It seems that adding even a weak amt of veg nutes to the clone watering soln was in fact slowing them down. Now I'm just using pH 5.5-5.8 water on the clones until they have a good spray of roots, when they get chucked in the flowering area. Back to reliably seeing first roots out of the cubes in 7 days.

Yes, all of the information I have felt was reliable said they use weak flowering nutes because it lower in N. This is the reason the author I read said you get better result cloning if you flush the mothers for a few days before taking clones. It drops the N 'which inhibits early root development'. Works out for me not using the mothers , thats another story. Good to see ya. VV

The speed of first roots showing is about the same as before adding the thermostat, but the development of profuse roots has come around much more quickly.

I would normally be doing a new batch of cuttings on the day I plant out the preceding batch. However, in this case, because the flowering area is on a 2-week rotation, I'll have to delay doing another batch to avoid feeding clones into the flowering room too quickly and having to remove plants from the other end of the pipeline before they are fully mature.

Since the clonebox looks like it will have future batches ready for planting in 12 days instead of 15, I'll time my next batch of clones accordingly.
what kind of nutrients do you use? and what is the mix per gal? im having a hard time coming up with a good level mix

I've heard about cutting back on the nutes for the mothers before taking cuttings, and I've done that for the last couple of years. Really don't know if it helps or not. And I use a weak flowering nute for rooting cuttings because of the higher Phosphorus, I thought. I've read in some nutrient regimens to use their PK Booster product for a rooting nutrient.

I think both are correct. The higher phosphorus content helps. Actually I think it was you that suggested the flowering nutes originally and I followed that when I used the rockwool cubes. VV

The first harvest will be of those clones I took from the flowering plants, so they have multiple branches instead of the single cola so I will probably get a lower yield from them. We have had hot, humid weather for a few weeks now so everything has slowed down a little. I figure another three months I should have it all going smooth.
? did u switch to the t-5 because heat was a issue, and if so what type of heat did u have with the hps lights?

The pH adjuster sauce I use is simply phosphoric acid. No N at all compared even to weak flowering nutes.

I use Canna Vega and Flores. Mix rate is 400ml each A & B in a 125L tank of tap water. Yields 1400ppm @ pH 5.7 with pH 7.1 makeup water. Tanks are dumped every 2 weeks.

Tank 2, which of course feeds tray 2, for plants in wk2-4, gets 50ml of Canna PK-13-14 in week 3. Plants are only exposed to PK for 1 week before the tank is dumped and the process repeated for when the next batch advances from tray 1 (wk0-2).
