Dekeius Posted May 16, 2016 (edited) Got some trich seedlings which are nearly 3 weeks old. They were doing fine with just the plastic lid and were receiving sun protection from the soil mix and edges of germ box. However they are now a little red. So I have put a tshirt over them but fear this cuts out too much light. At the moment they get no direct sunlight but are outside. Unfortunately the image doesn't do the colour justice but they are red near the top especially. I was wondering about attaching a shade cloth directly to the top of the lid. Maybe starting with it doubled up. There is a lot of conflicting information on here about sunburnt trichs. Peace, Dekeius.

2XB Posted May 16, 2016 I've used cheese cloth in the past to filter the light and it works well but now I just use the smoky transparent tupperware containers, thats been enough of a filter in my experience :-) 1 Share this post Link to post Share on other sites
karl_marx Posted May 17, 2016 if you're planning on grafting like you mentioned in the other thread, don't worry about a little too much shade or even a little bit too much sun turning them pink. Once they are bonded with a grafting stock with enough light, they will pump up into spheres even if they themselves are sunburned lobsters. 1 Share this post Link to post Share on other sites
Strontium Dawg Posted May 17, 2016 A sheet of baking paper works well over the container too. Let's through light but not enough to burn them. 2 Share this post Link to post Share on other sites
zelly Posted May 17, 2016 if they are outside in total shade & and not in direct sunlight I would say leave em alone....... one thing i do is go from total shade to dapple morning sun then to full sun, stretched out over 3-4 weeks 4 Share this post Link to post Share on other sites
theuserformallyknownasd00d Posted May 17, 2016 ^ solid advise. Or start em under 70% shadeclothe then reduce it to 40% etc... It's easier to start em in too bright a light and add shadeclothe as needed I find. 1 Share this post Link to post Share on other sites
Dekeius Posted May 17, 2016 Thanks everyone. Karl Marx i am planning to graft but not every seedling so need a parallel plan. Will probably try a few things and see if anything changes. Share this post Link to post Share on other sites
Dekeius Posted May 19, 2016 A simple tshirt seemed to work. Some (probably not fully covered by tshirt or maybe receiving more radiation facing outwards) are still a little red. The green ones are certainly looking plumper. Share this post Link to post Share on other sites
