Single Jack47

I actually started this grow with two seeds but only one survived ,it changed all my plans and it will waste me time .I was wondering how it would be a single plant . My grow "tent" is a hidden space that I transformed with my own means. 55-80-160 cm I used almost a teaspoon of GW mycorrhiza when planting the seed . I use the light with %30 dimmer , soil is biobizz lightmix . I only use intake fan for ventilation ,i won't be using the exhaust fan and carbon filter until bloom 2th week , have passive air out and thats enough. In the first days, I wet the top of the soil with spray and i always use root juice and fresh aloajell in water . on the third day 100ml water ph 6.6
