much better than last time. if you remember, i had massive root failure from (I think?) low DO because of air pump failure in my res. I didn't catch it until way too late I probably had slightly more than an OZ for 2 plants last time
you asked what I'd do different next time:
4 plants is perfect for my area. 12 sqft. but 4 in one tub is way too crowded.
i've been sketching some ideas for a 4 site RDWC with the res outside of my grow room. and i think i'm going to add more HPS maybe at week 3 or 4 of 12/12. i had a small 400 HPS as a supplement but I'm thinking a 1000 HPS would really cause massive growth of the flowers.
so use the LED from clone to week 3/4 of 12/12 which will save money for electricity in the 24/0 veg stage. and i'm gonna let them get taller too since the 1000 will penetrate way more than the LED.
No offence but sometimes I have problems remembering what I had for lunch a day before so it's hard to remember details of every grow.
The 1kw HPS will certainly penetrate better than the other two lights so, yes, you could go taller if the space will allow it without overcrowding. I see several ways you could try different light and schedule combinations but without baselines they'd be hard to compare.
Looking forward to the next one...

since you are a HID guy, give me a guess how much heat a 1K HPS would give off vs. a 400HPS and the LED together???
that's my main concern with the 1k: i'd love to be able to use a cheap-o batwing reflector and not have the extra expense of the air cooled hood. i've also read that the glass in a air-cooled hood blocks lumens and UV? is that true?? but then what happens when the air cooled hood doesn't solve the heat issue? so many what ifs!!
i have a 6inch inline as my exhaust fan. i could easily hook it up to a air cooled hood which should get most of the heat from the 1K out of the room. so at least i have that option without the cost of buying a fan too.
a 1K would be about 80w/sqft which would be awesome too.
If neither HID is aircooled (and the ballasts are outside of the tent/room/area) the 1kw HID will put off about 25% more heat than the other two lights combined, imho.
Don't do the cheap batwing unless you have a LOT of cooling. That heat has to be removed and it's better to remove it from the hood than the grow space.
Yes, the safety glass in the hood *will* block some lumens and depending on the glass it could block the UV but that doesn't stop most commercial growers from using them and getting great results.
The aircooled 1000w would probably put less heat in your space than the SS400w and an uncooled 400w combined, you'd be surprised how effective aircooling is. If aircooling a HID hood isn't enough you have to find more ways (there are several) to remove heat. Simple.
One 6" inline fan can cool UPTO two 1000w hoods but that would need full fan speed. It'll easily handle 1 hood but if you *don't* cool the hood and you use the fan to exhaust heat from the room instead you still won't be able to get the light as close to the plants as you could if the hood *is* aircooled. Fans and hoods are cheap. YMMV...

10 oz would be better than I estimated but still not great g/w numbers since you added the 400w HPS to the flowering mix. With your planned upgrades, next time, I know you can beat that. Next time, skip the two weeks of dark and let them have the light that they want and see the difference.
Now we just need a post-cure smoke report, I'll do that for you when you send me some. (j/k)

hey SME, yeah, the last 2 were the biggest so I estimated 80g per plant giving me a 50, a 70 and 2 80's for about 10 oz total.
have tasted some of it and before curing, it's pretty effective. in a couple of weeks it should be really nice!
i'm not too impressed either with my g/w. but at least i have the quantity to get me thru to january when i can start my next grow due to incoming company around the holidays and then us outgoing to Mexico.
plans are in the works for grow3.0 where we've got a RDWC/UnderCurrent setup and a 1K to finish the ladies off. the SS400 will be used for the clones until maybe week 2 of 12/12. then the HID.
extra spacing b/t the 4 plants plus the 1K for penetration, I'll have alot less fluff bud from the middle of the plant down. just the limitation of the LED with taller plants.
Jebus, I hope 10 oz will last you until January, you still have a month of curing so that'd be like 5 oz/mo.
Where do you go in Mexico? I moved down there for over a year after I met a senorita while on a skydive trip. I was in Leon, GTO. but I've visited other places too. Great weather, awesome food, friendly people and beautiful women. Nice combo...
Are you buying the undercurrent or building DYI?
Yeah, the LED lights really don't penetrate well for taller plants but instead of going fewer-larger plants you could go with more-smaller plants if you really wanted to test the LED.

a decent haul. should have done a few things different but learn and move on to the next one. yes, got my drill and paint stirrer attachment warming up for this weekend. just need to pick up some ice. October is National Make Your Own Hash month after all!!!!!!
SME, no, i have to wait til January to start my next grow. so my haul has to last until March probably. But 5 oz a month sounds like a good amount to be tokin!!!!
we're doing a all inclusive in Nuevo Vallarta. I've been to Mexico City twice for business. Didn't see much but the hotel and the customer site. And then we have some friends who have a beach house in Rocky Point (puerto penasco) that we went to once.
I wish I knew Espanol. I'd like to find/travel to smaller towns and really get immersed in the local culture. But yeah, the weather, people and FOOD is awesome!! It's such a big country that it would take a while to see it all.
I'll be doing the RDWC as a DIY project. Most are retail $800 and I know I can make it for way less than that. And a lot use Uniseals where I'll be using Bulkhead fittings to try to leak proof it.
Now that I know I can get at least a half LB from 4 plants, my next goal is to double the amount with the same 4 plants. I have a max plant count of 6 which I want to stay under.
