What can I do in a frozen ice biome?

[pups]

The ice sits in the water with a layer of snow on top and spawns mirus and ss at night. I placed 2 blocks of grass on top of the ice and planted a tree but it hasn't grown. Can I still farm plants on it somehow? If I put down a layer of solid lava layer blocks can I still spawn hotfoots or would it be too cold? How about rambeau if I put down peakstone?

Another sort of related question, is an ocean biome where theres no ice or snow the best place to farm plants because I can put down a layer of grass and have the water underneath it fertilize the crops? Does that work?

Is there an easier way than placing snow and firebombing it to make a artificial river?

Hi pups, there is a lot of information here: http://creativerse.wikia.com/wiki/Farming

Crops wont grow if it is too cold or too hot, the temperature variance is different for trees and crops.

You can easily test where ever you are simply plant a seed and if it says fallow it wont grow, crops do not need light, but trees do

I have a farm on the ocean, I needed to go down a couple of block to get suitable temperature but I was near a warm biome

Creature spawns do not care about temperature just block types, but if you spawn non lava layer creatures in the lava layer they will take heat damage, I did this to part kill "Thing" then go in and finish them off.

Water needs to be one block away from a plowed soil to work, but that can be in ANY direction including diagonally below.

As for your last question probably not, I have placed blocks 3 apart offset each row by 1 and then placed water on each side, its time consuming but works, and you need to remove all the blocks later.

http://creativerse.wikia.com/wiki/ is a great resource

The water under the ice of a frozen ocean is considered fossil layer and warm enough to plant crops.

While your tree comment wasn't a question: Saplings typically only grow in their respective biomes. In their tooltip, most of the requirements for growing a sapling can be ignored. The important one is "proper environment". You can litter a woodland biome with saplings and might never see one go "fallow" when you plant it. In grasslands, you occasionally get lucky with a cragwood sapling, but it's tougher. In desert, frozen desert, etc. you'll probably never get anything to grow, not even an elderwood (I believe those grow best in tundra, but I may be wrong).

I always have a route to a nearby woodland where I plant my saplings. Harvesting a full tree will get you plenty of saplings. The planted trees will be smaller, but they will more than make up for all the wood you harvested. This keeps my supply of wood constant, as opposed to depleting a forest of wood & having to find another. Pro tip: Using excavators on trees will clear them quickly, but it will not get you saplings. Also, by placing dirt on top of a tree & planting your sapling there, you can stack your trees. Very handy for saving space.

Here is such a farm I made on a frozen ocean. The walls are optionals but usefull to keep creatures out.

All you need as Nerdleywhiplash hinted is to remove the ice and place dirt/grass on the water below (that's fossil layer).
