Hello fellow grower Starting directly under the Mars Hydro FC6500, seedlings are doing very well (see inputs for distance). The dimming is at maximum power. The light footprint might be a bit oversized for only 20 cups. Technically, for a commercial crop you can stick 1.2 sq. meter of seedlings without any problems. _________________________________________________ Barney’s Farm seeds are as usual, very vigorous ! All the seeds germinated in 24h to 48h. I’m just waiting after the Vanilla Kush to come out from the soil. _________________________________________________ Cellmax BIO Soil is perfect, you can start seedlings with it without risking to burn them. _________________________________________________ Seedlings stage tips: - adding a rotating fan, far enough and on first speed, blowing very gently on the seedlings, will stop them going looney and stretching a long weak stem to reach the light. - fill up the cup with soil, give it a good watering, then plant the germinated seed in the wet soil. _________________________________________________ 24/08 Cup, Water pH 6.5, LT TB 25/08 Cup, Water pH 6.5, AG Bba K Bad Azz 26/08 Cup, Water pH 6.5, Vanilla
