I started this growth just 3 weeks before these pictures, with 2 autos: one Auto Widow and one Auto Somango. The seeds germinated fast, 48 hours after putting them inside a jify. Then I put them inside the 20l. pots I have (I made some holes to help the roots breath).
The first 2 weeks I had just one lamp on, but now that they are big and strong enough I start the second lamp (I use the TGL Star 60, a COB LED full spectrum light with the equivalency of 300W but just consuming 55W, and a temperature of 3500K).
The plants grow in soil medium (Heavy mix by Top Crop) with 20% of perlite by Plagron, with some Nitroguano and Amino Perlas by Top Crop. I also added a CO2 pad to help the plants grow faster.
