-Starting Week 3.
-We start using the normal dose of fertilizers for the growing period.
-It seems that thanks to CO2 the plant is not suffering as much stress as last week. It has reacted well to the defoliation of the withered leaves and to the beginning of the LST. The new growth has hit a push and does not show as many signs of stress as the previous leaves.
----------------------------------------------------------------
The growth has not been bad and is reacting quite well to the LST. Every day the tip is straightened again and I put a new cable to guide it again. Maybe I'm overextending with the use of cable and causing it too much stress. I think that growth could have been better if I had not been under constant stress. Maybe if I had let it rest one day I would have grown something else. Even so, I am happy with its development. The lateral buds are receiving a lot of light and begin to develop quickly.
About the temp. i recommend you to use what I used on my shrooms : Peltier.
You may buy a cheap water pump of 1/8 and plug to a Aluminum block and make the water circulate within the buckets. At the aluminum you put the Peltier (with a good thermal paste that's essential) and fix very tight, and at the hot side of peltier a good and large PC heatsink with a good cooler.
The Peltier makes the block cold, the water pass within and goes to the bucket making it cold. The peltier has two side, the chill and the hot, at the hot you must dissipate the heat otherwise it wont chill. SO... Chill it outside from your tent.
You must note that the pump shouldn't be much higher than the bucket. A 1/8 cheap pump could only lift the water around 1.5m, and that makes it loses the power of circulate water.
So:
Peltier (around 9 amperes would be enough for each tank)
Heatsink with cooler
Water pump 1/8
Aluminum block
12v power supply
And if it get too cold get an "W1209" and put the thermostat inside the water so it will turn off the peltier (if you install that way) when reach the temperature that you desire.
Colder water is best for the roots.
Good luck, any help just ask.
