FastBuds FBT2205 test

Pictures are day 15 from seed. Used humidity dome during this week to help seedling establish. Lights started at 50% and are now 75% power hung at 30 inches. I am using a living soil and inorganic nutrient regime. The living soil is established and maintained with NPK RAW Bloom Micros, Kelp and Cane Molasses bi-weekly. I used NPK regime before establishing seeds in soils and start of week 1. This grow will use a 5:1 light schedule instead of 20:4. I am growing in an uninsulated shed where temperatures can reach -15 C (5 F). A shorter dark period will reduce the chance that temperatures spike below 17C for long periods. This will also shorten the time that a 600W heater needs to kick in. My exhaust is recirculating air to keep room warm, so I set up a simple fermenting bucket to help keep CO2 levels up. Might not do much, but there you go. In short, I will test a more truncated light cycle and push the limits of my grow room in a below freezing shed without vastly increasing energy consumption with heating during the dark period. Let's see what happens.
