10 Plant Grow With 3x Mars Hydro LED & Autopot

This is not my first grow, but it is my first grow-journal. I am hoping this journal will allow me both to share my knowledge about growing and also to receive constructive input/feedback from more experienced growers.

This grow-room is brand new and this is the first grow since it was built. The new room is about 3 square metres and I have put in 3 lamps from Mars-Hydro. Compared to HPS these lamps will give 800 watts each. So I have a total of 2400 watts in the room.

Planted 10 seeds on December 17th - 4 different strains.

As usual, I'm trying to keep the temperature as stabile as possible to avoid stretching. With the help of a simple climate control system connected to the exhaust and intake-fans, temperature is being kept stabile between 22-24 degrees celsius. Keeping lights on 24/7 in the veg stage during winter months to keep the room hot. Also installed an electrical heater.

The biggest challenge so far has not been heat but humidity. Due to the dry winter air being sucked in from the outside into the room, humidity was only around 10%. To correct this issue I was forced to put in a humidifier. So far so good, but it is quite annoying to have to refill it with water daily. Will try to find another solution for the humidity issue. If anyone have any tips I would appreciate that very much.

Will update this journal regularly as the grow progress. Hoping all plants will come up. So far 3/10 is above ground. Questions, comments and friendly tips are always welcome.

The first image is showing the first plant to pop out of the soil. It's a Pure power plant and this is day 3 since the seeds went into the soil. The second picture shows a bigger piece of the grow-room.

Regarding the lights from Mars Hydro - Switched from HPS to LED early 2016 when I bought a Mars Pro Epistar 160 lamp for a tent. Based on the fantastic results I had with this lamp, I invested in 3 more lamps. These lamps are simply fantastic and I get better results with them than I did with HPS. The plants look more healthy, the buds more dense and they grow faster. The best part however is how much easier it is to control the temperature.
