Just to add another note on a DO NOT... for Hydro

DO NOT: Turn on your 1KW HPS BEFORE your nute tank is flooding and draining. You will stress the plants without water when the sun starts a-shine-in!!!
DO: Make sure you keep an eye on your nutes each day. Both PH and EC.
DO: Measure your nutes carefully when using a 3-part system. Some go (grow, micro, flower) 321, 222, 123... Just make sure you know what your putting in your tank.
DO: Flush your plants when changing over from Veg to Flower as well as taking down the lights for 36 hours (keep them dark for 36 hours before switching on the HPS) if you are using MH and HPS seperately. Same applies for multi-spectrum bulbs.
DO: Make sure your Carbon Scrubber is complete... before you need it. Once your plants start reeking it's a mad rush to finish it. Will post plans on another thread.
DO NOT: Think that just caus' someone posts that the plant will stay low it will not stretch!!! It will when you least think so. Top 44 stretched on me, and it's under 1KW of light!!!

Well.... will add some more as I learn the small mistakes I've made... I've also been blessed with the remainder of my plants all females. So finishing off 5 females... 3 Top 44 and 2 bag weed plants (some kind of strain that was awesome, saved the seeds). WW have been planted on 11/20 and are already showing 3rd/4th set of leaves on some/most plants.
