What seems to be wrong with my automated Lettuce farm?

I have a lettuce farm. It works and at the same time not work...

I've hooked everything up and it is partially working. This is what I have observed:

1. The Planter is able to plant any modded seeds.
2. The Harvester only harvests ONLY Carrots and Potatoes.
3. The Harvester can't chop trees.
4. The Harvester seem to take about 2 minutes to realize that something is actually ready for harvest (tested with Carrots) before harvesting it.
5. The Planter seem to take about a minute to realize that a plot is empty (also tested with Carrots) before planting on/tilling it.

Also, all the machines are hooked up...

• The QDS (Quest Delivery System) is the block with a "Mushroom Cake" on it.
• The pipes contain sludge (not used currently) for the quest (which is finished).
• The Sludge Boiler is directly behind (from POV) the QDS.
• The Lava Generator (power source) is underneath the Sludge Boiler
• The Harvester is underneath the QDS (proper position)
• The Planter is under that tiny patch of water in the middle... And it is hooked to the Harvester with Itemducts and to the Lava Generator via Leadstone energy wiring stuff.
• All machines are powered with Leadstone energy wiring stuff.

So, basically:

1. Is there any way to make it work faster and be more responsive?
2. Is there anything wrong with the build/layout?
3. Why can't I harvest anything other than carrots and potatoes? (The only way to harvest is to do it by hand; right click/breaking)

Bit old, but the likely issue is that you don't have a secondary item output. If all you have is harvester->pipes->planter, and you can't send the lettuce heads anywhere, things jam up. The reason carrots/potatoes work is that the plant is the same as the seed, so it can just send everything to the planter.

You'll want a chest to output stuff to, making sure the planter still has priority for seeds.

Since the harvester can only really do vanilla crops, I used autonomous activators on each of my lettuce plants with an itemduct connecting the output slots to a JABBA barrel. You can choose whether the autonomous activators right or left click, so by having them right click you don't have to worry about replanting the lettuce seeds. Yeah, it's expensive and takes up too much space, but it works pretty well seeing as harvesters aren't compatible.
