They are all around day 50 give or take a day.
The Blue Dream, a beautiful yet sad plant, she always has something to complaint about, with too much water or not enough, she drinks one day and not the next, not easy to keep happy, she felt strained changing from the Viparspectra 600w to the Budmaster II COB-X 6
Both draw 300w from wall but there is no comparison.
I sometimes look at this plant and think about the robot in hitchhikers to the galaxy...
The OG Kush, what a beauty, strong, powerful huge leaves, handles HST like she enjoys it. Does feel sensitive to N and had to take it out of her diet as much as possible, she makes beautiful buds in lengthy stems, she has a blueish tone to her, and the stalks are dark purple and makes for a beautiful plant.
Critical + 2.0 is a beauty, handled my failed fim attempt very well, is quite sensitive to nutes and gets burned easy yet recovers quickly.
The main cola buds seem very strong already and I think she might bring me some happy times later on.
Blue Kush, a easy no hassle plant to grow, she looks good and she has the best smell, it's very fruity and fresh, it's always a pleasure to get close to this one, remarkable structure, and if somewhat smaller that the OG Kush and the Critical+ she is bigger than the Blue Dream and has always looked healthy and strong. She is the youngest she is only 45 days old
All in all the COB have so far replaced my 600w HPS with lower power consumption and lower heat problems as the winter comes to a end here.
A very expensive but amazing piece of kit. Let's see how they make it to the end.
And my next Grow I will try not to use the Viparspectra during veg and make it 100% COB and see the difference..
