Thank you, what do you think of my LED lamp ?

Is it enough light for them?

The plants look quite good. Whether it's enough light for reblooming, you'll just have to see. How many hours a day do you have the light on? Since I don't grow under lights, not my area of expertise, but the setup looks good to me.

At least 12 hours 6am to 8pm

Is it possible to ID them? I know that some of them bloom with white flowers

Unfortunately, if they didn’t come with a tag you won’t ever be able to ID them with 100% accuracy. Two phal hybrids with completely different genetics can look the same so the best you’d be able to hope for is to be able to find lookalikes so you can say “this phal looks like the named hybrid Phal. XYZ”.

I have a NoID phal that’s a dead ringer for Phal. Elegant Polka Dots but mine will always be a NoID because it didn’t come with a tag. It could just look the same but have different genetics.

Ok thank you

Eventualy I want to build a shelf for my plants

12 hours of light is excellent. That should get you good reblooming,

What do you think of a fertilizer in spray like this:

Miracle-Gro Orchid Plant Food Mist, 236-mL Canadian Tire

Spraying fertilizer on orchid leaves is pretty much useless.. They don't absorb fertilizer through leaves, which are covered in a waxy cuticle that protects the plant from dehydration. The only way that it would get into the plant would be by washing off the leaves, ending up in the medium where it could be absorbed through roots normally. Don't worry too much about fertilizer - it is the least important factor of orchid culture. Get everything else right and then it will help - orchids need it to build new tissue, but since they grow slowly, they need very, very little. Think of how a Phalaenopsis grows in nature, on tree branches. When it rains, small amount of nutrients from rotting detritus in the canopy will wash over the plant. Roots are exposed to the air. So the plants have evolved to extremely efficient in such a nutrient-poor environment.

For that reason, the ideal time to repot is just when new rots are emerging from the base of the plant, but if waiting risks losing more roots and possibly the plant, go ahead anyway, but be prepared to “baby” it a little by keeping the plants warm (a seedling heat mat works great) and humid, to slow water loss. I just invert a clear plastic bag over the plant and pot (unsealed) to act as a mini greenhouse.

Is it ok If I use a transparent but blue recycling bag?

Roberta, have you read this article yet?

Why You Should Foliar Feed Orchids (& How To Do It Right)

As the forum mod you should be checking what I post. If you still feel the same about your answer then I don't know what more to say.

So that article exlpains it better than I can but orchid mist does not need to be used exclusively on the leaves.

It can be poured straight out of the bottle into the pot, it is ready diluted, ready to use straight out the bottle in a safe concentration that won't burn roots or leaves.

PS: light looks good, might be a bit close, how strong is it?? If over 10 watts move it a bit further from the plants to start with and move gradually closer to find the right distance
