also use a tight woven window screen usually hung by clothes pins and a large umbrella if it's not windy.

So, the shade cloth worked for the most part. I double-layered for a week, single-layered for a week, took it down at the beginning of 3 cloudy days, and I only have 1 that burned- a variegated aeonium. Otherwise, everyone seems well-adjusted. It only took me 3 years to figure out!
