I finally got my first hydro gardening experiment up and running. Basically an aerating bubbler system. It has 9 pots in a styrofoam raft and 480 wequivalent Full Spectrum cfl's (across 2 bulbs)
I used Rapid Rooters which fit quite nicely in the 2" net pot. Now , I was under the assumption that 60-70F was good temperature with a drop down to 55F at "night". What I didn't consider was the germination process. Now I read somewhere that lettuce germination should take place with water temps in the 40's. 1 plant has emerged with some tiny little strong looking leaves. I can see a few other seeds that are morphing. A few others are too difficult too see due to the depth of the Rapid Rooters. I'm wondering should I drop the water temp down ? I've been maintaining it was an aquarium heater. Otherwise the natural temp is about 60F. This is now the 4th day since planting. TIA Stuart |

I'm in the same boat as you, starting in Hydroponics.. I live in Puerto Rico, so our temps are no were close to 60-70 and my lettuce seeds germinated in like 5-6 days...
They are a little slow but they germinate... mines are up and running ![]() |

I start mine in peat pellets and have had no problem with them. I started spinach last fall by direct sowing them in the hydroton, I just sprinkled them on top and let the E&F do the rest.

The medium itself drank up nearly a gallon of water from 9 of them. Last edited by stuartambient; 02-10-2010 at 06:39 PM. |

The thing ti remember about the peat pellets is go very easy on the water, you will kill your seeds easily with to much water.

Well I will wait and see. We're on day 5. I guess whatever doesn't appear in a few more days is lost ?

I would start the seeds in the grow cubes in a warm nursery flat, then transplant them to the raft when roots start growing through the cube. 40 degrees is too cold, keep the nutrient solution in the 60s-70's. As long as the ambient temp is cool too, you should have no problem growing lettuce this way.
