I was starting to worry, but my seeds finally popped and little tiny sprouts are showing...boy are they tiny..I guess I expected a huge leaf to pop out immediatly lol. I went with the green leaf. Cant wait to see what it will do.
I'm still waiting for mine, low temps haven't been helping but it rained today and it's supposed to warm up over the weekend and I think I'll start seeing some sprouts... it grows fast! @willienelson1stgrow might be eating salads already lol.
Maybe too close to the light? I've always thought that indoors simple T-8 shop lights would probably suffice for lettuce. Also lettuce hates the heat if the LED is heating them up.
mmmm microgreens... I have zero experience with hydroponics and rockwool! Lettuce likes the cool temps though, around 60-70 degrees seems to be optimum, I doubt if it's a heavy nutrient feeder but I could be wrong!
In my experience the tomatoes will be fine in the trays but probably won't grow as fast as they would if they were transplanted. Last year I had quite a few in trays a lot longer than I should have and they stayed relatively small until I put them in the ground and then they took off. The ones I had transplanted into solo cups were much bigger starts but in the end it didn't really seem to matter.
What kind of nutrients?
Cheap Schultz all purpose plant food (powder that goes into a hose applicator, 1/2 teaspoon per gal of water). Nothing fancy or expensive. When the tomatoes or whatever gets a five gallon bucket, I use two part Dutch master flower hydro nutes that I have left. Since these are just garden plants, I have not been doing any PPM/PH checks at all as most will end up in soil outside. I will say, other than cherry tomatoes, do not expect to bring a full sized tomato to harvest under florescent lights. I have some under a 400W MH right now, and they are flowering.
Nice idea with the snowsled! It's hard to find affordable containers.
I've never grown greens indoors but in the garden I just let it grow, if you're getting two sets of leaves it sounds like all you need to do is let it grow longer. Lettuce likes the cool temps, if you're trying to grow it in the hot summer with your tomatoes and chilis it probably won't do very well. I'm planting a bunch more over the next couple days and I will pull most of it except what I let bolt for seeds by the end of May probably depending on the weather.
How's your lettuce going? Here's a question, do you keep your lettuce moist and give them plenty of sun? I water mine about every day that it doesn't rain.
