Hydroponic Lettuce

Hey everyone, Good morning from the Philippines!
I just wanted to let you guys know that I have successfully continued my journey as a gardener by using hydroponics as my chosen planting method.

I sowed using cube foam as medium and masterblend lettuce as my nutrient solution.
Ph = 6.0
Ec = 1.4 (mb lettuce = 1.2 ec, Magnesium Sulfate = 0.05 ec
Calcium Nitrate = 0.15 ec. total of 1.4 ec)

I sowed 24 more lettuce seeds the day before yesterday (December 10) to make a total of 48 lettuce heads for next month's harvest.

I hope they all survive, I'm expecting at least 40 lettuce heads next month.

Some I'll give to my neighbors for free, some We will eat and the rest I will be selling to get a return on investment, since I did have to pay for Nutrient solutions and seeds, also for the upkeep of the equipments used (EC Meter, Ph down/up).

I would only need to sell at least 10-15 heads. Wish me luck! :)
