â¢Posted by summersunshine The easiest, most fool proof way to grow Cattleya orchids in my opinion is to use the "Semi Hydro" method. LOL I've killed any orchid I've tried semi-hydro with. I know folks who have a great deal of success with SH, but I'm not one of them. Orchid bark or large grade coconut husk chunks works well for me (and I grow a lot of orchids). You can even grow the catt as a mounted plant though it will require more frequent watering if it is mounted. Catts, as a whole, require high light -- an unobstructed SE, S, SW or W exposure windowsill can work well for them. Best way to get orchid supplies is to attend an orchid show. Unfortunately, there won't be any in Michigan until January. In the meantime, Lowes used to carry an orchid bark mix that should do. Just make sure you pick out any bits of sphagnum moss they might have in the mix. (Having such is fine for orchids like Phalanopsis but tends to increase water retention more than catts desire.) Many orchids can be grown quite easily indoors. Plumeria typically require a dormancy period during which time they drop all their leaves. If memory serves correctly, during that period, water is reduced to almost zero. (You'd need to check further on that.) For the winter, a cool dry area may suffice for its winter dormancy period. Strelitzia can be grown inside but plants get HUGE. Definitely not a good long term houseplant candidate unless you have a good sized greenhouse to keep it in.

Yes, and some of those seeds will benefit from or need a period of cold to help break dormancy. So winter sowing will provide this in your zone. Most perennials won't bloom until next year anyway. So you really don't need to get them going as early as possible (or do you?). Do you have seeds of all of these already? Your list is so large. Can you narrow down to a few must-haves?

Agreed. Peppers are not pot. the type of light and the amount of time will not affect flowering. That being said, if you are trying to regrow vegetation, 18/6 wouldn't be bad and the plant will grow faster than 12/12 but don't do 24/0. They need some darkness. Notes seem high for coco being hand watered too. If you start to see shriveled new growth or dying growth tips, I would look to your nute strength first. In your type of application, you should be about 1/2 strength of where you are.

I had to decide and resort to keep my Hibiscus plants outside downstairs. I have already lost my White Hibiscus due to lack of sun light. You know how it feels? It is like letting go of loved ones in the unknown.
