A big hello to all the cannabis growing gardeners...and all the other visitors that came across my grow journal. This week i need to change the reservoir again, the plants drink solution just as I add fresh water the EC stays at 2.7 and i need to add PK and Calmag so that's why. The weather outside is very cold this whole week around -18 degree Celsius at night...this made my reservoir water go under 15 degree Celsius. Since i ran the Spider Farmer UV lights i noticed some purples on my cannabis plants i think it's their doing....i run it now for two weeks the UVs ---------------------------------------------------------------------------------- The SE 7000 is hanged at 28 cm. over the canopy and runs at 520W. This whole grow's main sponsor is Spider Farmer.
