Guerilla grow/Spring harvest 2015

These are my seedlings. I started a few a couple weeks back. They just got their first diluted feeding yesterday... Also out of the picture, I have another 25 that are germinating/sprouting. They are bagseed from some mids I had. 2 to 3 strains. Of course from the crappy harvesting techniques, It was hard for me to judge taste and smell, but the high was great. One of those soaring, no ceiling, sativa dominant hybrid highs. One strain was brownish with a lot of pistils, and VERY resinous for mids. It was more resinous than some of the sensimilla I get. The other was a light green, also resinous for a bag with seeds in it. I don't usually deal with schwag, but these bags were bought solely for the seeds... I've been waiting on a order from attitude for about a month and a half, so desperate times call for desperate measures. I may be getting some clones soon, but not a sure thing.
Anyways, I plan on placing these out in the next few weekends after they get some food and growth on them. I probably will "weather" them during the day on the porch, for a few days prior. I plan on moving them to a remote location where I plan on having a temp, guerilla greenhouse (thinking about digging a few feet down so there is no impression above the surface of the soil, so the plastic isn't near as noticeable unless you walk up on it) then transfer to gallon pots. I'll leave them there until the threat of imminent freeze is gone, while they start to flower, then plant them into the ground and let them finish for another month or so. The equinox is March 20th, but I think photoperiod runs 12/12 until the end of April or so. There is a little guesswork, being that I don't know my flowering times, but from what I've noticed almost all commercial strains are flowering around the same amount of time (8-11 weeks) So I should be able to get a full harvest. If not, I'll have a shit ton of edibles.
This is my first spring harvest attempt, and first grow in general, in a long time. I am in South Texas and heard a few guys down here talking about it, also seen strain hunters Jamaica, a guy was mentioning several harvest outdoor a year. It has had me curious, so I figured I'd give it a shot. I was originally planning to grow Guanabana (sour amnesia x white widow) a commercial producer from Spain. I thought it would do well in this environment...
If you see any holes in my plan, or have questions or want clarification, hit me up. Holla!

I put my plants out a little earlier than planned, since they became root bound and weren't growing regardless.... I probably walked 8-10 miles today. I brought two backpacks and switched off after first drop. I found a small ledge on slight incline to hide them. They only be there a week or two, then will go directly in the ground at a few different spots. There's is 7 there under the plastic. Ill bring the others out this weekend when its time to water those again. 5 Will stay inside for another few weeks in gallon pots to veg for a bit. The others will go into flowering. they are very small only 4-5 internodes, so I don't expect much. More of an experiment since I've gotten a late start. seed issues... The 5 should do well. I hope to not get any males and I should have a little something to hold me over a few months until fall harvest.
