So this or Jacks would be used the last 5-6 weeks with a last week of just water, yes? Mine are 11-12 weeks to finish and need that nitrogen (blood meal) or they fade. I only give it once a month and only once after they begin flowering. I also give them a monthly Espoma bio-tome 3-4-4 that I continue until the last several weeks. Again, only monthly. My soil has become much healther these past several years and I don't need to add too much, just try and replenish what they use.
Of course that's in the dirt and coco is inert. Interesting. Thinking of running hydro in buckets come summer. Some donut shops sell used buckets, food grade for a buck or two each. I got a cute 8 gallon aquarium from a client a few days ago with a built in filter and water pump, ordered a little pump on Amazon for a toilet water fountain and a drip system from Lowe's months ago. Wal-Mart has 100 2" baskets for $12 (currently out of stock) but I have time and don't just jump into something, If you haven't noticed.
The 99 Cent store had more coir, 8qts $1.99 so I bought 20 bags. Should last me a few months
I've been kicking the idea around for a few months, planned out the grows after several discussions and my experience this year with bud in frickin July.
What I need to do is stop parking my butt in my chair and taking 3-4 bong tokes and instead finish that greenhouse. Getting old and many aches and pains makes me wanna numb it but then I don't get much done. 18 days to go, Aug 23 seeds need to be planted for a Sept 1st pop date. Hottest part of the year. Gotta get it done!
