Hows it going Retodd? I appreciate your subscription. Ok you asked about the solo cups, man really I got this from the site. Reading Nebulas tutorials and the others. Plus to me they are the best starting pots for seedlings. What I do is start the germination process in Jiffy Plugs, as the seedling sprouts I allow it to develop its first set of single serated leaves. When this has happened I wait about 2 or 3 days and plant the Jiffy Plug into the solo cup and just allow maybe a 1/4 inch of the plug to show above the potting soil (Fox Farm Happy Frog) which is a perfectly well balanced potting soil for seedling growth.
Now about the HID lights, the reason I started useing them is really reading the tutorials for all the growing lights and honestly I just wanted to give them a try first because of the benefits they can bring if used right and the truly only way in my own opinion to produce a good harvest with the HID'S is to use a Lux Meter to measure your light levels and lumens, without the lux you will either not give enough light or to much and give your plants light burn. All this is my own opinion of coarse but I stand by it 100%.
As I said thanks for your comments and your subscription and I'll be talking to you soon, have a good night and a great grow.
Thanks for the check in tho. Us Coreys are hard to kill
