This time what I've decided to do is "play with" some of them like you suggested. I think my best bet right now will be trial and error.
I couldn't agree more. Try to enjoy yourself while you are at it.
I haven't read the whole thread.. but here is my advice if you want a direction to head...
Try coco coir. It is impossible to over water. Just water when the pot feels noticeably lighter.. Pickup a bag of Coco Coir (House and Garden, Canna, ReadyGro, whatever) and a bottle of Dyna Gro liquid fert, 9-3-6 foliage pro... some ph strips and some ph down. Get a bucket and a pump to mix your water... have a drainable space (like a sink) to water your plants over.
If you need to save cash you can ex the pump,,, just stir with a large spoon or your hand.
Read the passage on soilless mix from the grow bible (cervantes). No $ for the book? Chill at Barnes n Noble for an hour.. Coco coir is a soilless mix. No nutrients in this mix, so all food comes from your water source (using Dyna Gro 9-3-6, low cost high quality fert that can be used from seed to harvest).
Pop your seeds in a 1 qt pot. (.30 cents each)
You might get algae on the surface (green), not a big deal, just lightly scrape it off as it shows... after your coco gets some cover (plant leaves) it will stop growing.
PH to 6.
Start with 1/8 teaspoon per gallon.
Move to 1/4 teaspoon per gallon after your first couple sets of leaves, maybe 5 inches growth
Move to 1/2 teaspoon per gallon when the plant is 8 inches tall.
Soiless is easy. You can't overwater, you can easily flush out a mistake, root systems do very well as long as you don't let the plant wilt.
Another piece of advice... rather than vegging under cfls... get yourself a T8 2 bulb 4 ft strip from Lowes... $20 for the fixture... 8 for the bulbs... Get a spectrum around 4100k. CFL are intense lighting from a single source... A T8 strip will be much easier to grow seedlings and veg under... to flower, you can always use the strip and then hang cfls off centered from the strip.
There is nothing wrong with MG soil. It is just easy to over water. If someone says MG will kill a plant it is because they either are not speaking from experience or they still have basic gardening skills to acquire. This is common in cannabis growing. Many (if not most) cannabis growers have no other gardening experience... lots and lots of hearsay.
If something in my post does not make sense or is something you already cleared up, i apologize, i did not read the whole thread.
