update
Alright,
Still a slow build. Got the cage on the ceiling for the lights, and been working on the veg room. I now have 9 tangerine dreams (a killer pheno I found that doesn't stretch and finishes in 9 weeks) in and growing strong (popped roots out the bottom of the rock wool in 2 days. They are in the system, so now I figure I have to be built out by the end of next week, or the girls will be f worded. Gotta love the pressure. :sweating
I was going to use the purple kush like DD, but I already hastily put these Tangy's in, so my idea is to move the tangy's out to the flower room when its done, and replace them with the pk's. Then I will veg and bud them in the prototype veg chamber. Since they finish at around 8weeks with flush, the timing should be just right and will make up for me lagging.
This weekend I am going big.
I have designed a 9 plant site MPB to see if I can cut a week off my veg time, and provide a smooth transition. They are under a 600 right now, which I will dial up to a 1000 this week. I am using the rockwool 6" cubes that are low profile. They are meant to drain better vertically. If you look at how they are woven, you can tell the difference. Figured it would be ideal for 24/7 drip.
Need to change the reservoir to a 110 gal instead of 85 for this to work, and lower the water level a little in the "mini res". Right now the main res is smaller than the "min res". This means that the lower res will run dry before the top one is draining back after initial fill, which makes mixing nutes and adjusting pH a bitch.
I am pretty sure this is why DD said when he added nutes, he would be reading 5.0, and the next day it would be higher around 5.8... There is residual water in each mini res, and the cubes/hydroton. It takes a while to mix through, so I think that is where the balance was happening.
Initial thought:
UC has the advantage over MPB as far as adjusting pH, if you aren't using a doser. Going from main res, in to mini res, and then back... it takes a while.
