The way to build farms in Tekkit Lite is by using a Planter, Fertilizer, and Harvester from the MineFactory Reloaded mod. The Tekkit Lite Wiki page on Planters has a couple of great diagrams on how to do it. I love diagrams--all the knowledge without the tedium of watching a video.
The diagrams were absolutely fantastic--precise and easy to understand--but I still had trouble. My planter seemed to plant just fine, but then that is the only piece that worked. When looking at my fertilizer and harvester, it seemed like maybe they were faced the wrong direction, but placing and replacing them from every angle changed nothing. I searched and searched:
"How to get Havester/Fertilizer from MineFactory Reloaded to work?"
"How to turn the Harvester or Fertilizer from MineFactory Reloaded"
"Tool used for Harvester in Tekkit Lite"
and came up with nothing. This was a few weeks ago, and is seems the Tekkit Lite Wiki is on the ball, because they've now updated the description to mention exactly what I needed, the Precision Sledgehammer. A couple of clicks with that, and my wheat farm worked like a charm.
I changed it once to a tree farm my using saplings in the Planter and only putting one dirt block in the very middle with cobblestone all around. That also worked like a charm.
My mining buddy and I, at the time, were needing quite a few waterproof transport pipes, so I decided to change it to a cactus farm. My advice is: if you're trying to grow a cactus farm in Tekkit Lite, remember to replace the soil with sand! I forgot about that somewhat obvious step and was stuck for quite awhile. My second piece of advice is: don't make a cactus farm this way. It does technically work, but the fertilizer doesn't do anything to the cactus. Bonemeal won't work either. The cactus has to grow at its own pace, and that just takes way too long to be an efficient use of power.
Here is a much better alternative:
This version of an automated cactus farm still works beautifully in Tekkit Lite (version 0.5.7). We only changed ours to have glass on the top instead of wood, so it looks like a pretty little cactus greenhouse. If you have any other problems with MineFactory Reloaded machines, I found this site useful: github.com/balr0g/MineFactoryReloaded/wiki. Happy Farming!
