Could be H. glabrata concolor; and you are correct about repotting and care...

Many attenuata cultivar crosses look like that with the speckling. Seeing how H. attenuata has saturated the market that's what I believe it to be.

What I think it might be doesn't matter, both of the species mentioned above take the same care. Assuming the are different species, a synonym for H. glabrata is H. attenuata var. glabrata.

I can not remember the rule on including links, so instead I give you the highlights of growing information from LLifle, dotted with MY GROWING OPINIONS in ITALICS

*I love this website, but I believe the writer in South Africa.

Cultivation and Propagation: easy cultivation and relatively low maintenance, Propagation is easiest by removing off sets.

ME:

To make seeds is a gamble, some hybrids are sterile or semi-sterile (might accept pollen willing, but not make viable pollen or the opposite). It probably needs your help. With a small tool (paint brush, toothpick...) transfer pollen from one to ANOTHER PLANT, whatever else is blooming, including Aloe & Gasteria.

LLifle cont.

Haworthias are winter growers and are dormant in the hottest summer months.

(THIS IS AN EXAMPLE OF WRITTEN FROM SOMEWHERE YOU PROBABLY DO NOT LIVE)

I live in the PNW, it's too dark in the winter for the to grow, so should be kept dormant with less water. & we have cool summer w/lots of sunlight. If you live in the Alaska, Finland or somewhere way up there, NOTHING grows in winter.)

Growth rate: They are relatively fast-growing plants that offsets freely to form small clusters quickly.

Soil: They are tolerant of a wide range of soils and habitats, but prefer a very porous potting mix to increase drainage. For best results, use a shallow pot. <YOU CAN NEVER GO WRONG WITH ADDING MORE DRAINAGE>

Exposition: The plant needs light shade to shade, but will take full sun part of the day.

AKA; MORNING SUN, FILTERED BRIGHT OR LIGHT SHADE. THIS ONE WILL NOT LIKE FULL SHADE IN MOST PART OF THE Northern Hemisphere.

Watering: SUMMER; keep moist, not wet. WiNTER; Keep fairly dry, give a little bit when you water, you can always add more later. Winter weather is unpredictable, the sun might stay hidden for long periods. .

Fertilization: The plants are fertilized only once during the growing season with a balanced fertilizer diluted to ½ the recommended strength. (HERE's A GOOD EXAMPLE. If you are in the Northern Hemisphere, DO NOT FEED IN WINTER., Spring to late Spring)

Hardiness: Although the plant will survive mild frost if kept dry (hardy as low as -5° C) it should be protected from severe cold and prolonged frost conditions.

Again the italics are my growing opinions, and every grower has one. NO ONE IS RIGHT OR WRONG. If it works for you, then it's right for you.

It’s an H. attenuate? I hope it’s a hybrid because I already have more of the species than I need
