I try not to worry about res temps as I feel im blowing enough oxygen into each bucket to maintain health
as water heats up it decreases the amount of oxygen it can hold and if you think that high temps are gonna be an issue get a bigger air pump
30ltr per minute of o2 being blown into 15ltr res is double the required amount so this gives room for manoeuvre, even 20ltr per minute is still adequate, anything above 77 -78 degress id be concerned
also who came up with the idea of using the colour black for buckets as its considered a colour to retain heat lol
green would be my choice of colour, I do have some good design ideas on how to improve on the dwc bucket for easier use and maintenance
day 17
as stated ive swapped out the cfl for an l.e.d panel, the smaller plant on the left is looking slightly pale although both plants have had exactly the same environment and feed from the word go but , the plant on the right speaks for herself and looks about a week ahead of her sister
the joys of growing from seed lol
