For both you want a high K light…5000 to 5500K (color of the light) but at the same time full spectrum.
I don’t run anything but LED. I have this one for clones/seedlings. They make a 2 footer just type in Durolux in the search line at Amazon. I use both the 4 and 2 footer and both are great lights.
At Key to Life Supply, we suggest full spectrum with more blue light in veg for non flowering plants.
Several reasons ,1 is that we use more blue light in veg to help with a higher % of females and keep them stay that way.
In the Spring, the Sun is lower in the sky and opens up more blue light.
What I’m saying is HPS is not what we use in veg or lights with high red spectrum.
In flower heck yes more red spectrum regardless of the type of lights.
I’m using a 5K 100W LED from seed to veg and this light is waterproof I make a mess at times.

I use a HLG 135 Bspec for my mothers, clones, seed starting, vegging. Amazing versatile light that can dim from 30-170 watts with enhanced blue spectrum for awesome veg performance.
To answer your last question, LEDs are way better than HID. They’re a little more expensive but really worth it when you care about the final product. The one I recommend is the one I use, the iuminar iL5x 440W LED. It’s especially good for mothers and clones, it covers the whole growth cycle and has a wide spectrum as well. It has worked without any problems.
Infrared diodes with a specific wavelength of 730 nanometres are the best. These LED elements are the majority and are responsible for the rapid development of the plants. At vont.com you can see different kinds. The diffuser is made of transparent polycarbonate with high light transmission, which saves up to 30% power. Seedlings and mature plants need sunlight. Under the influence of ultraviolet light, the physical and chemical process of photosynthesis takes place, aimed at the production of carbohydrates and the development of the plant
