hey that doesn't actually seem to half bad for a idea! ^^

I'm pretty sure suggestions go to pull requests. It's not a bug @BluSunrize is supposed to be fixing.

No, suggestions do not go into pullrequests.
PRs are for contributing code.

It's not much of a suggestion though except for its title. You might want to flesh it out a bit in what you are expecting? Like, yeah, I get it, a treefarm, but how would it work? Would you build it around a tree, or give it saplings? What resources does it use?
You need to actually put some detail in here to start a conversation.

Same as Garden Cloche. only multiblock. and for trees.
it uses electricity for cut down trees.
simply, build a Big Garden Cloche with glass, dirt for the base, few light engineering block, light, a pipe for water input block, and woods. also, an engineering block to middle for SAW!
supply it with saplings. wait... wait... wait... and boom.. WOOD!

I would also like to see some sort of tree farming system, but I think it should be somewhat more realistic. The garden cloche is great for small plants, but no one would grow a tree in something like that. I'm thinking more like a grow pad with a harvester next to it, and once the tree is formed, a tree harvester head comes out and chops down the tree. Here is a video of an actual tree harvester

Of course I'm not imagining something that drives around chopping down trees in world, that would be a bit much, but the harvester head on the machine could be an inspiration.

And while I'm thinking about trees, a process like this could also produce a lot of saw dust. That could be used as a low efficiency fuel, or maybe even power a lumber mill/kiln, something that could for example produce 6 planks instead of 4 for the cost of some electricity and/or heat. Maybe even pipe in creosote oil and produce treated wood at the same time as part of the process.

I realize what I'm talking about would require a bit of work modeling/animating, but I wanted to provide my two cents.

Realistically speaking, plants and trees alike can be grown hydroponically. Growing trees this way causes them to grow much more quickly with the positive or negative side effect, depending on your application, being that the root system is much more fibrous. The tree has more effective roots for taking in nutrients but those roots are not as strong. So you could never expect such a tree to be able to grow as high or resist as much wind as a soil-grown tree.

Soil-grown trees are much more beneficial for the production of lumber. However, you can supplement soil-grown trees with a weakened nutrient mix distributed into the earth/dirt close to the tree.

Instead of Cloches for trees, you could make two new types of liquid, nutrient mix A and nutrient mix B. Nutrient mixers would take nutrient salts and add them to water.

The three top (most parts per million) nutrientsalts found in hydroponic water are Nitrogen (N), Phosphorus (P), Potassium (K).

So once you have the nutrient mixture, you can pipe it to a Deep Water Culture multi block. Could be variable sized depending on the users desire. 1 block high and as many blocks wide or long as you prefer. For trees that are for wood production, you could pipe it to a block the tree sits on that has dirt in it.

And lastly there could be grow lamps, to supplement or completely replace sunlight. The deep water Culture blocks could simply do a search for grow lamps within, say 3 to 5 blocks above and within 3 blocks horizontally.

Deep water culture systems have rafts on them which are how they are automated. Seeders drop seeds in a pattern on the rafts, the rafts travel closer to the end. How the fruit or vegetables are collected varies. In microgreens systems, the raft is sent via conveyors to a machine that chops along the top of the tray.

Edit:
Honestly though, all this sounds more like a side-along mod to Immersive Engineering. Immersive Agriculture, perhaps?
