Growing Greatness: Lessons Learned 1.1
More observations and some pepper specific tips per request:
1. It’s easier to double up on seed and cut extras than it is to plant single seeds in 70+ cells and hoping for the best. I'm using standard 10"x20" bottom trays. 2"x2" Inserts with 2 seeds per cell have been the easiest and most effective method for me.
2. Heat mats: During germination, using a heat mat led to my peppers coming up faster and more consistently than my first attempt. I experienced the same rate of germination with/without the mat, but approximately half were delayed the first time around and led to inconsistent growth. I used a cheap Ferry Morse pad that plugged into my LED lights (link below).
3. Light’em up: Look at the specs for your light but don’t be afraid to hang your lights close to your plants. The sun is a giant flaming ball that will burn your skin off from 93 million miles away. Your LED is a bit weaker. If your plants are stretching, they want more. Skip the Brawndo and give them more light.
4. Get a fan: Air flow will help stems grow stronger and prevent growth of mold and mildew. Spend the scrilla and get your plants some air flow.
5. Fertilizer Considerations:
a. Expert Gardener Organic fertilizer (4-4-4) worked well in combination with the earthworm castings and soil mix I used. It does, however, smell like death and will not dissolve in water (it’s basically chicken litter and bits). It wouldn’t be that difficult to apply in a garden setting but for seedlings it’s a bit of a pain. I soaked it in water for a couple hours and applied the solution in the top of the pots, then poured the remainder in the reservoir pan.
b. I recently used a non-organic liquid fertilizer 6-4-4 (I know, evil me - it was an experiment, calm down). It was much easier to apply, but I only needed a small quantity and may have ended up with a higher concentration than I intended. The result was some burning in my tomatoes.
c. I’ve been paranoid about feeding my plants and when I started seeing signs of over-fertilization, I watered heavily for 2 days to flush out excess fertilizer. The damage was minimal and has not progressed, thankfully.
d. It's important to note that previously I had added some fertilizer in the reservoir tray (smelly chicken litter I mentioned). Now that I have watered heavily to dilute my last application (the liquid), I need to be cautious as there could be excessive buildup of fertilizer in the bottom tray. If I were to bottom water (pour water into the reservoir tray and allow it to wick into the soil), I could unintentionally over-fertilize again, causing further damage.
