Update 7: 8.4.21
Okay, I've got a good buzz on and rambling seems appropriate (at the moment), so here are a few RANDOM thoughts on how and what I actually do when it comes to a grow. To be quite honest I've grown the way I do long enough now that even I have to stop and think sometimes before making a list for others. I find I just 'do them' without ever making note of them. If you find that to be the case during this grow, please let me know and I'll do my best to fill in the blanks.

- I know the DWC 'standard' protocol calls for a tub flush every 10 days. I haven't done this for years and find that being consistent with water temperatures, keeping a GAP between the roots and water levels, ph and nutrients as balanced as possible and GREAT not good or okay dissolved O2 can cut this down to requiring full tub changes ONLY 4 times during your grow. 1 on start, 1 when you first add nutrients (this will be once your plant has developed two sets of 'real' leaves - usually week 2 of your grow.), 1 when you change from veg to 'transition to bloom' or from veg to bloom if you don't do a transition and 1 final tub change when within the last 10-20 days and are adding Flawless Finish, Molasses or other finishing agent.
- This doesn't mean that if you have an issue with your plants you should not immediately do a tub flush and start from fresh, but I'd say for 20 out of 21 grows you'll find that four complete RESET and RESTART tub changes are all that are actually 'needed'
- If Growing DWC Hydro, it's my personal opinion that a good high quality, high output air pump that isn't going to batter your roots to death is tied with keeping water temps between 70-80*. If at all possible you want GREAT O2 saturation in your tubs, not just good. I use a minimum of two aerator stones per 5 gallon tub and have been known to use up to 4.
- If using 5 gallon tubs and NOT doing RDWD Insulating your dark tub with a lighter one can help regulate tub volume temps.
- Have a few spare 5 gallon buckets and an aquarium siphon pump (electric or manual) to help fill and drain your tubs. A short stool or riser also comes in handy as the tub being emptied will need to be higher than the one being filled.
- For me, I find DWC Hydro as opposed RDWC hydro preferable for many reasons: I don't really have the room for a reservoir. I find it easier to deal with 1 issue at a time as opposed to a RDWC system which can spread the issue over several plants and to varying degrees. Different strains often like slightly different nutrients, I find I can easily accommodate them individually with a DWC system. If you pay close enough attention and can catch issues in time, practically every issue can be dealt with - with a tub flush and restart. Turning off the O2 and not noticing for a week, just for reference; NOT a good thing.
