Calculating nutrients feed.
First of all, your guess will be as good as mine, I have based my “plan or schedule” on 2 things:
So here is some info about my drum:
Please see Fig. 1 & Fig. 2
First of all, your guess will be as good as mine, I have based my “plan or schedule” on 2 things:
- Twice a day I dip the 1.5x1.5 RW cubes with the seedlings 6 mm deep in distilled water for 2-3 seconds and each time it amazes me how much water these RW cubes suck up in such a short time.
- In several old @420 posts, there was a member (maxximus) who grew cannabis in a rotating garden and when he was asked, he said that his RW 4x4 went only 6 mm deep in the nutrients. (he's not been here since 2009)
So here is some info about my drum:
- It takes my drum 39 minutes and 15 seconds for one rotation.
- That are 2355 seconds, divided by 360 (degrees) is 6.54 seconds per degree.
Please see Fig. 1 & Fig. 2
- Fig. 1 From the moment the RW hits the nutrients, until it leaves the nutrients are 36 degrees.
- 36 degrees are 36 x 6.54 = 235.5 seconds or almost 4 minutes, that is the amount of time the RW 4 x 4 will be in contact with the nutrients.
- Please note that I can "fine-tune" the height of the overflow (now 6 mm) with tenths of millimeters up or down.
