I'd advise you to go slowly. Check the soil a couple of inches down - if it is dry then it's time to water. Add water until some flows out of the bottom and don't water again until the top two inches of soil are dry again. Yes you can use your hydro nutes but start at no more than half...
The plants are not that bad, they need a little nitrogen but don't over do it. 500 ppm is a good hydro target but if you don't have a TDs meter then 1/2 strength of any high nitrogen nute will work. Watering depends on lots of things but in general plan on watering every three or four days.
You only have to water about once a week or less if you've got them set up correctly. Since you added a little vermiculate with the perlite, water will wick up to the little roots so no worries there. And yes, you can keep them in the pellets.

13. how to plan your ventilation system? Weed likes temperatures between 65 f and 75 f without CO2 and up to 85 f with CO2. The basic decisions on how you construct your ventilation system are determined by whether or not you need...
even your relationship is probably a victim to the times as you'd undoubtedly have found a way to live and work together if the economy presented better options. I don't really like the idea of selling but I can sure understand it.
