You have a serious amount of tops there. How long did you veg?

34 days veg time from clone.

Topped every 3/4 days (except the bb) as I was going for some ridiculous bushes.

The largest Sour D easily has 40 tops, the SIS has maybe 25/30,and the BB has 12/14.

Looks like they were already topped a few times by day 12? I can't see how they grew that fast. That's amazing.

Yeah, I top as soon as I feel like they have a good enough root structure, and the
earlier the better.

It's my first time running this style of system, but the people I've talked to about it
all compare it to DWC on steroids.

What is the setup? Are the 1/4 clear lines nutes or air? If air, are all the buckets just connected at the bottom to the res and you change the water from there?

The buckets are all connected at the bases with 2" pvc. The pump
pulls water from the back end of the system pvc connection, and pulls
it to the front most bucket (control bucket) where I can add and monitor
my nutes with ease. No having to lift up a plant while i'm measuring at
all and I can simply hook up a hose to my return line and make it a drain.

www.cch2o.com is what my system is based off of.

Checked out www.cch2o.com That is different. Are the buckets just filled with hydroton?

Mostly water actually. Just a little hydroton in the small net pot baskets to help hold the plants securely.

They look like huge net pots. How high up in the buckets does the water go, more than 4" inches?

I believe it goes how ever full u fill the system...or set the float if your using auto-top off. You want to keep it at least an inch or so below the hydroton I think for veg, early flower. Then by late flowering the modules should only be half full to help simulate drought conditions I guess? I dunno lot of interesting info on those system out there if u look around.

Well my design is slightly different from theirs as I made some 8" net pots cuz I wanted to
get a huge rootmass with lots of hydroton to support a larger plant. I dunno if this logic
is absolutely correct but seems to be working so far.

They have all kinds of arrangements on the official site using all sizes of net pots, I think
it really just comes down to personal preference. Although, I do wish I had the extra space
for roots, it's something I've considered changing for next time.

The water levels are all the same as a regular DWC grow. Start at the base of the net pot
with the very bottom submerged, then once the roots start to poke out of the bottom go
ahead and lower it to just under the net pot and let the roots do the work. At the very end
I've read it's good to simulate a drought season by lowering the level very low as this will help
to increase resin production that last week.

Edit: glad I wasn't the only one who read the thing about the drought simulation.

Those are some serious bushes you have there. This is for sure one of the best DIY UC systems that I have seen. Do you think the chiller would needed in a basement(in MI)? I would love to try and adapt this to my perpetual op. Have you ran the SIS before. From what I have seen in other grows she yields monster dank buds.

looking forward to seeing those babys pack on buds.

Thanks, I appreciate the kind words.

I live in Co and it isn't exactly very warm here right now
in my basement, but I would definitely give it a try to see.
If you ran into problems there are several ways to handle
the issues heat brings.

I have not run the SIS but I have seen the genetics flowering
in soil and the nugs were very large but kinda fluffy. Well find
out what hydro can do with these genetics.

..Drool damn you got those girls HUGE fast!!! Cant wait to see the finished meds!!!

PS: I think you may need to add that extra light you mentioned earlier in the post soon =D

Well I might just have to give it a try. I have been seeing so many UC grows lately. Most of them having great success like you. I will be following closely.

Sub'd. Nice setup.

Thanks guys, I'm really happy with it all so far.

I'd update more frequently but I think the sporadic posts help
to really show the growth instead of posting every day.

If anyone has any questions on building, please feel free to PM.

Seems like every 2 weeks better shows the changes. I have 4 plants with about 20 tops. No where near what you have. They have about a week to get past the transition phase. I am going to gas them so much with CO2 they should bud like crazy and hopefully equal your output. I'll post when they start to look like something.
