Pictures were taken on day 21. Increased ppm to a more aggressive mix to assist with growth. Decreased humidity to below 60%. COB's are at 100% and bloom is at 70% on the lights. Plants are a lot taller than expected. They have grown 20+ inches in a little over 2 weeks.
FloraFlex sells several types of cap that spread the water and imitate a drip system. They also prevent light from hitting your medium (while still allowing air to flow) so no algae and other issues light can cause. You can use just the caps and hand water or setup an autofeeder. floraflex.com I am also using their nutrients which are the only nutes developed specifically for cannabis, I will start a new diary detailing the strains im growing with these nutrients.
@Mr_Positivo Honestly I love it and cannot go back to hand feeding daily. I have done almost every type of setup out there with the exception of ebb n flow and the Floraflex one is by far the most convenient and really cheap if you buy at bghydro.com. The one thing I don't like about FloraFlex is it is confusing when you are first trying to decide what to buy from them. They have so many options and you don't know what would best suit you or what each one even does. I guess you can call ans ask them but I never do that for some reason. If you have any questions about their products including their nutes let me know.
