talked to a friend of mine today who is a firearms instructor ......... he said he got an e-mail from the FBI that says they will no longer allow anyone with an MMJ license to get a CCW (concealed carry permit) i don't know if this will apply to anyone who already has both, or if it only effects new applicants. either way heads up brothers and sisters ...... the feds are restless
front range snowstorm... serious.
250K BTU heater as the final backup is fired up and raging...
Only hiccup on the forecast til done.
watchin the temp gague, hoping for the best, dry trimming sucks!

What do you do about flushing? Do the catch trays provide enough room to leech the plants and you wouldnt want them sucking that back up again right?
ALSO do you think the digital ballasts are worth it? I suppose I could always upgrade later, but I figure if I am just going to buy the lights one at a time then it would be do-able. I have a galaxy 600 and love it. I will also be runnning electricity to the room and will be using 220, ran from an intermatic timer. figuring 4 outlets in each corner of the room for each light.

If you're in soil and feed them right there is never any need to flush, it'll actually do more harm than good. Try to water until they are saturated, but no more. Use a soil test kit to monitor NPK and pH, if you keep the levels ~medium and stop feeding 2 weeks before harvest it'll work out fine. pH never needs to be adjusted if you use a peat moss based soil with dolomite lime. Most potting soils already come setup this way.
20 gal smart pots work fine but beds are even better, I use a 5x5 bed per 1kW with about 10-12" of soil in the bed.
I don't think digi ballasts are worth it. I actually prefer the spectrum of light that magnetics produce when compared side-by-side. However, the new Hortilux HPS is supposed to be digi compatible so that may have changed.
Also, I'm no longer a fan of vented hoods, you lose as much light as heat. I've never seen a clean piece of glass in a vented hood, even with filters you get a white film... so f-it, just get adjust-a-wings with hot-spot diffusers.
Totally agree on ballasts. I have tried both and see zero reason to spend double for a digital that you are sure to have more trouble with.
I respectfully disagree on peat with dolomite never needing to be pH'd. If the alkalinity of your water is in the 40-90 ppm range that is true. It is not true if you have high alkalinity water or if you use a whole bunch of NH4+ nitrogen...both of those things will change the pH in the root zone.
Because of the high pH of the water on the western side of the state I amended peat with gypsum instead of dolomite and actual root zone pH was maintained at 6-6.5 with no pH adjustment of the water the entire grow.
You gotta match your media, water and NH4/NO3 ratios to never run into pH problems.
Other that that, pH has never been an issue. It sits at 6.7 and never changes.
Many people, myself included, have used the same soil for nearly a decade without even having to flush water through it using my system. But it is tuned for 100% organic ferts.
A pH of 6-6.5 is too low for an organic soil system. I maintain about 6.7, but if you're not 100% organic the pH range you have is better.
I agree that you need to be careful about adding too much alkalinity to your soil if you have very alkaline water. However, I have never seen that issue in CO, even using well water from various sources that run up to a pH of 7.8. I admit I have never bothered to measure alkalinity. If you do have very alkaline water, the solution is just to add less lime. I typically add a cup of lime per 150 gallons of soil mix that is about 1/3 peat moss every cycle.
If you regularly use a soil test kit, you will catch any unwanted drift in pH well before it is an issue, however the only time this has happened was teaching hydro growers to use soil, they added ph UP to adjust the water/fert mix to 6.5 from around 4, as is typical with many organic ferts. This increased the soil's alkalinity to the point the pH hit around 7 and we had to find the cause... which was them adding pH UP without my permission, I never adjust the water. Other that that, pH has never been an issue. It sits at 6.7 and never changes.

Can I ask if you are in some combo of peat, compost and perlite?
I am looking to make the switch to organic indoors myself. Outdoors it proved to be simple as could be except my plants stayed greener than I like to see them finish. Have not smoked any yet so cannot comment on taste but I like to get them to fade a hair more. With western slope water I amended with gypsum as opposed to limestone and pH (SME extraction method) stayed steady at 6.5 throughout the grow.
Is the secret to start with just enough amendments that the food is used up by the end of the grow...and then amend again? I have no problem going 100 gallon smarties per light.
