The big plant grows almost in front of the eyes and takes most half of the boxing. The hairs appeared in abutting leaves to the stem, I didn’t notice the forming cones at the tops. Height of the big plant is 58cm. The little plant has progressed in growth significantly. Unfortunately, the big plant has already begun to obscure the little. So I need to do something wise with additional lighting using ESL. I raised the lamp higher on 15cm at the past week. 1100-1200 is ppm of the big plant, 850/900 is ppm of the small. Ph is 5.5-5.65.
Lamps' ventilation is independent, it excludes the motion of odor from the box bypassing the filter.
Today I inspected cooltube and wiped the outside of it from the Biobad’s salts (they appeared during spraying). I discovered th dust inside the cooltube which blocks light. I had to disassembled and carefully wipe cooltube inside. To stop appearing a dust in cooltube I hung up a piece of gauze (on the passive blowing in).
By the way, dear guru, I’ve the question! Two air channels are not used, and more specifically, 275 liters per hour. The pump has 4 channels, 2 channel for each tank. If I’ll use 4 channel for tank working volume of 18 liters, will plant feel ok?
