new greenhouse help

Hi,

ok... the greenhouse is up (12-24 quonset)... concrete floor.

have a hydropharm ebb-flow in it just 'cause I had one... have mixed lettuce in rockwool in it now.... seems to be doing ok but just getting the buggs out it... never grown lettuce before.

have a 200W aquarium heater in the tank set at it's lowest setting so the roots get some "warm" nutrient but no light at this point in time (there's a 400W HPS on a track ready to go)

and when I'm out there I crank up a little kerosean heater... heat and co2....

adding some Little Buddy homebuilt clones to fill my space (I've got

12*12 and swmbo has 12*12)

intending for the tube setups to house quicky tomatoes and peppers.... and they'll get the additional light.

any suggestions?

like right now I'm using "2 scoops" (3 T) of miracle grow general purupose to 20 gallons of nutrient... it's a stop gap to be sure... but anybody got suggestions?

any tips on greenhouse bluebonnets?

Lettuce doesn't need a lot of heat to grow, but it does need some light. Green lettuce needs less light than red lettuce according to a report on some research I heard over the weekend. The red pigments are formed through the action of UV, so on cloudy winter days red lettuce won't turn red. You could use a broad spectrum lamp to help it out.
