What's wrong with my compost?

[PapaRed]

Composter:

LifeTime dual tumbler
Contents:
Kitchen scraps - 10%
lawn clippings - 25%
leaves, soil - 60%
water, some pine tree needles
rotate drums daily

At end of 90 days, the compost is dark brown, damp, (no smell) but has many lumps ranging from baseball size to golf ball size. The lumps slightly damp, can be smashed between thum and fore finger, are fibrous.

So I figure I must be doing something wrong, but don't know what it might be? 533534

I'm a few months late, so hopefully you've sorted it out by now, but it looks dry/pale, which suggests you don't have a lot of decomposing organic matter going on. I would put a lot more kitchen scraps in there.

Do you still need help with this? Probably, you already solved this by now.
I would also start by adding more kitchen scraps.

To gardeners, compost is considered "black gold" because of its many benefits in the garden. Compost is a great material for garden soil. Adding compost to clay soils makes them easier to work and plant. In sandy soils, the addition of compost improves the water holding capacity of the soil. By adding organic matter to the soil, compost can help improve plant growth and health.
