Week 2: Plagued By Algae and Mold

At the end of last week’s post I mentioned how I had noticed some algae growing on my rock wool. This week saw the growth of algae, and mold, go rampant.

Whilst I have dealt with algae before, never have I had it this bad! Something has changed within my growing environment; I suspect that as the weather outside turns warmer, the plant room now reaches an overall warmer temperature. This could be a contributing factor.

Unfortunately it seems that some of my seeds did not germinate, and most likely will not. Chances are I will discard the algae infected rock wool cubes and do a big clean.

Another means of combatting mold and algae is to increase airflow. Currently I have clear caps on the cups to increase moisture levels (seeds germinate better in high humidity). I may begin to remove the caps overnight so that they have time to dry out and get airflow, and return the caps during the day when the lights are lit so not to dry out the seedlings too much.

So far only one of my seedlings seem to be loosing the battle of life. It’s not too uncommon for seedlings to not survive, so I can’t be certain whether this is the cause of algae or not (it most likely is however). Initially the cotyledon leaves started to wilt, but it started to grow its first true leaves. However you can see that even those have begun to wilt as well.

It’s not all bad news. Some of the seedlings are growing quite well despite the algae. The Marbles variety seedling has grown its first true leaves.

I have a total of 9 seedlings growing their first set of leaves. There are 3 seedlings that appear sick (like above). And finally there are 3 seeds that never sprouted.

Honestly if 9 of the seedlings survive and grow into trees, I will be happy.

My seeds finally got delivered! Of course that meant it was time to clear out my hydroponic grow room and plant lots of seeds. Chilli pepper seeds.

With some clever organising I was able to make space for 15 net cups. Since the Fatalii seed packets come with an average of 7 seeds per variety, I decided to try only germinating one seed at a time. The seeds I planted are:

  • Aji Jobito
  • Bird’s Eye Baby
  • Bolivian Rainbow
  • Bonzi
  • Carapita
  • Chinese 5 Color
  • Habanero, Orange
  • Habanero, Pink
  • Italiano
  • Marbles
  • Mini Bell Pepper, Orange
  • Numex Twilight
  • Pimenta Caixo
  • Starfish
  • Trepadeira Werner

There isn’t much to show right now, as I have just planted the seeds into their respective net cups. Even so, it can be helpful to know how fast or slow the seeds germinated. Fingers crossed within a few days, or weeks, I’ll get some growth showing.
