Hey again everyone! I loved doing my last grow and was overwhelmed with positive responses (people enjoy free weed, who would've thought!? ).
Almost a year after completing my first grow I haven't run out yet, but my fingers are tingling again to dive right back into growing. That's why I decided to start my 2nd grow and take with me all the learnings of the first one.
There's a few differences this time around, I'll sum up what I'm working with in a second but let's start at the major changes.
After I've completed my first grow I re-purposed the room I grew in and have now set up shop in my garage. Before I started doing so I measured temperatures/humidity during the day and night to see if it was a good enough to start growing in. I noticed that at night the temperatures dropped to around 12 degrees Celsius (~53F) even with the lights on. That just couldn't do because I don't want to stunt the growth in any way and bought an oil heater to get it through the cold periods during the night.
Something I'm particularly excited for this time around is the fact that I'm going to place a Raspberry Pi with a temperature/humidity sensor and a webcam inside my grow tent. The idea is that I can monitor the plants from anywhere (yay, interwebz!), and see overtime if I need to do anything to adjust temperatures/humidity. I'm a software engineer myself so I'm going to try and write the software myself as much as I can and will open source it so everyone can use it. I've adopted this idea from a post I came across on Reddit.
As soon as I got this set up I will update this thread with some picture goodies!
Now, on to the details!
Grow environment:
Secret Jardin DR120 (1.20m x 1.20m x 2m) grow tent
Lights:
Mars Hydro Reflector 192 LED panel (420W@110v; 410W@220v, PAR of 1200umol at 18 inch)
Tools:
- CO2 5 liter tank with regulator and CO2 meter (aiming for about 1500PPM)
- Lux meter
- pH meter
- EC meter
- Temperature & hygrometer
Bucket Size:
The idea is to transplant from a 1 gallon pot to 5 gallon smart pot.
- 4 x 19 liter (5 gallon) smart pot
- 4 x 3.6 liter (1 gallon) plastic pot with four holes in the bottom for drainage.
Medium:
BioBizz All-Mix
Ventilation:
- RUCK R125L ventilator (max. capacity = 370m3/hour)
- Carbonfilter
- Small monkeyfan for inside the tent to strengthen the stem.
Nutrients:
- DutchPro Grow (soil) A+B, 5 liter
- DutchPro Bloom (soil) A+B, 5 liter
- BN Ca Calcium 15%, 1 liter
- BN MgO Magnesium, 1 liter
- Canna PH- Pro Bloom, 1 liter
- Canna PH- Pro Groei, 1 liter
- Canna PH+ 5%, 1 liter
Strains:
- 420 Carat Feminized x 4
Progress so far:
About a week ago I've germinated the 4 seeds in a damp towel and kept them in a dark place for a few days. After about 3 days all of the seeds had sprouted so I went ahead and planted them in a 1 gallon plastic pot and watered them. About 2 days later the first plant breached the surface and reached towards the light! A day or so later the 2 others followed suit. Thusfar there's one seed that did sprout but didn't manage to see the light yet. This might still change though so I'm not giving up on it yet.
Here's some pictures of my current setup:
