First 4 strains were transplanted about 2 weeks late from solo cup's to 3 gal pot. Started on 180 watt Grow Blu LED full spectrum. Switched to 600 watt visosun metal halide 2 weeks ago when transplanted. Have been training for Scrog under 1000 watt HPS. Planning on perpetual scrog with a veg room. Other strains still in solo cup's.

Pictures are 2 weeks old. Will update on the weekend

thats some hot soil . they look great though good job!

For germination I fill half a solo cup with straight ocean forest and upper half a seed starter soil. I do this so as the taproot moves down it gets nutrients but initially doesn't get burned when transplanting during germination

June 13th transplanted to 7 gal air pruning pots. Final container. Small one in middle is Colorado cookies

Blimburn GDP is doing the best so far with vigorous growth. Feeding with 6 tsp Big Bloom, 3 Tsp Grow Big, 2 Tsp root stimulator. PPM 680 in distilled water. Not showing any I'll affects. Does anyone think I should add anything else. I plan on slowly introducing plants to tiger bloom and when beginning flowering in the end of June. Cal mag when flowering.

Whenever I transplant transplant to a bigger pot I LST the plants. Planning on setting up the scrog in a couple weeks as well.
