Indoor Heavyweight Monster Profit Photoperiod Grow

Ah, rock wool, my old friend....
Love that stuff for seedlings and clones.
Hard to get here though. Pity.
Looking sweet!

The girls are doing well on day 12. The space has been running 68°F/60%RH night time, 76°F/50%RH daytime 18/6 schedule. Fertigation has not started yet as the Hugos remain heavy > 50% saturation. I want to wait until we're ~ 30% so the roots will become well populated. Lights are running ~ 25W each for ~250 W in the space right now.

It has been 9 days since the seedlings were transplanted into the Hugos. They were foilularly fed yesterday with 2 ml of Magic Green to 250 ml PHed water. The first fertigation will begin today. The drip emitters run 1.7 ounces of nutrients per minute per plant. The nutrients are at 870 PPM mixed on week three of the chart into 10 gallons of water. PHed to 5.9. the fertigating time and duration is shown on the chart. Each plant will get 34 ounces total today. Fertigating will then be turned off until the blocks are dried down to ~ 40% capacity. This is estimated by hefting them. This should take 3 or 4 days. Algen Extract is not added to the reservoir tank to keep it cleaner and will be applied separately to the top of each FloraFlex cap once a week.

The girls are starting to get some momentum now:

Oh, nice! They're just starting to hit that full on veg mode!
I love this stage, watching them put on inches every day!

How do those plastic (?) green tops fit on the big rock wool cubes?
What's their function? Are they just there to hold the drippers? Stabilize the plant?

They have small spikes on each corner that press into the block and hold them in place. They prevent algae and facilitate water distribution as well as hold the drippers. They will also allow me to add nutrients that I do not want to put in the reservoir. The H&G Algen Extract (cold extracted kelp) has a tendency to make the reservoir slimey; so I will just add that from the top one a week. One of the Zambeza Blue Brilliants is having a hard time and I may give her an additional dose of Cal-Mag is she does not snap out of it soon.

The white caps I had in the last grow work fine accept you cannot see if the drippers are working like you can with this setup. Since I am doing precision drip irrigation to waste it is important that each plant get it's full ration of fertigation.

They do not stabilize the plants and after I do the manifold training I will be adding a scrog screen to hold the plants up. These rockwool blocks get pretty light before watering starts each day when the plants get bigger.

Thanks for the details, appreciated!
I'm playing with a very, very simple DWC bubbler for some veges these days.

I was wondering about the stability thing, because those cubes aren't big.

Will you be letting the roots from the rock wool base just grow out into the tray?
Will you be covering them at all? Cover for whole tray? Or just ... clay hydro pellets...??

I like your attention to wet and dry cycles.

The roots just air-prune themselves; so it just all goes on in the cube! I thought i had a picture of one after harvest but cannot find it right now.

Day 19 and first pruning. I have used several manifold training styles and I think Nebula Haze's style is the fastest with good yields so that is the one I am using with these girls. Top at 3rd node and remove all growth below that in this pruning. It always seems so radical to me at first but the plants just love it. I do pruning like this at lights out so the plants have some nighttime to recover from the shock.

Awesome stuff.
Looking forward to seeing how this turns out.
