Well its been a long time since i'v done one of these. But here we GO!


Strain: Lambs Bread autoflower (mostly sativa)
Seeds broke the rooters November 7th
Indoor 4x4x6.5 tent.
315 CMH run off a galaxy digital ballast
6" can fan with scrubber for exhaust running about 60% power on a dimmer.
30 liter DWC (50 liter tote) - AN PH perfect 3 part, with sensi mag. Big bud, and rhino skin for later. (will also move the lid over to a 50(70) liter tote if needed.
RH 50%
74F ambient temp.
65F res temp. Have a chiller on standby if it wanders from this zone.
4 x 6" airstones run off an eco-air commercial air pump #3
2- 6" huricane clip ons, and a 8"

Created the tub for 4 plants. but am doing a test run on two plants first.

FIRST UP! The tent a seedling shot, and my first issue. Looks like my rapid rooters were wicking too much salts into them and started to burn. so for the rest of the week i flushed the pots with RO water once a day until the roots took over and i could lower the reservoir a bit.

Week 1

Day 1 res 65F 0 ppm sprouted nov 7th
Day 2 res 64F 280 ppm
Day 3 res 62F 290ppm
Day 4 res 65F 290ppm roots poking through!
Day 5 res 64F 280ppm
Day 6 res 63F yellow tips on one. dumped res. other looks good. flushed pots with RO. Reset nutes at a 1-1-1 GMB ratio , 0.5 cal mag ratio 300ppm
Day 7 res 64F 300ppm damage not progressing. new growth looks good.
