Greetings I'm back from a much needed break from constant growing and foruming. I'm glad to be back and ready for another indoor season. Man, time passes by fast. already on my 4th closet grow trial. Not to mention the multitude of side experiments i neglect to document. This time around i'll try to be more in-depth with my nutrient scheme. If you want to see my previous trials: 1st - http://forum.grasscity.com/hydroponic-grow-journals/719674-my-first-hydro-grow-dwc-3.html 2nd - http://forum.grasscity.com/hydropon...wc-tray-system-400w-mh-hps-3.html#post9587096 3rd - http://forum.grasscity.com/indoor-grow-journals/794323-240w-led-sour-grape-haze-summer-fun.html Room Project - http://forum.grasscity.com/do-yourself/871247-4x8-18-site-dwc-custom-system.html#post11542676 Some changes i would like to note: New Bulb - Good old HTG supply. Super 400W HPS! Enahnce Blue Spectrum! 55K lumens! blah, blah, blah. It's a new bulb and i'm hoping it'll deliver on all the hyped advertising. Full Spectrum of Nutrients - My first grow i only used the Pro Grow and Pro Bloom. The 2nd and 3rd time i used i used Pro Grow/Bloom/Sweet/Hydroplex. Now i'm adding to the mix Liquid Karma, Cal Mag, Silica Blast and Aqua Shield. Plus you can see the other things i have to keep the magic going (calibration fluids, PH balance, cloning gel, neem oil) First Pic - Day 1, Second Pic - About a week later New Strains - I've finally moved on from the Sour Grape Haze. I've been smoking that stuff for way too long and i need to broaden my growing experiences. I have Sweet Tooth and Mr. Nice Guy. ST is growing insanely fast. First time i can notice growth each time i check it. Mr.NG lagging a bit and not the most robust looking plant, just like the first time i grew it, but damn this plant is fucking tough! Scrog - That's right. I finally did it. Going to see if i can pull off a scrog. What's crazy is i built that out of junk basically. Extra piece of green garden fencing i cut up and then lined the outside with wire from hangers and then attached with duct tape. Screwed duct tape to each wall and using the retracting zip lines for some extra anchors. Better Ventilation - With summer temps into the 90's, i couldn't afford to keep venting that hot air back into my room. I finally got around to drilling a hole in the ceiling and venting the heat into the addict. Dropped my temp dramatically, both in the grow closet and the house. First two days before the change, the grow the closet was hitting 100 degrees, causing some heat damage to the ST, but the Mr. NG was undamaged. Plant Stats - I swear i'm not trying to do this, but it seem that my nutrient concentration has slowly been going up over the week as the water is being used/evaporated coupled with the addition of a few drops of PH down every day to maintain 5.5-6.0. This is day 8 of veg. I'm giving them 18 hours of dalight vs 24 like i have in the past. Daily high about 90F and then usually won't get anything lower than 70F. rH 25-40%. Day 1-4 PPM 680-720 Day 4-8 PPM 720-760 Basically i followed the low end of this guideline and then diluted the concentration to about 650 with PH'd water. Now, I'll let it slowly get more concentrated as the water is used up and then just add my flowering nutes when my res gets low (if timed correctly) One thing i do not use is the CLeareX and Pro Grow Soil. I just use Bloom all the way through.
