I had bought a cheap ph meter from amazon that broke on day one of the grow, and I couldn't find my old tds meter so decided to invest in a decent meter that would do ph/ppm/temp and display a constant reading (since I was going to monitor it with a webcam). I got a good deal on a bluelabs guardian from amazon and it was well worth the investment for hydro setup.
It was really hot in my tent (attic in summer) and the solution in the tank was as high as 33 degrees Celsius so I needed a chiller and ordered the cheapest one I could find on ebay, 35L aquarium chiller 100watts. Didn't expect much when it arrived as it was a lot smaller than I expected but I was very pleasantly surprised at its performance, was easily dropping the solution to a constant between 19-21 degrees
Can anyone offer advice or experience on harvesting some of the bigger more mature buds early while leaving the rest of the plant in tact to mature? Checked the trichomes and the big top buds look ready, everything lower down is clear/milky
things are looking good for you, doing a partial harvest is great, this way you cut off the top buds that are done, and leave the lower parts to stay in the grow until you want to harvest them.
real easy just cut to the buds that are not ready, hang the ready buds, wait and repeat. happy soon to be harvest, you did a great job grow friend
Tell me more about the setup you've got going! That blue bag in photo 1 of week 9 -- assume you pre-mix your nutrient water every few days and let a water pump do the work? Would appreciate you sharing the hardware you're using. My ladies are starting to DRINK and I need a solution like yours.
@WeedDoctorSam, I've got a little chiller that has a pump circulating the nutrients through some clear pvc tubing. To drain my tank all im really doing is interrupting the flow from the chiller back into the tank by pulling the return line from the chiller out of the top of the tank and placing it in the blue bag to drain. I usually wait until my tank is less than half full when I drain it as it's less effort (less water to pump out, move and dispose of) and less wasteful also (there are still unused nutrients in there)
When I can see air bubbles running through the chiller lines and the flow has slowed down significantly, I take the chiller return line (clear pvc tubing) out of the blue bag and place it back into the top of my tank, then I pump in my fresh batch of nutrients and im good to go for a few days
@Flowers_By_Irene, this is super helpful, thanks!
"...then pump it in when the old nutes have drained and I've put my return line back"
Can you say more about this? When the old nutes have drained = your grow tank 1/2 full or below?
And what does "when I've put my return line back" mean? THANKS and happy growin to you too!
