Plans were to harvest Today but I want to flush them at least two times. Sooooo yeah, waiting for the soil to dry to flush one more time & chop em' down!!
might i make some suggestions to improve next harvests yield?
1.keep temps in the 70-80 range, and try to keep them from deviating more than 10 degrees in range. if you are enriching with co2 this range jumps 85-90 with co2 saturation being at 1100 ppm. most people dont know this but most c3 plants(cannabis) have a co2 saturation point of 1200. after that more ethylene is built up and you dont want that
2.keep humidity always above 50% and always below 70% for veg 55-65% is optimal for flower, 50-55% is optimal. for co2 enriching humidity stays at those values
3. improved ventilation will help increase co2 getting to the plants.get a fan with a fan speed controller and you can fine tune the temps as well. your current ventilation is adequate though but to improve it keep the exhaust fans mounted high as possible with the intake mounted low as possible and on the side opposite the exhaust. this way there is an updraft blowing co2 rich air through the leaves while making it harder for any pests to lay eggs on the undersides of the leaves
4. dont flush right before harvest. its best to flush 2 weeks before and at least 2 days before cutting so they dry out better. wont exactly help yield but will reduce the chances of mold which actually could help yield.
5. blue spectrum isnt beneficial to flowering. it wont hurt but youd do better to have all 2700k lights in there as red light increase bud production. also red light in veg is counter productive as it causes stretch. however red light improves root growth and a combination of red and blue is very beneficial in the seedling stage but start to switch out the red so that after 1-2 weeks of veg it is mostly if not all blue light.
6. it has been noted that talking to your plants is good, this is because of the co2 you breathe out not exactly the sound. although there have been studies of music in the grow room improving yield vs control group. breathing slash talking to your plants whenever you can will yield higher co2 for about a couple seconds. if i breathe on my co2 meter it goes up 600 ppm.
7. for the first 2-3 waterings use molasses to boost the microbe population. this will help break down nutrients for your plants to use. after the 3rd watering with molasses dont do it again, normally microbes feed on the sugar from the roots and when you introduce outside sugar they eat that instead. yure just trying to boost their population not help them graze lol. keeping microbe feeding on your roots will help the plant uptake nutes even faster.
8. before flowering give your 2 days of absolute darkness. this kicks the flowering hormones into overdrive. likewise before harvest give it 2 days of darkness as well to help leach nutrients out of your bud.
9.phing your water isnt necessary with organics put 1-2 tbsp of dolomite lime or similar buffer in your soil as a top dressing would greatly benefit your plants
10. aerate your water with an airpump before watering. this will keep it oxygenated and help the plants recover from the watering quicker. likwise adding one capful of hydrogen peroxide to 1 gallon of water will do the same. do both.
11. when watering water completely. you cannot over water at one time this is why flushing works. you want at leas 10% runoff in your trays after words but get rid of the run off , the tray should have little to no water in it to prevent root rot. also do not water until all the soil even the bottom is bone dry. you basically want to get it completely wet leaving no dry pockets(this removes stale air from the soil) and let it dry completely.
12. if you water with nutrients make sure you give it 2-3 waterings with nutes and 1 without and repeat. also balancing your nutrients is important. in organics this isnt much of a problem but if you have been using 7-1-1 or similar nute during veg you want to use a 0-6-7 or similar nute during flower. too much of one nute will lockout the uptake of another.
13. no nutes the last 2 weeks of flower. helps more with bud quality than anything
14. never interrupt the dark cycle with light of any kind except green.
15. cut a 2 liter in half invert the top into the bottom to make a funnel and fill with vinegar. this will be a trap for almost all pests and they will be more interested in the vinegar than your plants. keep it 10 ft from the grow box
16. use a negative ion generator. negative ions have been shown to improve plant growth and half another benefit of reducing odors.
17. go to radio shack and get the strongest magnifying glass. use this to look at your trichs before harvest. you want mostly cloudy trichs when there are over 10% amber trichs its harvest time
i hope this helps you, the plants look great btw youre on your way to becoming a great grower
