Here is 1 of the 2 sip designs I will be adding to this thread. Second sip similar to greens design but using 6" black corrugated drain pipe as the support system. The ones in these pics are a modified design from another grower,
@hyroot, he has already proven this system. His threads are on this forum.
Build plan and parts:
Mine is a 12 gallon tote.
View attachment 4299291 Top cut out for inner base. Overflow hole, water level site tube in base of tote. 6" corrugated drain sections as the support system for inner base. 6" net pot epoxied to inner base bottom, garden burlap 3 layers thick to keep soil out of res but allow roots through.
View attachment 4299292 1" pvc fill tube. 10 gal fabric pot with bottom cut out for 6" net pot.
View attachment 4299293 Net pot wick filled with 50/50 coco/aeration mix. Aeration is perlite and pumice mix. Fab pot filled to 2 inches off top with my soil. Last 2 inches covered with pumice mulch to hold moisture and keep fungus gnats away.
Soil mix:
ROLS soil custom mix fairly similar to greens listed on page 1. Some amendments substituted for similar items due to availability and or cost. Approximately 120 gallons total mix made. Roughly 1-1-1 ratio with base/compost/aeration. 55 or so gallons of old soil with root balls from last grow, counting part of this amount as compost and also aeration. 35 to 40 gallons of new peat based mix, and 20 gallons compost EWC mix. Amendments and soil base parts all mixed. 2.5 cubic ft bag perlite added, and 5 gal bucket of pumice for aeration addition. My recipe was adjusted up with more P and down for less K inputs because the recycled soil added in already having sufficient K levels but Low P amounts. Biochar aldo added.
Growing schedule:
Let soil sit in tubs for 2 months. Clones started in solo cups and peat puck. At time of clone cutting 10 gal gets filled with dampened soil and covered with plastic. 1.5 to 2 weeks cuttings in solo cup growing roots, 1.5 to 2 weeks in 1 gallon up potting.
View attachment 4299298 3 to 4 weeks after cutting it gets up potted into 10 gal fab pot sip for 2 to 3 more weeks of veg. Total veg time 5 to 7 weeks from clone cutting to flowering room for a perpetual grow. 8 to 12 weeks in flower room, strain dependant as well as personal preference based on trichomes.
Thesis:
The shorter veg time should allow me more med sized plants, I like a variety. Shorter veg won't need the added size of the 18 gal tote for food, smaller design, more room for more plants, again, I like a variety. Lol. Will update when ive got more.
