Sugar Breath

Sisters strains in other cubes started showing signs of roots so placed her in the DWC setup as planing to mother her for spring before switching to flowering. This strain hasn't shown any tap roots showing out bottom yet dispite have sprayed bottom of cube, bubbles are focused under her. To stimulate root decided to put a heat mat under the reservoir to cause some humidity in the tub. As for growth herself; Shes doing well, starting 4th set of leaves. Her true leaves so not too concerned over not seeing any roots.
