Hi all First time grower seeking some answers from any helpful growers out there. I am planning on growing a few plants from bag seeds I have accumulated over last few years. Not a large scale grow, just enough for me and some mates. I hope to veg under 2 T8 fluoros (18w each - circular LST) and flower with a 600w Lucagrow HPS I have. I threw 6 seeds into damp tissue covered with upturned saucer and placed on warm/hot (7 days ago) and 1 germed within 24 hours, threw him into some garden soil and put under said fluoros. 2 days later I still had no action from the others so I replaced the ungermed seeds along with another dozen or so in some new tissue. So far I have had no new action from seeds. Germinated seed has only today sprouted however shot to about 2" with 1 leaf set, has me quietly confident . Let me precede my qq by saying I have been scouring these and other forums over the last week gathering information and have just a few particulars I could not find. If they are obviously simple and available feel free to flame me. My qq: 1. I've read about testing seeds by flotation (good seeds will sink?). It would not be too late to do this would it? 2. Is there a minimum size growroom/box for my 600w light? I am currently designing a stealth like grow box and as I only want a few plants and want to use LST (for yield and space reasons). At the moment it looks like I will have about 10,000 lumens per sq ft or just over, I will make sure that the light/box is sufficiently cooled. 3. I haven't found a lot of information on humidity. It is coming out of winter here in southern hemisphere. Am I right in saying the seeds need more humidity to germinate than the planted seedling? 4. I know not to fertilize until flowering time. I have about 500mL ea of Dutchfest hydro part A and part B. Come flowering time would I be able to dilute this with water and feed the plant that way? Thanks in advance PS Thanks must go to all members of the forum who contribute constructively as they have helped create an incredible resource to us newbies out there. Keep it up, the world will always need another grower!
