Question

What should the ppm be for  a Milwaukee T73 tds tester with atc range 0 to 1999? 

Answer

The factory settings should be at  1132ppm. I would turn it up only between 200-250 ppm from the factory settings and keep an eye on the ph levels of your water and replace it when necessary.

Question

Question about the fresh air intake I know you can't have to much fresh air. I have 2 intakes one is from the window AC unit and the other is the central AC that I have coming into the room from the ceiling will this be enough fresh air.

Answer

Even with lots of air intake and outflow you still need to circulate the air inside the room. It cuts down on the temperature and it helps with the humidity levels of the room to keep the air flowing around in the room.

Question

During the transition period from veg.  to flower could you tell me what I should do at this point. I've been reading about it but I don't understand when am I to start the transition and when to change the strength of the nutrients and how much strength and for how long am I to leave the nutrients at that strength.  

Answer

During the transition period (when you turn your lights from 18 hrs. to 12 hrs.) you should stop using the grow nutrients and flush the soil the plants are in by pouring lots of water through them. I would do this in a tub because it makes it easier to clean up. Then in about 4 or 5 days after the soil dries up a bit from the drenching You switch your nutrients to budding (flowering) nutrients. There are lots of different brands but I find that using miracle bloom works O.K. Then after 4-5 weeks you stop using the nutrients and just use water. One week before harvesting your plants you should flush them again in order to get the best flavour from  your buds.
